SAN DIEGO (CNS) - A man was found stabbed to death today in a Chollas Creek-area vacant lot being used as a camp by homeless people.

Working off a tip, police officers responded to the 5000 block of Wightman Street around 9:30 a.m. Thursday. The body was found in a creek bed in overgrown vegetation.

The unidentified victim, a possible transient who appeared to be 30 to 40 years old, evidently had suffered at least one knife wound to his upper body a short distance from where he collapsed on the creek bed and died, Lt. Paul Rorrison said.

Investigators had identified no suspects in the case by mid-afternoon.
