SAN BERNARDINO  (AP) — San Bernardino police say a man has been found stabbed to death at a cemetery where he apparently had been sleeping.

Authorities say 33-year-old Moises Castrejon Jr. was found Thursday morning on the grass in Pioneer Cemetery.

He'd been stabbed several times.

Authorities believe Castrejon was homeless.

Police say they don't have a motive for the killing and they're asking the public's help in finding the killer.
