Here is the 2012 story about the 2 guys killed after leaving a Boston bar. Officials said they had no criminal records or connections to gangs.
Basically they went to a bar on a Sunday night, and around 2:00am they were shot waiting at a stoplight:
Both men were fatally shot early Monday, after leaving an undisclosed bar in downtown Boston, accord*ing to their families.
Police say a gray or silver sport utility vehicle with Rhode Island *license plates pulled alongside the BMW sedan Abreu was driving just after 2 a.m. and fired numerous times into the car. Abreu had stopped at a traffic light on *Shawmut Avenue, on the Interstate 90 overpass, and was apparently about to make a left turn onto *Herald Street.

Furtado was in the passenger seat, and three other friends were in the back seat, authorities said. One back-seat passenger was shot three times in the arm, but survived. He was rushed to Tufts Medical Center and was treated and released. The other two occu*pants were unharmed. They ran from the scene, but were later in contact with *authorities, police said.
Based on the article, it sounds to me like something happened at the bar....and they were followed upon leaving the bar by someone who didn't like what they did.
