 The graphic image emerged a day after police say Ciancia, of Pennsville, N.J., walked into the airport, pulled a Smith & Wesson .223-caliber assault rifle out of a duffel bag and started hunting for Transportation Security Administration agents, officials said. 
 
 The 23-year-old Ciancia allegedly shot and killed TSA agent Gerardo Hernandez, a 39-year-old father of two, at point-blank range and wounded five people, including two other agents. Then airport police shot the gunman four times, critically wounding him.

 “He is receiving medical treatment,” David Bowdich, special agent in charge of the Los Angeles division of FBI, said of Ciancia. “At this point he is unresponsive, and we are unable to interview him as of today.” 
 
 Officials revealed Saturday that Ciancia, after shooting Hernandez and noticing he was still moving, returned to finish the job. Surveillance video showed the gunman walk up to his helpless victim and open fire, killing him. 
 
 Reed Saxon/AP Shots were fired Friday at Los Angeles International Airport, prompting authorities to evacuate a terminal and stop flights headed for the city from taking off from other airports. 
 
 Ciancia’s duffel bag contained a handwritten letter stating he’d “made the conscious decision to try to kill” multiple TSA employees and that he wanted to “instill fear into their traitorous minds,” said FBI Special Agent in Charge David Bowdich. 
 
 Investigators said they discovered five magazines of ammunition inside the bag. Ciancia was not a ticketed passenger, officials said. 
 
 AP This photo provided by the FBI shows Paul Ciancia, 23. Ciancia, carrying a note that said he wanted to "kill TSA," pulled a semi-automatic rifle from a bag and shot his way past a security checkpoint at LAX, killing one Transportation Security Administration officer and wounding two others, authorities said. 
 
 Federal prosecutors filed charges of first-degree murder and commission of violence at an international airport against Ciancia. The charges could qualify him for the death penalty. 
 
 Also on Saturday, a report revealed Ciancia was carrying a note branding himself a “p----d-off patriot” and calling former Homeland Security Secretary Janet Napolitano a “bull-d-ke.”

 The manifesto contained the phrase “FU Janet Napolitano” and references to the “New World Order,” according to the report released by the Southern Poverty Law Center. 
 
 The handwritten note also reportedly said TSA agents violated Ciancia’s rights with searches and that he’d be happy to kill just one.

 Meanwhile, the mother of Ciancia’s former roommate, James Mincey, told The News the suspect ordered ammo and had it delivered to her son’s house in Los Angeles.

 Debbie Conway, 60, of Ohio, said Ciancia lived with her son for a short time about a year ago but kept having his mail sent there after moving. 
 
 “Jimmy asked Paul, ‘What’s in the box?’ and he said, ‘ammo,’ ” Conway recalled. “Jimmy said, ‘Don’t you ever have that crap delivered here. I’m a good citizen.’”

 Conway couldn’t say when exactly the box was delivered or what became of it. Her son called her late Friday after the unemployed motorcycle mechanic went berserk in the airport. 
 
 “He said, ‘Oh my God, Mom, he was my friend and I had no idea he was sick,’” said Conway. “He just talked and talked.”

 The alleged shooter who went on a rampage Friday at Los Angeles International Airport approached a Transportation Security Administration checkpoint, pulled a .223-caliber M&P-15 assault rifle from his bag and shot multiple times "at point-blank range" at a uniformed TSA officer, according to a criminal complaint filed Saturday.

 The gunman, whom authorities identified as Paul Anthony Ciancia, 23, of Los Angeles, then "began to walk up an escalator, looked back at the wounded officer, who in video appeared to move, and returned to shoot the wounded officer again," the affidavit read. 
 
 That TSA agent, Gerardo I. Hernandez, 39, was fatally wounded. Hernandez is the first TSA agent to die in the line of duty in the agency's 12-year history. 
 
 According to the criminal complaint, the shooter then fired at at least two other uniformed TSA agents and one civilian, injuring all three. Ciancia was pursued by law enforcement and shot in the chest by a sergeant and an LAX police officer. Ciancia remains hospitalized in critical condition. 
 
 He was charged Saturday with two felony offenses -- murder of a federal officer and commission of violence in an international airport. These charges could qualify him for the death penalty or life in prison without parole, U.S. Attorney Andre Birotte Jr. said, adding that the U.S. attorney general would decide whether to seek the death sentence.

 Law enforcement officials said Ciancia had a handwritten letter on him that stated the 23-year-old had "made the conscious decision to try to kill" several TSA employees to "instill fear in your traitorous minds." Other reports indicated the suspect was also carrying a “manifesto” associated with the antigovernment “patriot” movement. 
 
 Given that loaded weapons are forbidden in airports -- with the exception of law enforcement agents with a special reason to be armed -- Ciancia was carrying the rifle illegally. And transporting or importing most semiautomatic rifles is against the law in California. 
 
 Ciancia also had five magazines of ammunition with him, the affidavit showed.

 Federal investigators probing what motivated a gunman to shoot security checkpoint workers at Los Angeles International Airport are looking for connections to a long-circulated conspiracy theory that the U.S. government is preparing to oppress citizens under a totalitarian state. 
 
 The FBI got a warrant Monday to search the cellphone of alleged gunman Paul Ciancia for materials reflecting his "views on the legitimacy or activities of the United States Government, including the existence of a plot to impose a New World Order," according to court documents. 
 
 Ciancia, a 23-year-old unemployed motorcycle mechanic, got a ride to LAX on Friday morning with a roommate, walked into the airport and began targeting Transportation Security Administration officers, according to authorities. By the time LAX police officers subdued him with several gunshots, one TSA officer had been killed and two others injured. 
 
 On Monday, Ciancia's family offered sympathy to the family of slain TSA screener Gerardo I. Hernandez, who came to the U.S. from El Salvador as a teenager. In a brief statement read by a family attorney in Ciancia's hometown of in Pennsville, New Jersey, family members also expressed shock at the rampage and hope for the recovery of the surviving victims. 
 
 One of those officers, Tony Grigsby, spoke for the first time publicly, saying he was trying to help an elderly man get to safety when the gunman shot him in the right foot. He hobbled with a cane outside his South Los Angeles home, where he fought back tears recalling Hernandez as a wonderful person who will be missed. 
 
 "Only now it has hit me that I will never see him again," Grigsby said. 
 
 The other wounded TSA officer has been released from the hospital, the agency said, and on Monday the condition of high school teacher Brian Ludmer, who was shot in the calf, was upgraded from fair to good. 
 
 Why airport security officers apparently came to personify oppression to Ciancia is still unclear. 
 
 Both the assault rifle that Ciancia allegedly used and a handwritten note found in a bag he brought had TSA inspection stickers on them, according to a law enforcement official briefed on the investigation who wasn't authorized to speak publicly and requested anonymity. 
 
 The rant spoke of how Ciancia believed TSA searches were a violation of constitutional rights and he used a vulgar term to refer to Janet Napolitano, the former secretary of the Department of Homeland Security, which oversees TSA. 
 
 The screed also mentioned the "NWO," an apparent reference to the new world order belief that holds that an international cabal of elites is planning to take away the guns and personal freedoms of Americans. Perceived masterminds behind the conspiracy have shifted over several generations, among them bankers, communists and the government itself. 
 
 The TSA does not regularly feature as a target of the theory's ire, according to Mark Potok, who has studied extremist groups for the Southern Poverty Law Center. More typically, believers focus on another homeland security agency, the Federal Emergency Management Agency, which according to the theory plans to build camps to detain resisters to the new order, Potok said. 
 
 Potok said he has seen no evidence that Ciancia was personally involved in hate groups. 
 
 The alleged gunman remained in critical condition Monday and any court appearance on charges of first-degree murder of a federal officer and committing violence at an international airport will depend on when his doctors say he's ready, FBI spokeswoman Laura Eimiller said.

NBC's Miguel Almaguer reports. 
 
 A man carrying anti-government material and an assault rifle shot his way through security at Los Angeles International Airport on Friday, killing a Transportation Security Administration worker and wounding two others — after sending a suicidal text message to his family, authorities said. 
 
 NBC News Paul Anthony Ciancia 
 
 The gunman who sent travelers diving for cover and fleeing onto the tarmac — identified by authorities as 23-year-old Los Angeles resident Paul Anthony Ciancia — was shot in the chest by law enforcement and taken into custody in critical condition. 
 
 The TSA confirmed the identity of the slain officer as 39-year-old Gerardo I. Hernandez, according to an agency official. Hernandez is the first officer to have been killed in the line of duty in the agency's 12-year history. 
 
 Law enforcement officials said at a news conference Friday afternoon that the crime scene is extensive and that authorities are still investigating the suspect's background. While airport terminals 1 and 2 are being reopened, Terminal 3 remains shut down, officials said. 
 
 The motive isn't clear, but it's believed the suspect had anti-government views based on written materials he was carrying, the officials said. He texted his brother in New Jersey before the shooting and said he was thinking about killing himself, police told NBC Philadelphia. 
 
 Federal officials told NBC News it was unclear whether the gunman was targeting the TSA or was trying to shoot his way farther into the airport. But a witness said the shooter, calmly walking through the terminal with his weapon, approached him with a one-word question. 
 
 "All he said was, 'TSA?' Just like that," Leon Saryan told MSNBC. 
 
 The shooting started about 9:20 a.m. (12:20 p.m. ET) at Terminal 3, which serves Virgin America and other airlines. 
 
 NBC News Authorities believe the gunman used a a .223-caliber semiautomatic assault-style rifle. 
 
 The gunman walked through an "exit" lane reserved for passengers leaving the secure area of the airport, pulled the .223-caliber semiautomatic assault-style rifle out of a bag and opened fire at the security checkpoint, officials said.

 As he walked through the terminal, still firing, airport police pursued him. At a cluster of restaurants in the rear of the terminals, near the waiting area for some of the gates, they shot him several times in the chest, law enforcement sources said. 
 
 "He's been shot and he's been treated. He survived," Los Angeles Mayor Eric Garcetti said at the news conference. 
 
 The mayor added that the suspect had "more than 100 more rounds that could've literally killed everybody in that terminal today." 
 
 When the gunfire erupted, travelers who were waiting to snake through the security line suddenly had to abandon their suitcases and hit the ground. 
 
 "We were just standing there in line, and somebody started shooting," said Nick Pugh, a witness, who told NBC Los Angeles that he heard eight to 10 shots. "Everyone dropped to the floor and started crawling along the ground." 
 
 The shooting brought one of the nation's busiest airports to a standstill. 
 
 Eyewitness Leon Saryan talks about his experience at the Los Angeles airport and his interaction with the gunman. 
 
 Officials said 746 flights were affected, 46 of which were diverted. The rest were held on the ground in Los Angeles or at their originating airports, said Gina Marie Lindsey, executive director of Los Angeles World Airports. The ground stop applied to airports roughly west of and including Denver, officials said. It was imposed shortly after the shooting began and was lifted at 3 p.m. (6 p.m. ET) 
 
 "This has been a trying day for everyone, I know," Lindsey added. 
 
 The Federal Aviation Administration grounded flights at LAX, where 1,500 flights take off and land every day. Passengers heading there for departing flights were stuck in colossal traffic jams. Some abandoned their rides and rolled their suitcases the last distance to the airport. 
 
 Saryan said he was "cowering in a corner" when the gunman came over and asked whether he was with the TSA, even though he was in street clothes. 
 
 "He was calm. He was walking slowly," Saryan said. "He must have felt that he was in control, because he had his weapon and nobody else did at that time. 
 
 "But for the grace of God, you know, I would have been one of the fatalities," he said. 
 
 The airport said that seven people were injured in all but that the nature of all injuries wasn't clear. 
 
 A doctor from Harbor-UCLA Medical Center said two victims were taken there, including Hernandez, who was killed by a round that broke into fragments inside his torso, causing massive bleeding and chest and abdominal injuries. 
 
 Shooting suspect Paul Anthony Ciancia carried anti-government written material that was critical of the federal government and the TSA, officials say. NBC's Pete Williams reports. 
 
 Dr. David Plurad said that the victim didn't have a pulse when he arrived and that surgeons worked for more than an hour to try to revive him. 
 
 "We made every effort to stop the bleeding and get the heart to beat on his own," Plurad said. 
 
 The union that represents TSA workers told NBC Los Angeles that Hernandez was a behavioral detention officer who scanned passengers for unusual behavior and had been transferred to Los Angeles from Montana recently. 
 
 Another TSA worker was shot in the leg, said Nico Melendez, a spokesman for the TSA. 
 
 Brian Adamick, an accountant who was waiting for a flight to Chicago, spoke with a TSA agent with a leg wound on one of the buses that sped to the tarmac to evacuate passengers taking cover there. 
 
 "His right ankle is injured and he gets on and sits in the seat next to me, and I said, 'Are you OK?' He said: 'I'm fine. I got shot. Don't worry, I've been shot before,'" Adamick told NBC News in a telephone interview. 
 
 "I said, let me take a look, and he pulls up the pant leg and there's a flesh wound — 3 to 4 inches — looks like it's straight out of Hollywood, maybe a drop of blood or two," he said. 
 
 Another witness told MSNBC that there was an initial round of shots, then a pause, then more shots. An airline worker told travelers, "Go out! Go out!" and people streamed down the stairs and onto the tarmac for safety, he said. 
 
 Former Los Angeles and New York Police Chief Bill Bratton discusses the shooting that killed a TSA worker and wounded others at the Los Angeles airport. 
 
 Authorities said the suspect was living in Los Angeles but is originally from Pennsville, N.J., where his parents and brother still reside. 
 
 Pennsville Police Chief Allen Cummings said Ciancia texted his brother in the morning and said he was thinking about taking his own life. The family called local police, who alerted Los Angeles police. Officers went to Ciancia's apartment; he wasn't there, but his roommates said everything was fine, Cummings said. 
 
 President Barack Obama was briefed on the shooting, the White House said in a statement. Obama called TSA Administrator John Pistole to express his condolences to the family and friends of those injured, including the TSA employee who was killed in the line of duty, a White House official said. 
 
 In 2002, an Egyptian national opened fire at the El Al ticket counter at LAX, killing two Israelis before he was shot dead. Authorities ruled it a terrorist incident, even though the shooter was not tied to a known group.

– Alleged LAX gunman Paul Ciancia told investigators he had acted alone after being dropped off by a friend in a black Hyundai, a police official tells the AP; that friend, officials believe, didn't know what Ciancia had planned. The accused shooter is currently under heavy sedation—and 24-hour armed guard—in the hospital, after being shot four times, the insider says. Ciancia was charged yesterday with murder of a federal officer and committing violence at an international airport, and he could face the death penalty, the AP notes. Meanwhile, more details of the attack and its aftermath are emerging. After the gunman shot Gerardo Hernandez several times at point-blank range with a .223-caliber M&P-15 assault rifle, he began to walk away—but then, video suggests, Hernandez moved. That's when Ciancia "returned to shoot the wounded officer again," says the criminal complaint filed yesterday, as noted at NBC News. The note he carried—which was similar to a suicide note—made his anti-TSA "intent ... very clear," says an FBI rep, per the Los Angeles Times. The note said he hoped to "instill fear into (TSA workers') traitorous minds," but didn't seek to hurt anyone "innocent." Contrary to prior reports, Ciancia, an out-of-work motorcycle mechanic, wasn't a ticketed passenger, the AP notes. Two other TSA officers injured in the shooting are now out of the hospital.
