WATERTOWN, Mass. —
"It was very scary," she said. "There are two bullet holes in the side of my house, and by the front door there is another."
Christine Yajko said she heard two loud explosions and gunfire. She said a police officer later knocked on her door and told her there was an undetonated improvised explosive device in the street and warned her to stay away from the windows.
"It was on the street, right near our kitchen window," she said.
Tsarni, the men's uncle, said the brothers traveled here together from Russia. He called his nephews "losers" and said they had struggled to settle in the U.S. and ended up "thereby just hating everyone."
U.S. government officials, speaking on condition of anonymity because they were not allowed to talk about an investigation in progress, said Tamerlan Tsarnaev traveled to Russia last year and returned to the U.S. six months later.
His last known address was in Cambridge, Mass. He had studied accounting as a part-time student at Bunker Hill Community College in Boston for three semesters from 2006 to 2008, the school said.
Dzhokhar Tsarnaev was registered as a student at the University of Massachusetts Dartmouth. Students said he lived in a dorm there and was on campus this week after the Boston Marathon bombing. The campus closed down Friday along with colleges around the Boston area.
The city of Cambridge announced two years ago that it had awarded a $2,500 scholarship to him. At the time, he was a senior at Cambridge Rindge & Latin School, a highly regarded public school whose alumni include Matt Damon, Ben Affleck and NBA Hall of Famer Patrick Ewing.
The men's father, Anzor Tsarnaev, said in a telephone interview with AP from the Russian city of Makhachkala that his younger son, Dzhokhar, is "a true angel." He said his son was studying medicine.
