WALTHAM, Mass. (AP) -- Investigators in a Boston suburb are looking into whether there are links between a suspect in last week's Boston Marathon bombing and an unsolved 2011 slaying.
Marathon bombing suspect Tamerlan Tsarnaev, who was pronounced dead early Friday after a shootout with police, was a friend of one of three men found dead in an apartment in Waltham on Sept. 12, 2011, with their necks slit and their bodies reportedly covered with marijuana.
Tsarnaev's friend, Brendan Mess, was also a boxer.

Middlesex County District Attorney's Office spokeswoman MaryBeth Long told The Associated Press on Monday that authorities would check for any connections between the murder and Tsarnaev.
She says it's customary to look for connections between new crimes and unsolved ones.
