Authorities put out a public call Friday to anyone who might be able to help investigators determine what led to the death of a man whose skeletal remains were found in Alpine in 2012, about 15 years after he went missing.
Christopher Schafer, then 28, was last seen by his family in El Cajon in August 1997, according to the San Diego County Sheriff's Department.
Two years ago, genetic DNA comparisons allowed investigators to identify human remains that had been found in Sloane Canyon a decade earlier as those of Schafer, sheriff's Detective Jessica Kuehn said.
Officials have not disclosed whether Schafer's cause of death has been determined.
