Richard Duncan, 73, was shot and killed on his front porch on the 1700 block of Prospect Avenue in Abington, Pennsylvania, shortly after 2 p.m. on December 23, 2015. He was a longtime volunteer with the local VFW in Willow Grove and active with community programs.

Authorities say the suspect, identified as 72-year-old Leroy Clark, was a fellow volunteer with Toys for Tots. The shooting followed a dispute over allegations that Clark was withholding toys in exchange for sexual favors; Clark confronted Duncan with those accusations, then returned the next day and shot Duncan twice. Clark fled but was later located by police; he shot himself during the confrontation and was hospitalized. Two handguns were recovered from Clark’s car. Family members described shock and heartbreak over Duncan’s death.

Does anyone who knew Richard or the local volunteer programs have information that could help clarify what happened?
