As hundreds of mourners sat in Greater Love Tabernacle Church in Dorchester yesterday morning for the funeral of shooting victim Andre Stoner, word spread through the church that Stoner’s cousin had been found hours earlier in a nearby elementary school parking lot, dead of a gunshot wound to the head.

Now the congregation in this neighborhood beset by crime had two victims to mourn. Relatives screamed and ran toward the back of the church, confused mourners ducked into their seats, and white-gloved ushers tried to bring the chaos under control, but Stoner’s funeral had already been overtaken by a new round of grief for Nicholas Copeland, 20.
