PITTSBURGH — More than 100 people gathered Saturday at a service for a mother of five who was among those killed in gunfire at a cookout.

They paid their respects at Mulberry Community Church in Wilkinsburg to Tina Shelton, 37, who was killed in the March 9 gunfire in the same town that left five adults and an unborn child dead.

Investigators said one man fired a pistol from an alley at the backyard gathering, prompting the cookout guests to run toward a house, where they were gunned down by another man with an assault rifle.
