Nicholas Trotman, 38, was shot and killed in the early morning hours of June 29, 2011, on Olney Street in Dorchester. Officers responding just after 1:40 a.m. found him suffering from a gunshot wound outside 45 Olney Street; he was pronounced dead at the scene and the medical examiner classified the death as a homicide. Early reports described neighbors hearing multiple shots and one account said the fatal wound was to the head.

Police canvassed the area and appealed for information. A mid-July update said witnesses had heard an argument before the gunfire and investigators were exploring whether the killing might be gang-related, but no suspect description or arrest was released. The case remained listed among Boston’s unsolved 2011 homicides.

Did anyone in Dorchester hear or see anything that night, or have information about activity on Olney Street around 1:40 a.m. on June 29, 2011?
