Albert C. Rotz, 72, was shot and killed in his Arlington Avenue home in New Castle, Pennsylvania, on July 13, 2024. That Saturday evening Rotz and his long-time girlfriend, 66-year-old Rebecca Frank, were inside the residence when a relative, 35-year-old Corbin Blake Partin, entered. Neighbors at a pool party next door reported hearing an argument from the house shortly before gunshots were heard.

After a door slammed and a vehicle drove away, Frank emerged from the house wounded and told partygoers that Partin had shot them. First responders found Rotz deceased on the living room floor; Frank was taken to a local hospital. Investigators recovered a percussion cap at the scene, consistent with a black powder or cap and ball weapon, and discovered boxes for two such guns at Partin’s residence, with one firearm missing. Partin, who told investigators he owned a black powder gun but denied involvement, was located at his parents’ home and arrested on two counts of criminal homicide.

Does anyone have information about the events that night or contacts who knew Albert Rotz and Rebecca Frank?
