Federal authorities have asked to question the wife of suspected Boston bomber Tamerlan Tsarnaev, according to her lawyer.

Katherine Russell Tsarnaev found out that her husband was a suspect in the Boston Marathon bombing - that took place on April 15 - by seeing it on TV, Amato DeLuca told The Associated Press. He added details about days after the bombing, saying Tamerlan "was home" when he wife left for work on the last day she said she saw him alive.

'We're deciding what we want to do and how we want to approach this,' DeLuca said.

When asked if anything seemed amiss to Katherine after the bombings, he replied, "Not as far as I know," adding that she did not suspect Tamerlan of anything.

"When this allegedly was going on, she was working, and had been working all week to support her family," he told the AP. According to her lawyer, Katherine has been working 70 to 80 hours, seven days a week, as a home health care aide. While was worked, Tamerlan cared for their 3-year-old daughter Zahara.

Katherine, 24, did not speak to officials outside her parents' home in Rhode Island on Sunday night. She has been staying with her family since her husband was killed on April 18 following a shootout with police, according to Daily Mail.

She was photographed outside her home in Cambridge, Mass., over the weekend. She wore a leopard-print hijab and was spotted quickly collecting her belongings - her cat, a shopping bag and duffel bag - before driving away in a white Volvo with her daughter, according to New York Post.

Tsarnaev and his brother, Dzhokhar Tsarnaev, are suspected of planting two bombs at the Boston Marathon on April 15, which killed three people and injured over 140 others. Tamerlan was killed April 18 while partaking with his brother in a shootout with police. Dzhokhar fled the scene but was captured by authorities on April 19 with serious injuries. A motive for the bombings have not been revealed yet.
