Tsarnaeva's lawyer said she had no reason to suspect her husband of anything and was focused on supporting her family, working 70 to 80 hours, seven days a week as a home health care aide. Her husband cared for their daughter when she was away, Deluca said.
But Anne Kilzer, a Belmont, Mass., resident who went with her daughters to the Tsarnaev home to get facials from Tamerlan Tsarnaev's mother, said when she visited the apartment Tsarnaeva was always there with the baby and her mother-in-law.
Kilzer, who had not been to the home since around Labor Day, when the mother told her she was leaving the country, described Tamerlan Tsarnaev as surly and intimidating and painted his wife as cowed and intimidated by him.
"She was a very sweet woman, but I think kind of brainwashed by him," she said.
She said Tsarnaeva seemed lonely and would bring out the baby for her to hold when she visited.
The apartment was so cramped and crowded, Kilzer said, that it would have been difficult for Tsarnaev to hide criminal activity from his wife.
"Maybe she'll provide answers for all of us," she said.
Federal authorities have asked to interview Tsarnaeva, and DeLuca on Sunday told The Associated Press he is discussing with them how to proceed. He said on Tuesday during a brief statement to reporters that his client "is doing everything she can to assist with the investigation," although he would not answer questions about whether she had spoken with federal authorities.
DeLuca would not give the AP details on what his client told him her husband was doing in the days before and after the April 15 bombing but said as far as he knew nothing seemed amiss to her in the days after.
