Sheriff's deputies say ground crews found the wreckage of a small plane and fragmented human remains in steep, mountainous terrain, after a sheriff's air patrol spotted debris.
Investigators believe the pilot was 24-year-old Daniel Katz. Katz was a Mexico City resident who was flying a Piper Archer from La Verne to Riverside in June, 2001, but was never heard from again.
The remains have not been positively identified.
