On the morning of April 6, 2015, the sound of gunfire alerted neighbors in a Methuen, Massachusetts block. Officers responding to reports at 5 Phillips Street around 10:30 a.m. found 29-year-old Jose Matias-Susana of nearby Lawrence dead at the scene, fatally wounded by multiple gunshots.

The Essex County District Attorney’s Office and the Methuen Police Department opened an investigation and described the death as a homicide while saying they believed the shooting was an isolated event and there was no broader danger to the community. In the days after the discovery, investigators continued working but no arrests had been announced and the inquiry remained active and ongoing.

Did anyone in the area see or hear anything that morning that could help investigators?
