PROVIDENCE, R.I. — Federal authorities have asked to speak with the wife of suspected Boston Marathon bomber Tamerlan Tsarnaev, and her lawyer said he is discussing with them how to proceed.

Amato DeLuca told The Associated Press on Sunday that Katherine Russell Tsarnaev did not speak to federal officials who came to her parents’ home in North Kingstown, R.I., Sunday evening, where she has been staying since her husband was killed during a getaway attempt early Friday.

Tsarnaev, 26, and his brother, Dzhokhar, 19, two ethnic Chechen brothers from southern Russia, are accused of planting two explosives near the marathon finish line Monday, killing three people and injuring more than 180. A motive remains unclear.

DeLuca said he spoke with the officials instead, but would not offer further details.

“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.”

On Monday morning, Katherine Tsarnaev was seen leaving her house, in a car driven by her mother and escorted by two unmarked cars. Multiple news outlets reported she went to her lawyer’s office. She returned home shortly after 1 p.m., again escorted by unmarked cars.

Her lawyer did not immediately return messages left Monday.
