Boxing Trainer Knew Bomb Suspect, Slain Officer

The dead Boston Marathon bombing suspect and the Massachusetts Institute of Technology officer allegedly killed by the suspect and his brother have links to the same boxing trainer.
    
Bob Covino co-founded the Somerville Boxing Club in the late 1970s. He says 26-year-old bombing suspect Tamerlan Tsarnaev trained at that gym several years ago. Covino says the MIT officer slain by the bombing suspects, Sean Collier, began volunteering with him at a gym in a different location in Somerville seven or eight months ago.
    
Covino says it's very unlikely that the two men crossed paths, because he hasn't seen Tsarnaev for several years and Collier only came over recently.
    
Covino says Collier had been helping teach younger boxers. The officer also set up a website for the gym.

Bombing Suspects Had Cache of Explosives

The senior Democrat on the House Intelligence Committee says the two Boston Marathon bombing suspects had collected pipe bombs, grenades and improvised explosive devices before they confronted police.

Congressman Dutch Ruppersberger said that the brother who fled after a furious gunfight hurled some of the devices at police as he drove away in a stolen car.
    
The Maryland Democrat said, "They clearly amassed a small arsenal of explosives."
    
Ruppersberger, who was briefed by authorities,said U.S. law enforcement and intelligence officials plan to quickly pivot from their search for the surviving suspect to learn whether the brothers had any help or contact from terrorist groups inside or outside the U.S. Ruppersberger said authorities likely will ask Russian officials for evidence in Chechnya and other nearby Russian regions.

MIT Cop Killed, Transit Officer Wounded

Authorities have identified the transit police officer severely wounded in a shootout with the Boston Marathon bombing suspects.

MBTA Police Chief Paul MacMillan says the wounded officer is 33-year-old Richard Donohue. He is a three-year veteran of the department.

Gov. Deval Patrick says Donohue is in surgery at Mount Auburn Hospital in Cambridge.

The officer was critically injured in an early morning shootout Friday with the two suspects in the marathon bombings. One of the suspects was killed.

Earlier in the night in Cambridge, a Massachusetts Institute of Technology police officer was killed while responding to a report of a disturbance involving the two suspects. The officer died of multiple gunshot wounds.

Sean Collier, 26, an officer on the MIT campus, reportedly confronted the marathon bombing suspects after shots were fired on campus. Collier worked at MIT for about a year.
