A few weeks earlier Tamerlan Tsarnaev had gone to a fireworks store in New Hampshire and bought 48 mortar shells, also used in the bombs. At the fireworks store, Tamerlan had asked for the “biggest and loudest” fireworks available and spent roughly $200, according to court documents.
“To live in a small apartment and buy five pressure cookers and have all those explosives obviously just does not make sense – something other than cooking was going on,” said former FBI special agent and ABC News consultant Brad Garrett.
Lawyers for Russell and federal prosecutors initially declined to answer ABC News questions about Russell’s status, but a senior law enforcement official said she could face charges of misprision of a felony, or failing to notify authorities of a crime about to happen.
Following Tuesday’s ABC News report on Russell, an attorney for Russell, Joshua Dratel, said in a written statement to ABC News, “There is no video of Ms. Russell at a Macy’s in connection with the purchase of pressure cookers, and any claim that there is such a video, or any claim remotely approaching that, is false. Also false is any allegation that Ms. Russell was involved in the purchase of any pressure cookers, or that she accompanied her late husband with respect to any such purchase by him.”
Tamerlan Tsarnaev was killed in a police shootout three days after prosecutors say he and his younger brother, Dzhokhar Tsarnaev, detonated twin bombs near the finish line of the Boston Marathon, killing three people – including an eight-year-old boy – and injuring some 260 others.
Days after Tamerlan was identified as one of the suspected bombers, another of Russell’s attorneys at the time, released a statement saying Russell was assisting the investigation into the bombing and was not aware of the plot beforehand.
“As a mother, a sister, a daughter, a wife, Katie deeply mourns the pain and loss to innocent victims, students, law enforcement officers, families and our community,” the attorney, Miriam Weizenbaum, said then.
Shortly after the bombing, Russell left her family and moved to New Jersey to live with Tsarnaev’s two sisters. She later moved out of her sister-in-law’s apartment and was last seen in a transitional housing facility for the homeless in New Jersey, according to authorities briefed on the investigation. Authorities told ABC News the FBI put Russell under surveillance during last year’s Boston Marathon race.
Opening statements in the murder trial of Dzhokhar Tsarnaev are set to begin Wednesday morning. Russell is not expected to be called as a witness for the government.
