GRESHAM, Ore. (AP) — Gresham police are investigating after multiple people were wounded by gunfire at a vigil for another man who was fatally shot over the weekend. Police say they arrested 21-year-old Omar Cibrian Gongora in Sunday’s shooting death of 22-year-old Alejandro Barajas. Police say mourners were gathered for a vigil for Barajas on Monday when a car drove by slowly and members of the crowd exchanged gunfire with those in the car. No arrests have been made. Seven people were injured. Multnomah County District Attorney Mike Schmidt is asking for the community’s help making arrests in the case.
