Man Sentenced for Gun Used by Boston Marathon Bombers to Kill MIT Officer Sean Collier

A man who pleaded guilty to possessing the illegal gun eventually used by the Tsarnaev brothers to kill MIT Police Officer Sean Collier has been sentenced.

Merhawi Berhe, 22, faces six months in prison and two years of supervised release. He pleaded guilty back in March to possession of a firearm that had its serial number obliterated.

Berhe transferred the gun to another person, who transferred it to Stephen Silva, who transferred it to Dzhokhar Tsarnaev.

Dzhokhar and his older brother, Tamerlan, set off improvised explosive devices at the Boston Marathon on April 15, 2013, killing three people and injuring many more. They went on to kill Collier during the manhunt that followed.
