Link sought between brother, 3 Waltham killings

It was one of the most gruesome killings in Greater Boston in many years: three young men found with their throats slit inside a Waltham apartment on a quiet residential street, their bodies sprinkled with marijuana.

Now, police and prosecutors are stepping up their investigation into the unsolved 2011 triple homicide at the request of victims’ relatives who believe that suspected Marathon bomber Tamerlan Tsarnaev may have played a role, noting that Tsarnaev had been close friends with one of the dead men.
