HARRISBURG, Pa. (WHTM) – The death of a Susquehanna Township police officer earlier this year resulted from injuries he sustained in a gunfight with a bank robber 38 years ago, authorities said Wednesday.

Sgt. Robert “Bo” McCallister responded to an alarm at the Fulton Bank on North Progress Avenue and Nationwide Drive and was shot on Feb. 19, 1981. He was 69 years old when he died Jan. 20. 

His death has been ruled a homicide.

“Just because great physicians and other medical personnel were able to keep him alive, it does not excuse the person who inflicted that wound,” Dauphin County District Attorney Fran Chardo said.

No one was ever arrested for shooting McCallister. Police say they have leads and a suspect, but they did not identify that person.

McCallister had 32 years of police service before retiring as a lieutenant for Susquehanna Township. He was the youngest officer ever promoted to the rank of sergeant in the township’s history and its first-ever recipient of the Medal of Valor and the Purple Heart Medal, according to his obituary.

The Dauphin County uniformed officer of the year award is named in his honor.
