The investigation began when police got a call just before 8 p.m. Sunday about a man lying on the ground along Tally-Ho Drive.
When officers arrived, they found Wolfgang Joppich unconscious. He was taken to Cape Fear Valley Medical Center where he was declared dead.
His wallet and other personal belongings were later found in a dumpster nearby on Pedro Drive.
Joppich was known to frequent the Bragg Boulevard area to feed feral cats. Police said they're having difficulty locating his next of kin.
