"There was some discussion of who's coming in," Schoenfeld said of the patient. "Is it the suspect? Is this a victim? Is it a police officer?
"Ultimately that discussion died down quickly, because it doesn't matter who's coming in," he added. "We're going to treat them as best as we can, because you really don't know who it is until the dust settles."
When Tsarnaev arrived, he immediately went into cardiac arrest. CPR was performed until a team of doctors could attempt to resuscitate him, inserting chest tubes to treat potential injuries and gain vascular access to give the patient what Schoenfeld described as "massive blood transfusions."
Tsarnaev suffered from massive, penetrating injuries and was pronounced dead at 1:35 a.m. His body was turned over to law enforcement so that it can be examined by forensic experts, medical examiners and investigators to determine the source of his injuries.

Lesser added, "Driving into work I passed the gas station where the two suspects released the driver of the hijacked SUV last night...it struck me how coincidence plays such a large role in our lives." He said that the lockdown has given him "anxiety over how vulnerable we are."

"What century are we living in? she says. "We need evidence. Otherwise you can go shoot anyone like a chicken on the street. Not for me. We need evidence."
"All these pictures are on the computer. I have to see them. You have to have a motive first. Something that would drive you through some actions. They cannot go crazy or mad or sick just for one day. As far as I know them they are fine."
The aunt says bombings in Russia have been blamed on Chechens but were in fact part of a state conspiracy.
"What do you think, [that] I would believe something easily that your government, my government, their government would throw in my face? No. I want evidence."
She says Tamerlan Tsarnaev has a daughter.
"Tamerlan has his daughter, above the age of that little boy who died there. Why would he think that this daughter's life is worth more than that little boy's life that died there?
I don't trust the FBI. Show me evidence.

“Tragic events happened in Boston. As a result of a terrorist attack, people were killed. We already expressed our condolences to the residents of the city and to the people of America.
Today, as the media report, a certain Tsarnaev was killed during a detention attempt. It would be logical if he was detained and an investigation was conducted, all the circumstances and degree of his guilt explained. Apparently, the special forces needed a result at any price to calm society.
Any attempt to make a link between Chechnya and the Tsarnaevs, if they are guilty, is in vain. They grew up in the US, their views and beliefs were formed there. The roots of evil must be searched for in America. The whole world must battle with terrorism.
We know this better than anyone. We wish recover to all the victims and share Americans' feeling of sorrow.”

WHAT WE KNOW (9:10): For those just tuning in this morning, this is what we know. Just hours after photos were released of the two Boston Marathon bombing suspects, the suspects reportedly committed an armed robbery at a 7-11 convenience story near MIT.
According to NowThisNews, an MIT police officer was fatally shot multiple times by the two suspects. Just minutes later, the suspects commit an armed carjacking in Cambridge, keeping the driver hostage for 30 minutes before releasing him uninjured. Police then track the car down to Watertown, Mass., where a gunfight occurs and the suspects reportedly throw explosives into the street. Suspect #1, later identified as 26-year-old Tamerlan Tsarnaev, was killed in the gunfire exchange, and a police officer was injured.
The manhunt for the second suspect, identified as 19-year-old Dzhokhar Tsarnaev, has expanded from Watertown to the greater Boston area. The Associated Press reported that both brothers were from Russia near Chechnya had been living in the area for at least a year.
NBC News is reporting that two people are in custody at a house on Norfolk St, Cambridge and that the area is secured by dozens of FBI agents. Boston police are asking residents of Watertown, Waltham, Newton, Belmont, Cambridge and Allston-Brighton to stay in-doors. Massachusetts State Police is asking the media, "please do not broadcast video, locations of homes, cars being searched. It compromises officer safety.
