On June 21, 1972, 22-year-old Robert Bartone of Delanco was one of six men killed when a visitor opened fire inside the Heritage Office Building at 383 Kings Highway North in Cherry Hill. The building housed Key Personnel, Inc., an employment agency that the attacker, identified as 39-year-old Edwin James Grace, blamed for failing to find him suitable work. Grace arrived from Brooklyn shortly after 2:30 p.m. armed with two sawed-off .22-caliber firearms and numerous magazines.

Witnesses reported he moved through the office, ordering women aside and firing at the men, wounding twelve in all. Officers later found bodies and injured men scattered through the suite; Grace had shot himself and died of his wounds on July 8, 1972. With Grace identified as the lone assailant and no other suspects reported, Bartone’s death was attributed to that attack.

If anyone knew Robert Bartone or was in the Heritage Office Building that day, what details can be shared about him or the scene?
