Authorities were excavating a grave site Wednesday in unincorporated Victorville after finding multiple sets of human remains in a deserted area.
A motorcyclist stumbled upon the first set of remains Monday morning in the desert area between Quarry Road and the 15 Freeway, according to the San Bernardino County Sheriff's Department.
Coroner's officials confirmed the remains were human and returned with homicide investigators Tuesday to continue the investigation.
Now, "investigators believe they have located the remains of more than one person," the Sheriff's Department said, adding that it appears the remains have been there for some time.
The investigation remained ongoing as crews excavated the site to determine if there were any more remains.
