I-Team: Still little known about bombing suspect's widow

Katherine Russell, widow of Boston Marathon bombing suspect Tamerlan Tsarnaev, stands during a hearing in district court Thursday, Jan. 9, 2014, in Wrentham, Mass., on charges of driving with a suspended license, speeding and driving an unregistered car.

Katherine Russell was the girl next door.

She was a good student, a talented artist and a dancer when she graduated from North Kingstown High School in 2007.

Russell and her two younger sisters grew up in an upscale neighborhood on Coriander Lane. Her father is an emergency room doctor. Her mother is a nurse.

The family's world was turned upside down one year ago when they learned Tamerlan Tsarnaev, Russell's then-husband and father of the couple's 3-year-old daughter, was killed as a suspect in the Boston Marathon bombings.

Federal agents descended on the Russell family's Rhode Island home.

"He had a thick vest on and turned around, it said FBI, which made me feel really weird. Something has got to be going on," neighbor Paula Gillette recalled.

Russell, through her Providence attorney, denied knowing about any preconceived terror plot.

Many thought the reaction was strange coming from an educated woman who lived with her husband and brother-in-law in the Tsarnaevs's cramped Cambridge, Mass., apartment. She had converted to Islam and always wore a traditional head scarf.

During the week of the bombings, neighbors told NBC 10 that the Russells often kept to themselves, and their privacy has only increased in the last year.

One neighbor told the I-Team that she rarely sees the family. It's unclear if Russell even lives in her parents' home.

Russell was never charged with any crimes and life, although different in the public eye, moved on as Russell continues to care for her young daughter, Zahara.

The 25-year-old answered to speeding and other driving charges in January in a Massachusetts court.

Investigators also continue to probe the bombings and called her parents, Warren and Judith Russell, before a federal grand jury in September. Her sisters, 20-year-old Anna and 22-year-old Rebecca, were also called to answer questions in December.

Will Russell herself face any charges?

An attorney who spoke to the I-Team and is very familiar with federal investigations said it appears to him that Russell is a target of the federal government.
