(Business Insider) On Sept. 11, 2011, three men were found in a Boston-area apartment with their throats slit and their bodies covered in marijuana.
Tamerlan described one of the murder victims, 25-year-old Brendan Mess, as his best friend. He and Mess were once roommates and boxed together.
The two others who died were 31-year-old Erik Weissman and 37-year-old Raphael Teken, both of Cambridge.
Since the bombings, people have been speculating that Dzhokhar and Tamerlan Tsarnaev — the two brothers suspected of the Boston marathon bombing attack that killed three people and injured about 260 others — were tied to the killings.
