Katherine Russell, who was married to Tamerlan Tsarnaev when he allegedly planted two pressure cooker bombs with his brother Dzhokhar Tsarnaev at the finish line of the Boston Marathon, is still largely a mystery as her brother-in-law’s trial looms.

Will Katherine Russell Appear At Bombing Trial?

Russell has managed to remain more or less under the radar since the bombing at the Boston Marathon in 2013 took the lives of three bystanders and seriously injured dozens of others. Immediately following the attacks, she moved in with her parents in Rhode Island with her and Tsarnaev’s daughter and lived a quiet existence.

“As a mother, a sister, a daughter, a wife, Katie deeply mourns the pain and loss to innocent victims — students, law enforcement, families and our community,” Russell’s attorney said in a statement at the time. “In the aftermath of this tragedy, she, her daughter and her family are trying to come to terms with these events.”

After the glare of the media abated somewhat, Russell, with her daughter in tow, moved to New Jersey to live near her late husband’s family. One of those family members, Ailina Tsarnaeva, was accused of threatening the mother of her boyfriend’s child with a bomb, though she denied the allegations.

No charges have ever been levied at Russell, 25, for any involvement in the Boston Marathon attacks, nor has it ever been revealed if she is considered a suspect. However, it is believed that the pressure cooker bombs the Tsarnaev brothers allegedly constructed were put together on the kitchen table in the home Russell shared with Tamerlan Tsarnaev.

Furthermore, “officials had found copies of al-Qaeda’s Inspire magazine and other extremist reading materials on Russell’s computer,” reported The Washington Post.

Dzhokhar Tsarnaev’s trial is currently in the jury selection stage, which is expected to take three to four months to complete.
