A law enforcement official has confirmed that the suspect found in a boat in the backyard of a home in Watertown is 19-year-old Dzhokhar Tsarnaev, one of the suspects in the Boston Marathon bombing. He is the man known as Suspect #2 in the white hat in pictures released Thursday.
His brother, Tamerlan Tsarnaev, 26, known as Suspect #1 in the black hat, was killed overnight in an exchange of gunfire with police in nearby Watertown.
An uncle, Ruslan Tsarni of Montgomery Village, Maryland, told The Associated Press that the men lived together near Boston and have been in the United States for about a decade. They traveled here together from the Russian region near Chechnya. His uncle spoke to the press and said he is "ashamed" of the suspects. He added that he has not had any contact with the suspects and that side of the family for years.
Anzor Tsarnaev spoke with The Associated Press by telephone from the Russian city of Makhachkala on Friday after police said one of his sons, 26-year-old Tamerlan, had been killed in a shootout and the other, Dzhokhar, was being intensely pursued.
"My son is a true angel," the elder Tsarnaev said. "Dzhokhar is a second-year medical student in the U.S. He is such an intelligent boy. We expected him to come on holidays here."
Thursday 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.
Authorities have also identified the transit police officer severely wounded in a shootout with the 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.
Boston's police commissioner says all residents of Boston must stay in their homes as the search for the surviving suspect continues. The public transit system is shut down.
The suspects' clashes with police began only a few hours after the FBI released photos and videos of the two young men, who were seen carrying backpacks as they mingled among revelers at Monday's Boston Marathon.
The bombings on Monday killed three people and wounded more than 180 others, and authorities revealed the images to enlist the public's help finding the suspects.
