Updates in the Aftermath of the Boston Marathon Bombing Auto-Refresh: ONTurn ONRefresh NowFeedTwitter4:04 P.M. Canadian Arrests Not Tied to Boston Case, Officials Say Royal Canadian Mounted Police officials have announced the arrests of two men who they say had the capacity and the intent to carry out a terrorist attack against a passenger train. The police identified the men as Chiheb Esseghaier of Montreal and Raed Jaser of Toronto. The authorities said plans for the attack were linked to Al Qaeda. "While the R.C.M.P. believed that these individuals had the capacity and intent to carry out these criminal acts, there was no imminent threat to the general public, rail employees, train passengers or infrastructure," the police said in a statement. Police officials do not believe there is a link between the Canadian case and the bombings at the Boston Marathon, the Canadian Broadcasting Corporation reports. 3:36 P.M. Victims Are Expected to Survive Devastating Injuries All of the people injured in the Boston Marathon bombings last week are likely to survive, according to doctors interviewed by The Associated Press for a report released on Monday afternoon. The only person connected to the bombings who died after arriving at a hospital was one of the two suspects, Tamerlan Tsarnaev. He died after a gunfight with the police on the streets of Watertown, Mass., in the early hours of Friday. The survivors of the attack at the marathon suffered a range of devastating injuries, according to the A.P. report. That includes several people who arrived with legs attached by just a little skin, a 3-year-old boy with a head wound and bleeding on the brain, and a little girl riddled with nails. Even a transit system police officer whose heart had stopped and was close to bleeding to death after a shootout with the suspects now appears headed for recovery. ""All I feel is joy,"" said Dr. George Velmahos, chief of trauma surgery at Massachusetts General Hospital, referring to his hospital's 31 blast patients. ""Whoever came in alive, stayed alive." A majority of the people injured had been released by Monday afternoon, but 51 of them remained in the hospital, according to the report, including three in critical condition and five in serious condition. At least 14 people lost all or part of a limb, The A.P. said, and three people lost more than one arm or leg. While doctors said that the prognosis for most patients was generally positive, some still face potential dangers. Although doctors are optimistic, some patients still have life-threatening wounds. Complications can range from blood clots to infections. A few still have injuries that could require amputation, said Dr. Michael Yaffe, a trauma surgeon at Beth Israel. ""We have to see how these are going to heal"" over the next few weeks, he said. ""Blood supply is key ... The two biggest enemies we will face in the next two weeks are maintaining a good blood supply and preventing infection."" So far, the progress has been in the right direction. ""Every day they're a little better,"" Yaffe said. ""A lot of them have a long road of recovery ahead."" 3:00 P.M. Scenes on Twitter During a Moment of Silence A moment of silence was observed across the Boston area at 2:50 p.m., a week to the minute after the two bombs exploded at the Boston Marathon's finish line. People shared photos on Twitter, including several that we have included here from Copley Square, the State House, M.I.T., Boston University and the backyard of a writer working from home in Bedford, Mass. In honor of the victims, Boston.com went dark. Even the newsroom at The Boston Globe was quiet, a reporter observed. 2:40 P.M. Recovery Will Take Months, Boston Doctors Say A majority of the patients admitted to Boston Medical Center after the bombings have been released, according to three doctors who spoke to reporters on Monday. But for many of the injured, like those who had arms or legs amputated, it will be a long recovery, the doctors said. Their comments were recorded at a news conference by The Associated Press, which published a video to YouTube. Dr. Peter A. Burke, chief of trauma services at Boston Medical Center, said the hospital treated 23 patients after the bombing and admitted 19 of them. Doctors operated on 16 of the patients within the first eight hours after the bombing and have performed 23 operations in the week since the attack. Dr. Burke said 11 patients remained in the hospital, one of whom was listed in critical condition. Three are in serious condition and seven are in fair condition, he said. "We are happy to report that all of our amputation patients are nearly completed, and these patients are starting the process of both physical and mental rehabilitation, which is really going to be the next step in their care," said Dr. Jeffrey Kalish, the hospital's director of endovascular surgery. Speaking to The Boston Globe, Dr. Kalish elaborated on what life is like in the hospital for the patients, especially amputees. Dr. Jeffrey Kalish told reporters today that patients who underwent life-saving amputations are steadily returning to a changed life, but some patients have grown weary of hospital food and are bringing their own in. Most amputees are walking the hospital hallways using walkers or crutches, he said. "It takes a lot of work, and they have to learn new routines, but we are gearing up for a mass exodus to rehab,"" Kalish said today. "Everything is starting to return to a normal state."" Kalish also said that during the past seven days, military veterans who also underwent amputations for war-related wounds have come to the hospital and walked the halls with the patients, showing them "their life is not over."" But recovery can be a long and draining process, said Dr. Terence Keane, a psychiatrist at the Boston University School of Medicine. "Recovery from this, psychologically, is a marathon," he said. And as you heard from my rehabilitation physician colleague here, it will take months for people to recover. The Boston Globe has prepared a list of confirmed victims, which it has said it will update. 2:36 P.M. Video: Moment of Silence in Boston A one-minute silent tribute to the victims of last week's attacks at the Boston Marathon took place at 2:50 p.m. 2:06 P.M. Document: Criminal Complaint Against Suspect An 11-page criminal complaint spells out the federal charges against the surviving suspect, Dzhokhar Tsarnaev, 19, who has been in a Boston hospital since he was captured Friday night. The charges authorize the death penalty, according to a Justice Department statement. 1:57 P.M. Injured Police Officer's Condition Is Improving Richard Donohue Jr., the transit police officer wounded during a gunfight with the suspects on Friday, has begun breathing on his own, The Boston Globe reported in an update posted to Twitter on Monday afternoon. Officer Donohue was seriously wounded on Friday night as he helped police officers from Cambridge and the Massachusetts Institute of Technology pursue the suspects into Watertown, The Globe reported on Monday morning. A shootout ensued, during which a bullet ripped through Donohue's right thigh, hitting both branches of the femoral artery and the femoral vein. The wound drained him of life. "The officer's blood volume was almost entirely lost, to the point of the heart stopping," said Russell Nauta, chairman of surgery at Mount Auburn, said at a news conference Sunday. It took 45 minutes or so of "very aggressive effort," he added, to get Donohue's heart beating again. The Globe also said that doctors were "cautiously optimistic" that Officer Donohue would recover, but that it would take a long time for him to recuperate. Though he remains in critical but stable condition, doctors and family said that on Sunday that Donohue was well enough to open his eyes, wiggle his toes, and - more importantly - squeeze his wife's fingers. Once Donohue is no longer sedated - probably in the next few days, if all goes well - Nauta said doctors will assess the effects of the officer's wounds on the rest of his body. Donohue will then spend at least a week in acute care, followed by several weeks of rehab. 1:38 P.M. Charges Filed Against Boston Bombing Suspect The surviving suspect in the Boston marathon bombing was charged Monday with "using a weapon of mass destruction" against people and property in the United States resulting in death, law enforcement officials said. The suspect, Dzhokhar Tsarnaev, was charged before a magistrate judge as he lay in a bed at Beth Israel Deaconess Medical Center, officials said. In a criminal complaint unsealed in Federal District Court for Massachusetts, Mr. Tsarnaev was charged with one count of "using and conspiring to use a weapon of mass destruction" resulting in death and one count of "malicious destruction of property by means of an explosive device resulting in death," according to a Justice Department statement. If he is convicted, he could be sentenced to death. The charges were announced one week after the 117th Boston Marathon ended in two deadly bombings. A statewide moment of silence was planned for 2:50 p.m. on Monday to mark the moment that the pair of bombs, which were packed in pressure cookers, exploded. Michael Cooper and Peter Baker 1:22 P.M. Bombing Suspect Will Not Be Declared an Enemy Combatant As our colleague Charlie Savage reports, several lawmakers called over the weekend for the surviving bombing suspect, Dzhokhar Tsarnaev, to be declared an enemy combatant. But Jay Carney, the White House press secretary, said at a briefing on Monday that Mr. Tsarnaev, 19, who is in serious but stable condition at a Boston hospital, would be tried in the federal court system, as Peter Baker of The New York Times reports. 12:10 P.M. Suspect Returned to Campus After Marathon Bombing Dzhokhar Tsarnaev, the surviving suspect in the Boston Marathon bombing, returned to his dorm room at the University of Massachusetts Dartmouth just 48 hours after the attack that killed three people and injured more than 170 last Monday, according to reports by The Boston Globe and ABC News. Andrew Glasby, who lived one floor beneath Mr. Tsarnaev in the university's Pine Dale dormitory, told ABC News that he and Mr. Tsarnaev spoke on campus in the days after the bombing. Glasby said Tsarnaev, who was often referred to as Jahar, blended right back into normal college life and was "convincing" that nothing was amiss. I thought as it was just regular old Jahar. We had a typical conversation, he was not startled, he was not scared, he was not anything. He was just the same old Jahar," Glasby said. Glasby said that Tsarnaev offered to give him a lift home to Waltham, Mass., on Friday. Tsarnaev described his car as a green Honda Civic, which was the same car police initially said Tsarnaev may have been driving while at-large. Zach Bettencourt, another college friend, told CNN that he talked with Mr. Tsarnaev about the bombings when the two ran into each other at the gym. "I talked to him in the gym about the bombing, and he was like, "Yeah, man, tragedies happen all the time," " Mr. Bettencourt said. Quoting unnamed students, WBZ, the CBS affiliate in Boston, reported that students at the Dartmouth campus described the suspect as a "pothead" and a hard-core soccer fan who "never talked politics." In an article on its Web site, the station reported that "two of his classmates told WBZ-TV that he was on the soccer team, but missed practice on Monday and they hadn't heard from him since." Monday was the day of the marathon bombing. The Boston Globe reported that university officials confirmed that Mr. Tsarnaev returned to campus on Wednesday, worked out at the gym and spent the night in his dorm room. The Globe also reported on Sunday that law enforcement officials had been "combing the campus" since the citywide lockdown began on Friday. During the lockdown Friday afternoon, three black helicopters landed at the main entrance early in the afternoon, carrying about a dozen armed police officers who ran onto campus. Two U-Haul trucks arrived a short time later and drove onto campus; three U-Hauls had arrived earlier. Around 3:30 p.m., 11 State Police cruisers with lights flashing raced through the main campus entrance, followed by SUVs carrying personnel wearing military fatigues. 11:29 A.M. Scenes From the Funeral for Krystle Campbell in Medford As our colleagues report, wakes and services began over the weekend for the victims killed in the marathon bombing. On Sunday, hundreds of people attended a Mass at St. Ann's Church in Dorchester for Martin Richard, the 8-year-old boy who was killed in the attack. On Monday night, Boston University students and faculty members will gather at a service for Lu Lingzi, 23, the Chinese graduate student who died in the bombing. And later this week, the Massachusetts Institute of Technology will remember the campus police officer, Sean A. Collier, 26, who was shot and killed by the suspects three days after the bombing. On Monday morning, Jess Bidgood reports, hundreds of people gathered at St. Joseph's Roman Catholic Church in Medford for a funeral Mass for Krystle Campbell, 29, a restaurant manager who was killed as she waited at the race's finish line with a friend. Gov. Deval Patrick and Representative Edward J. Markey were among those in attendance. Not everyone could get inside the church. Julie Dziamba, 21, lingered outside during the service. Ms. Dziamba had worked under Ms. Campbell at the Summer Shack restaurant. "She always had a smile on her face, even if she was mad at us for not cleaning up or getting things done on time," Ms. Dziamba said. The day after Ms. Campbell was killed, her mother, Patricia, described her as "the best daughter," who was loved by "everyone who knew her." 10:22 A.M. Suspect Was Possibly in New York City Last Thanksgiving As our colleagues Eric Schmitt and Michael S. Schmidt report, law enforcement authorities believe that the suspects in the Boston Marathon bombing were most likely planning more attacks. Federal officials said they were increasingly certain that the suspects had acted alone, but that they might have been inspired or trained by someone. An investigation is under way into a trip to Russia last summer by one of the suspects, Tamerlan Tsarnaev, 26, who maintained a YouTube channel that included links to videos of extremists. The other suspect, Dzhokhar Tsarnaev, 19, who remains in serious but stable condition at a Boston hospital, posted messages on his Twitter account last year that mentioned trips to Washington last summer and to New York City around Thanksgiving. Last July, the younger Tsarnaev brother posted several messages about being on a train to Washington, including this one: 9:19 A.M. Moment of Silence at 2:50 P.M. Monday in Boston The post at 1:38 p.m. misspelled the first name of one of the Tsarnaev brothers. It is Dzhokhar, not Dzohkhar.
