(Daily Mail)  Dzhokhar A Tsarnaev is believed to be a legal immigrant to the U.S., who arrived in the country one year ago from Chechnya.

He may have had military training, according to NBC. The 19-year-old, who attended Cambridge Rindge and Latin School, is an amateur wrestling champion.

‘Suspect 1’ who died in hospital is believed to be 20 years old and the brother of ‘Suspect 2’ Dzhokhar.

The older brother attended Bunkerhill Community College and was studying to become an engineer but took a year off to pursue boxing.

The drama unfolded hours after the FBI released images of two men named as suspects in the Boston blast which killed three and injured 176 on Monday.

The Middlesex district attorney said the two men are suspected of killing a Massachusetts Institute of Technology police officer on campus in Cambridge late last night, then stealing a car at gunpoint.

Dozens of police officers, FBI agents, national guard, K-9 units and SWAT teams rushed to Watertown after midnight after a reported car chase involving the two suspects in a black 2013 Mercedes.

A short time later, police received reports of a carjacking by two men who kept their victim inside the car for about half an hour, the statement said.

Police pursued that car to Watertown, where explosives were thrown from the car at police and gunfire was exchanged, the statement said.

‘During the exchange of the gunfire, we believe that one of the suspects was struck and ultimately taken into custody.’

A doctor from Beth Israel Deaconess Medical Center said the suspect died after suffering multiple wounds from gunshots and possibly the blast of an explosive.

Massachusetts Institute of Technology (MIT) in Boston issued an emergency alert at 10.48 p.m. on Thursday night reporting that shots had been fired putting an officer was down and that a shooter was on the run.

It has been reported that a ‘Hispanic looking man’ took the officer’s weapon from him before firing on him.

MIT posted this alert to their website

‘At 10:48 PM today gunshots were reported near Building 32 (Stata) which is currently surrounded by responding agencies.

‘The area is cordoned off. Please stay clear of area until further notice. Unknown if injuries have occurred.. Although the situation is considered active and extremely dangerous, an investigation is underway.

‘Updates will be provided at this site when more information becomes available.’

The injured officer was from MIT Police and was being taken to Mass. General Hospital where he is currently in a critical condition.

The campus newspaper ‘The Tech’ posted to Twitter, ‘Shots fired near 32 Vassar St (Stata Center), police officer down. Please stay inside.’

Massachusetts State Police initially said the officer has suffered ‘life-threatening injuries.’ He was transported to Massachusetts General Hospital.

Earlier on Thursday, FBI Special Agent Richard DesLauriers spoke at a press conference to release photos of two men identified as ‘suspect one’ and ‘suspect two’ from surveillance footage near the blast site.

Suspect one is dressed in dark clothes, a baseball cap and wearing sunglasses, while suspect two is clearly wearing a white baseball cap on backwards – both are seen in the images with back packs on.

Originally, Mr Green thought that his photograph also included the man referred to as Suspect Number One, who was wearing a black baseball hat, a dark hooded jacket and khaki pants.

Though there is a man wearing khaki pants in Mr Green’s picture, who is seen next to a woman in a pink jacket, the man in his picture is wearing a red jacket and is not believed to be the suspect being hunted down by the FBI.

Wanted: Suspect One (pictured back in khakis and a black hat) and Suspect Two (pictured front in a white hat and backpack) are the main suspects in the Monday bombings
