De’Andre Barboza was 16 when he was shot in Dorchester’s Codman Square area on December 1, 2008, the day before his 17th birthday. He was standing at the corner of Lyndhurst and Washington streets when someone shot him multiple times; he was taken to Boston Medical Center with a fatal gunshot wound to the head and died of his injuries on December 3, 2008.

Investigators say the shooting followed a dispute the previous day between De’Andre and another young man. Witnesses reported that after De’Andre fell from the initial shots, the shooter fired additional rounds, hitting his legs and delivering the fatal head wound. Patrick Grier, then 21, was identified as the shooter, arrested and charged with murder; a jury convicted him of first-degree murder and he was sentenced to life without parole.

Does anyone who knew De’Andre or who witnessed the events around Lyndhurst and Washington streets on or around December 1, 2008 have information to share?
