Authorities are asking to speak with Tamerlan's wife, who's been staying at her parent's house in North Kingstown. Investigators went to the home of Tsarnaev's in–laws Sunday evening, to question Katherine Russell Tsarnaev.
Her lawyer says, she did not speak with them, and that she didn't suspect her husband of anything. The lawyer says, Katherine was working 70 to 80 hours a week as a home health care aide, while her husband cared for their daughter.
Tamerlan was reportedly home when his wife left for work on the day he died.
