 Another morning stuck in a conference room, another requisite all-staff meeting, and Patrick Baccari arrived to find his co-worker Syed Farook sitting at a table by himself. He was wearing a button-down shirt and a long beard. Baccari walked over to join him. “Ready to be bored?” Baccari asked, because that was always their joke. San Bernardino County required its health inspectors to gather at least twice each year for a day of speeches and continuing education. “I’m ready,” he would remember Farook telling him and smiling back. 
 
 They sat together near the back of the room as it filled with 75 people, and soon their table was full, too. There was Chris Nwadike, a government worker for the past 25 years. There were Isaac Amanios, a 60-year-old father of three, and Denise Peraza, 27 and newly married. 
 
 A technician wheeled out a lectern. A supervisor stood up to welcome them. At some point after the first hour, Farook got up and left his papers on the table and his jacket on the back of his chair. 
 
 “Where’s Syed?” Baccari remembered someone at the table asking, and then a little while later Farook was back, this time with his wife, two assault rifles, two handguns and hundreds of rounds of ammunition. 
 
 What happened next took less than four minutes. Fourteen people were killed. Twenty-one people were injured. And so many in the San Bernardino County Department of Health were left doubting how much they knew about not only their co-worker but also about their government office and the country it represented. One health department supervisor sometimes referred to her team of inspectors as a “Little United Nations,” because they had come to San Bernardino from everywhere: Eritrea, Colombia, India, Mexico and Central America — the most diverse office in San Bernardino County. “No talking politics. No interoffice drama,” was how their supervisor, Amanda Adair, described the office rules. 
 
 After the mass shooting in San Bernardino, Calif., on Wednesday that left 14 people dead, details are starting to emerge about the two shooters. Here's what we know about Syed Farook and Tashfeen Malik. (The Washington Post) 
 
 Farook had always been one of the most agreeable, the quietest, and also among the best at his job, Adair said. He was a college graduate with five years of experience in environmental health. He had helped train his co-workers on a new computer program and won gift certificates to TGI Fridays as an interoffice reward for good performance. He had taken a long vacation from work once to travel to Saudi Arabia and see the woman who would become his wife. Early in the year, he had set up a baby registry at Target for his newborn daughter, and his office mates had thrown him a baby shower. They had asked to meet his new wife and teased him lightly when he demurred. 
 
 “We all thought he was doing great, having a family, but still the same guy — peaceful and quiet,” Baccari said. 
 
 “He got along with everybody,” Nwadike said. 
 
 So it was more than just the black mask and tactical gear that rendered Farook unrecognizable to so many of his co-workers when he returned to the meeting about 11 a.m. The division chief had just finished a talk about statistics. The county supervisor had announced more hiring for next year and then given everyone a five-minute bathroom break. 
 
 That’s when, investigators say, Farook and his wife drove up to the beige three-building complex of the Inland Regional Center on a quiet street in San Bernardino, driving a rental car with Utah plates. They approached the patio with unlocked doors that led directly into the conference room, investigators said, and that’s where Amanios happened to be sitting outside on his break. Amanios was shot and killed, and then the shooters entered the conference room, where bagels and pastries were still sitting on a buffet table and some employees had begun posing for staff pictures. 
 
 Baccari and Nwadike had just left for the bathroom on their break when they heard a blast followed by a series of gunshots. Baccari was reaching for a towel to dry his hands when a bullet ripped through the dispenser and sent shrapnel spraying across the room. “Get down, get down, get down!” Baccari yelled, even though he had no idea what was happening. They dove for cover on the floor. Nwadike hid in a stall. Parts of the ceiling fell down on them, and they pushed the bathroom door closed with their legs. Nwadike thought he could smell gunpowder. 
 
 Baccari thought he could hear muffled screaming coming in between the blasts in the conference room, about 20 feet down the hall. “It was like the world was ending in there,” he said. “We had no idea what it was.”

 It was 65 to 75 rounds fired over the course of about a minute, coming from a Smith & Wesson and two AR-15s, investigators would later determine. One bullet hit the sprinkler system. Water rained down from the ceiling. Gunfire pockmarked the walls, tipped over tables and ripped through the lectern. Dozens of people were shot, at least one as many as five times. The gunfire stopped, and then there were new sounds coming from the conference room. 
 
 “Oh my God. Oh my God. She’s bleeding,” said one woman, speaking into a cellphone as she sat next to Hanan Megalla and called Megalla’s husband to say that his wife had been injured. 
 
 “A lot of people are dead. Somehow I’m alive,” said Denise Peraza, 27, making a call to her sister from the conference room, where she had been shot in the back. 
 
 “Love you guys,” wrote Julie Paez, sending a text message to her family from the floor of the room at 11:20 a.m., according to a report in the Los Angeles Times. She took a picture of her face as she lay on the floor and sent it to them. She had been hit in the arm and in the stomach. Her pelvis was shattered. “Was shot,” she wrote. 
 
 Four minutes after the shooting had started, more people in tactical gear came rushing into the room with their guns drawn. “Police!” one said, and the officers moved through the conference room and then into the bathroom, where Baccari and Nwadike were still cowering. “Don’t take anything! Everyone get your hands up,” Nwadike remembered an officer saying, and they hurried the survivors through a hallway and out of the building, past the conference room where their morning had begun. 
 
 They gathered outside, waiting to be checked at a triage tent and then interviewed by investigators. By noon, at least one of those co-workers had told investigators that he believed one of the shooters could be Farook. 
 
 “That didn’t make sense to me,” Baccari said. 
 
 “He was doing fine. No problem at all,” Nwadike said. 
 
 “It’s all so confusing and disorienting,” Baccari said, because so much that was familiar had become unrecognizable, and behind him in the conference room the fire alarm was blaring, water was pouring down, and 35 of his colleagues were either wounded or dead.

Abby Phillip and William Wan in Washington contributed to this report. ||||| Syed Rizwan Farook, a 28-year-old suspect in a San Bernardino shooting attack that killed at least 14 people on Wednesday, enjoyed working on vintage cars, reading religious books and hanging out in the backyard practicing shooting targets, according to what appears to be his profile on a dating website. 
 
 In a profile page on imilap.com, a man who identifies himself as “farooksyed49” describes himself as a Chicago-born, Muslim male living in Riverside, California. He states his age as 22, indicating that the shooting suspect, Farook, created the profile six years ago. 
 
 
 
 
 
 
 
 
 
 
 
 The picture posted on Farook’s imilap.com profile page. The site describes itself as a “one stop source for Indian Matrimonial and Dating services.” 
 
 It appears that Farook, who is dead following a shootout on Wednesday with police, also created a dating profile on DubaiMatrimonial.com, where a “Syed Rizwan Farook” with the same username, “farooksyed49,” describes himself as a government employee born on November 6, 1987. 
 
 The Daily Caller first reported on the two profiles early Thursday morning. 
 
 In a press briefing overnight, police said Farook was a county employee who worked as an environmental specialist for five years. Co-workers have said he went to Saudi Arabia this year and returned to the U.S. with a wife. 
 
 Farook was at a holiday party on Wednesday and left angry “or something of that nature,” San Bernardino Police Chief Jarrod Burguan said. An attack at the venue took place shortly after that, killing at least 14 people in what was the deadliest mass shooting to the hit the U.S. since a massacre three years ago at Sandy Hook Elementary School in Newtown, Connecticut. 
 
 Police also identified a 27-year-old woman, Tashfeen Malik, as the second suspect in the shooting. Relatives said Malik and Farouk married two years ago and had a baby, who they left with a grandmother before the tragedy. ||||| San Bernardino, California (CNN) With the investigation still unfolding, much is unclear about Wednesday's deadly San Bernardino shooting at a center for people with developmental disabilities. 
 
 [Update 12:22 a.m ET Thursday] 
 
 The family has not been able to track down recently named suspect Syed Farook or his wife since Wednesday morning, said Hussam Ayloush, executive director of CAIR (the Council on American Islamic Relations). 
 
 Farhan Khan, the brother-in-law of the suspect Syed Farook, told reporters: "I have no idea why he would he do something like this. I have absolutely no idea. i am in shock myself." Khan said he last talked to Farook a week ago. 
 
 [Update midnight ET] 
 
 ATF tells CNN that one of the guns used in the shooting was legally purchased and traces back to someone believe to be connect with the shooting. The agency would not disclose the name of the purchaser. 
 
 [Update 11:56 p.m. ET Wednesday] 
 
 One of the suspects involved in the San Bernardino shootings has been identified as Syed Farook, an inspector with the county health department, who abruptly left the event at the Inland Regional Center before the shootings, multiple law enforcement sources tell CNN. 
 
 The sources said the residence in Redlands, California, surrounded by law enforcement is connected to Farook. It is that house where the chase began that led to the shootout with the occupants of the SUV. 
 
 The sources could not say for certain that he was in the SUV, if he was a shooter, or that he is one of the dead. The sources did say that Syed Farook is known to be a U.S. citizen. 
 
 [Previous story 11:56 ET] 
 
 Two suspects died in a gun battle with police Wednesday hours after authorities say they burst into a holiday party at a center for people with developmental disabilities and killed 14 people. 
 
 But it was unclear whether the furious shootout with the male and female suspects was the end of a daylong manhunt after the mass shooting at the Inland Regional Center in San Bernardino. 
 
 An FBI raid was unfolding late Wednesday at an apartment in Redlands, where authorities were serving a search warrant connected to the shooting. 
 
 Mass shooting 
 
 The violence began around 11 a.m. at the convention building at the Inland Regional Center where employees with the county health department were attending a holiday event. Witnesses said at least two shooters opened fire, killing 14 people. 
 
 Another 17 people were hurt -- many wounded by bullets from automatic-style rifles, some injured in the panic to escape. 
 
 The shooters fled in a black SUV, prompting a huge police response in the area. 
 
 As the hours passed, the hunt for the suspects continued with a tip taking officers to a home about 10 miles away in Redlands. 
 
 When detectives followed up on it, a black SUV with Utah plates passed by slowly then sped up and raced off, a law enforcement official close to the investigation told CNN. A police car spotted it and took up pursuit. 
 
 There was a shootout, the official said. The male suspect shot out of the vehicle while the woman drove. The SUV stopped a quarter a mile later, as an officer returned fire. 
 
 A device that looked like a bomb also flew out of the vehicle, Meredith Davis with the Bureau of Alcohol Tobacco and Firearms and Explosives told CNN affiliate KCAL/KCBS. The SUV was racing back toward San Bernardino, she said.

 Residents were stunned to hear the eruption of continuous gunfire. A barrage of bullets riddled the SUV's windshield. 
 
 A third person who was caught running near the scene was detained, but police aren't sure whether he was connected to either shooting. 
 
 The shooting occurred at the Inland Regional Center (1) in San Bernardino, California. Two suspects were shot and killed by police in a residential area (2) about two miles away hours after the initial incident. 
 
 Suspects dressed for assault 
 
 San Bernardino Police Chief Jarrod Burguan didn't say how old the suspects were or physically describe them in detail. He told reporters they were armed with assault-style rifles and handguns. 
 
 A law enforcement official told CNN the rifles were AR-15s or similar style weapons. 
 
 The man and the woman were dressed in what Burquan said was "assault-style clothing," describing it as "dark, kind of tactical gear." 
 
 He wouldn't say if he knew if they were related. 
 
 Witnessed text frightened messages 
 
 Hours after the shooting, the Inland Regional Center convention center was still an active scene. The bomb squad was working to determine whether they need to blow up two suspicious devices, one of which appeared to be a pipe bomb.

 Survivors of the mass shooting told of hiding in offices, bathrooms and closets, texting their loved ones that they feared they were next to be shot. 
 
 In the moments after the initial bloodbath, SWAT teams had scoured the facility, unsure whether the shooters were still there and looking for people hiding from the horror. 
 
 Marcos Aguilera received a text from his wife who works at the Inland Regional Center. 
 
 "She heard the shots and crying," he said. The situation became confusing when the fire alarm went off. 
 
 "Everyone was confused," he said, relating his wife's account. 
 
 A SWAT team eventually rescued his wife and two other co-workers. "When she exited the building, she said there were multiple bodies on the floor," Aguilera told CNN.

 WHAT PROMPTED THE GUNFIRE? 
 
 Police do not have a motive for the shootings, which ended with a gun battle on a San Bernardino street that left 28-year-old Syed Rizwan Farook and 27-year-old Tashfeen Malik dead. Authorities say they were the only two shooters, and relatives said the two were married. Investigators have not ruled out a link with terrorism and are also looking into the possibility that a workplace dispute triggered the massacre at a social services center for the disabled. 
 
 ___ 
 
 HOW DID THE SUSPECTS MEET? 
 
 Farook traveled to Saudi Arabia earlier this year and returned with a wife, said co-worker Patrick Baccari, who attended the holiday party Wednesday but was in the bathroom when the shooting started. Baccari says Farook was gone for about a month in the spring, and when he returned word got around Farook had been married. The woman he described as a pharmacist joined him in the U.S. shortly afterward, and they soon had a baby. Police described Malik as Farook's wife or fiancee. 
 
 ___ 
 
 HOW DID IT HAPPEN? 
 
 Baccari, who was sitting at the same table as Farook, said employees at the holiday party were taking a break before snapping group photos when Farook suddenly disappeared, leaving a jacket draped over his chair. Baccari stepped out to the bathroom when he heard explosions. 
 
 "I'm getting pelted by shrapnel coming through the walls," he said. "We hit the ground." 
 
 The shooting lasted about five minutes, he said, and when he looked in the mirror he realized he was bleeding. He was hit by fragments in the body, face and arms. 
 
 "If I hadn't been in the bathroom, I'd probably be laying dead on the floor," he said. 
 
 ___ 
 
 HOW DID THE FAMILY REACT? 
 
 The suspects Farook and Malik left their 6-month-old baby girl with Farook's mother early Wednesday morning, saying they had a doctor's appointment, said Hussam Ayloush, executive director of the Council on American-Islamic Relations. Ayloush based his comments on conversations he had with Syed Rizwan Farook's brother-in-law Farhan Khan, who appeared at a news conference late Wednesday as a family representative. 
 
 The young parents did not return to get their daughter for several hours, however, and their family became worried when they could not reach them after seeing reports on the news about the shooting. The family at first was concerned that Farook might be a victim of the shooting because they knew he worked as an environmental inspector at the county's health department and sometimes worked at the Inland Regional Center, Ayloush said. 
 
 The family only began to piece together the events around 2 p.m. — three hours after the shooting — when a reporter called with questions, Ayloush said. Family members were being questioned by police late Wednesday. 
 
 "We don't know the motives. Is it work, race-related, is it mental illness, is it extreme ideology? At this point, it's really unknown to us and at this point it's too soon to speculate," Ayloush said.

 WHAT DID FAROOK'S CO-WORKERS THINK OF HIM? 
 
 Baccari said his co-worker, who said he was raised on a farm with goats and chickens, was reserved. Several months ago Farook grew out his beard. He appeared committed to his family, and never displayed any unusual behavior or discussed any radical political views. ||||| Media playback is unsupported on your device Media caption BBC News filmed inside the house rented by Syed Rizwan Farook and Tashfeen Malik 
 
 President Barack Obama says the US "will not be terrorised" by Wednesday's mass shootings in San Bernardino, California. 
 
 "We are strong. And we are resilient," he said in his weekly radio address, adding that it was "entirely possible" the two attackers had been radicalised. 
 
 Syed Rizwan Farook, 28, and his wife Tashfeen Malik, 29, killed 14 people before being shot dead by police. 
 
 The FBI is investigating the shootings as an "act of terrorism". 
 
 The Islamic State militant group on Saturday hailed the attack, saying it had been carried out by "two supporters of the Islamic State". 
 
 The statement, carried by IS's al-Bayan radio, gave no indication that the group had any involvement in planning the shootings at the Inland Regional Center social services agency. 
 
 What we know about shooting 
 
 Who were the attackers? 
 
 "We know that Isil [IS] and other terrorist groups are actively encouraging people - around the world and in our country - to commit terrible acts of violence, oftentimes as lone wolf actors," Mr Obama said in his address. 
 
 "All of us - government, law enforcement, communities, faith leaders - need to work together to prevent people from falling victim to these hateful ideologies." 
 
 Later, the White House said Mr Obama had been updated on the investigation by senior officials, including FBI Director James Comey, who confirmed there was so far no indication that the killers were part of an "organised group or formed part of a broader terrorist cell". 
 
 The FBI is also investigating reports that Malik had posted a message on Facebook pledging allegiance to IS.

 Farook, who worked for the local health department, and Malik opened fire on an office Christmas party, killing 14 people and wounding 21. 
 
 FBI officers are trying to recover data from two mobile phones that were found crushed in a waste bin near the scene. 
 
 On Friday lawyers representing the attackers' family said the relatives were "in complete shock" and that they had no idea the two had been capable of such an attack. 
 
 Syed Rizwan Farook's sister, Saira Khan, told CBS News: "I can never imagine my brother or my sister-in-law doing something like this, especially because they were happily married, they had a beautiful six-month-old daughter."

 Tashfeen Malik was born in Pakistan and lived for 20 years in Saudi Arabia before moving back to her native country to go to university. 
 
 She and Farook, a US national, met on Muslim dating websites, the New York Times quotes officials as saying. The new couple spent about a week in Saudi Arabia last year, before returning to the US together. 
 
 She was granted a visa allowing people to enter the US to marry American citizens. Mr Chesley said Malik was very conservative. She did not interact with male family members and wore a burka, he said. 
 
 Front-page editorial 
 
 It is the deadliest mass shooting in the US since 26 people were killed at a school in Connecticut in 2012. 
 
 The couple used handguns and semi-automatic weapons that had been legally purchased in the US, police say. 
 
 Bomb equipment, weapons and thousands of rounds of ammunition were later found in their home. 
 
 In response to the shooting, the New York Times ran an editorial calling for stricter gun controls on the front page of Saturday's print paper. It is the first time since 1920 that the paper has run an editorial on page one. 
 
 "It is a moral outrage and national disgrace that civilians can legally purchase weapons designed to kill people with brutal speed and efficiency," the opinion piece said. 
 
 "America's elected leaders offer prayers for gun victims and then, callously and without fear of consequence, reject the most basic restrictions on weapons of mass killing," it added.

 The bomb-making equipment and the thousands of rounds of ammunition have all been removed, and the tan-coloured townhouse which Syed Farook and Tashfeen Malik called home has now returned to normal. 
 
 On Friday, the FBI completed their search of the property on this leafy suburban street, and after confiscating notebooks and computers - and even Christmas tree lights - handed the property back to its owner. 
 
 Waiting reporters were allowed a peek behind the venetian blinds, hoping to get some degree of insight into the life of the "clean-cut young man" and his young bride and baby, who never caused problems and always paid their rent on time. 
 
 And as we piled across the threshold, we encountered not the remnants of some medieval torture chamber - or even the evidence of a fanatical terrorist cell - but all the trappings of domestic mundanity: powdered baby food in the kitchen, a cot in the upstairs bedroom, nappies, books and tapestries and several copies of the Quran.

 Who were the victims? Diverse backgrounds of the 14 people killed ||||| WASHINGTON U.S. investigators are increasingly convinced the California shooters planned multiple attacks, given their stockpile of weapons, and are looking at whether the Pakistani woman involved radicalized her American husband, officials said on Sunday. 
 
 Investigators believe the weapons cache collected by Tashfeen Malik, 29, and her husband, Syed Rizwan Farook, 28, points to more attacks but they do not have evidence on other possible targets, a senior U.S. government source told Reuters. 
 
 The couple stormed a gathering of his work colleagues in San Bernardino, California, on Wednesday, opening fire with assault-style rifles and killing 14 people. The pair were killed a few hours later in a shootout with police. 
 
 U.S. authorities were trying to learn what contacts Malik might have had with Islamic militants in Pakistan and Saudi Arabia, where she grew up, the official said on condition of anonymity. 
 
 They lack clear evidence that the wife was radicalized overseas or that she in turn radicalized her husband, though they are actively investigating that, the official said. 
 
 Authorities are investigating the shootings as an act of terrorism. President Barack Obama scheduled an Oval Office address Sunday to outline how the country is responding to the broader threat of terrorism. 
 
 Malik's estranged relatives in Pakistan have said she appeared to have abandoned the family's moderate Islam and become more radicalized in Saudi Arabia, where she moved as a toddler. 
 
 She returned to Pakistan and studied pharmacy at Bahauddin Zakaria University in Multan from 2007 to 2012. 
 
 "There's a serious investigation ongoing into what she was doing in Pakistan and in Saudi," U.S. Representative Michael McCaul said on "Fox News Sunday." "We think that she had a lot to do with the radicalization process and perhaps with Mr. Farook's radicalization from within the United States." 
 
 "The wild card here is the wife Malik," said McCaul, the Republican chairman of the House Homeland Security Committee. He said investigators were also looking at where they got the money to acquire the guns. 
 
 U.S. Attorney General Loretta Lynch said U.S. authorities have no evidence that the shooters were part of a larger terrorism cell but were working with their counterparts overseas to gather information about their lives. 
 
 "We are trying to learn everything we can about both of these individuals," Lynch said on NBC's "Meet the Press." "It will be a long process, it will be an exhaustive process." 
 
 "And we are trying to learn as much as we can about her life before they met, after they met and frankly, after she came here as well. What we are trying to focus on again is what motivated these two individuals." 
 
 ISLAMIC STATE LINK UNCLEAR 
 
 McCaul said it was unclear what ties the couple had with the Islamic State, which has said the pair were "followers." At a minimum, he said, the militant group inspired the attack. Malik is believed to have pledged allegiance to the group in a Facebook posting shortly before the shooting. 
 
 "We have the computers. We have the devices. We are currently going through the forensics," he said. "The investigation is ongoing to find out what is precisely the connection between ISIS, say, in Raqqa and in the United States, and what was going on." 
 
 McCaul also noted that Farook had a large arsenal of semi-automatic guns, hundreds of rounds of ammunition and pipe bombs. 
 
 "We are looking at the terrorist financing aspect to this case. I believe on his salary, he was not able to buy this on his own," said McCaul. 
 
 U.S. officials have acknowledged they had no information about the couple before the killing other than routine matters related to Malik's immigration status in the United States. 
 
 Susan Rice, Obama's national security adviser, said the case illustrates the difficulties in detecting self-radicalized attackers. "That's a very real challenge and it's one that preceded ISIL and I presume one that will endure beyond ISIL and its defeat," she said on CNN's "Fareed Zakaria GPS."

– The colleagues Syed Rizwan Farook failed to massacre say he was a quiet, polite man who appeared to be happily building a life with his wife and their 6-month-old baby. Patrick Baccari, a fellow health inspector who shared a cubicle with the San Bernardino suspect, says the 28-year-old seemed to be "living the American dream" and had returned earlier this year from Saudi Arabia with a wife he met online, report the Los Angeles Times and the AP. That wife was Tashfeen Malik, who was shot dead with Farook after a police chase, hours after the couple allegedly opened fire on the San Bernardino County Public Health Department's holiday party, killing 14 people. (The details on their marriage and that trip to Saudi Arabia are still clarifying—the New York Times reports they were married two years, but other reports say it's been for a shorter time.) Colleagues tell the Times that Farook disappeared from the party just before a group photo was taken. In other developments: Police have not discussed a motive, though terrorism has not been ruled out. The AP notes that at a Wednesday night press conference, a Council on American-Islamic Relations spokesman said: "We don't know the motives. Is it work, race-related, is it mental illness, is it extreme ideology?" The CAIR rep says that according to family members, the couple left their baby girl with Farook's mother on Wednesday morning, saying they had a doctor's appointment, and relatives didn't realize what had really happened until a reporter called. Farook was born in Illinois to parents from Pakistan, reports the New York Times. Colleagues tell the LA Times that he was a devout Muslim, but that he didn't talk about his religion at work. "I haven’t heard anything," Farook's father told the New York Daily News, speaking before his son's name was made public. "He was very religious. He would go to work, come back, go to pray, come back. He’s Muslim." A brother-in-law conveyed the same sentiment: "I have no idea why he would do that, why would he do something like this," said Farhad Kahn at a CAIR news conference. "I have absolutely no idea. I am in shock myself." Early reports suggested three shooters, but Chief Jarrod Burguan of the San Bernardino Police Department says police are now "reasonably confident that we have two shooters and we have two dead suspects." In a CBS News interview, President Obama said the US now has a pattern "of mass shootings in the country that has no parallel anywhere else in the world." He noted that potential terrorists on the no-fly list can still buy guns. "Those same people who we don't allow to fly could go into a store right now in the United States and buy a firearm, and there's nothing that we can do to stop them," he said.
