Tsarnaev acquaintance killed by FBI unarmed (VIDEO)

Ibragim Todashev was shot six times last week by FBI agents after being questioned about his relationship with Tamerlan Tsarnaev, the late suspected Boston Marathon bomber.

Todashev was reportedly unarmed at the time of his death, and his father says federal investigators shot him in the head — and has the photos to prove it.
