The ethnic Chechen brothers Dzhokhar and Tamerlan Tsarnaev, who are accused of carrying out the Boston Marathon bombing, allegedly returned to their family's Cambridge, Massachusetts, apartment to gather weapons after the FBI released photos of the duo three days after the attack, prosecutors said on Tuesday, Reuters reported.
The brothers are also accused of shooting a Massachusetts Institute of Technology police officer the night of April 18, 2013, after U.S. officials released photos, according to court papers filed in U.S. District Court in Boston, according to Reuters. The bombing killed three people and injured 264.
"Almost immediately, (Dzhokhar) Tsarnaev left UMass-Dartmouth, drove back to Cambridge, and met his brother at the Norfolk Street apartment, where they collected a small arsenal of weapons, including at least six bombs, a handgun and other weapons, and then embarked on a murderous crime spree," federal prosecutors said in a court filing, Reuters reported.
Prosecutors are arguing against a bid by defense attorneys to have evidence found in the search of that apartment thrown during the upcoming trial, according to Reuters.
Prosecutors say the brothers killed the MIT police officer and engaged in a gun battle with police in the Boston suburb of Watertown, Massachusetts, that ended with 26-year-old Tamerlan dead, Reuters reported.
Dzhokhar briefly escaped and was captured the following evening and is now 20 year-old while awaiting trial, according to Reuters. He faces the risk of execution if convicted of carrying out the largest mass-casualty attack on U.S. soil since the Sept. 11, 2001 attacks on New York and Washington.
