Tsarnaev Tied to Triple Homicide

In an added twist to the Boston Marathon bombings, prosecutors now say another man tied to the brothers told investigators that Tamerlan Tsarnaev was involved in a 2011 triple homicide that included a friend of his among the victims. The information was gleaned from the record of an interview with Ibragim Todashev, who was fatally shot at his Orlando home after allegedly turning violent during questioning with the FBI and two Massachusetts state troopers. The information became public knowledge Monday after lawyers for Tsarnaev's surviving brother, Dzhokhar, sued for access to documents relating to the case.
