Federal authorities want to question her in the hopes she can shed some light on the motive behind the bombings that killed three people and injured more than 180.

Her lawyer, Amato DeLuca, said she did not speak to federal officials who came to her parents’ home in North Kingstown, R.I., Sunday evening, where she had been staying since her husband was killed during a getaway attempt early Friday.

Mr. DeLuca said he was discussing with officials about how to proceed.

“I spoke to them, and that’s all I can say right now,” he said. “We’re deciding what we want to do and how we want to approach this.”

But he revealed that Ms. Tsarnaev, 24, only discovered her husband was “Suspect 1″ in the bombings when she saw pictures on TV.

Her family — her father, Warren, 55, is a casualty doctor and her mother, Judith, 56, is a nurse — were also shocked.

“In the aftermath of the Patriots’ Day horror, we know that we never really knew Tamerlan Tsarnaev,” Judith Russell said in a statement.

Mr. DeLuca also offered new details on Tamerlan Tsarnaev’s movements in the days after the bombings, saying the last day he was alive that “he was home” when his wife left for work. When asked whether anything seemed amiss to his wife following the bombings, Mr. DeLuca responded, “Not as far as I know.”

Mr. DeLuca said his client did not suspect her husband of anything, and that there was no reason for her to have suspected him. He said she had been working 70 to 80 hours, seven days a week as a home health care aide. While she was at work, her husband cared for their toddler daughter, he said.

“When this allegedly was going on, she was working, and had been working all week to support her family,” he said.

Ms. Tsarnaev was attending Suffolk University in Boston when friends introduced her to her future husband at a nightclub, Mr. DeLuca said. They dated on and off, then married in 2009 or 2010, he said. They have a three-year-old child.
