Officials in San Diego say a homeless man struck multiple times in the head with a skateboard has been placed on life support.
Police on Sunday are searching for a male suspect in what investigators say was an unprovoked attack on the man who was sleeping in an alley.
The 55-year-old victim was hospitalized with serious head trauma following the assault before dawn Saturday in the North Park neighborhood.
Witnesses tell police they saw the suspect drive off in a white Honda. He is described as a white male in his late teens to early 20s, about six feet tall.
