The only son of U-S comedian Bill Cosby was shot to death alongside a California freeway on Thursday, apparently as he stopped to change a flat tire on his Mercedes- Benz convertible.
Police say the body of 27 year old Ennis Cosby was found next to his dark green car by a driver who stopped to help.
Los Angeles police say 27 year old Ennis Cosby was shot as he tried to change a tire near an off-ramp of the San Diego Freeway on Thursday.
Cosby - who is the son of the comedian Bill Cosby, died of a single gunshot wound.
His body was found next to his dark green Mercedes-Benz convertible.
KCBS, a Los Angeles television station, is reporting that Cosby was on his way to see a woman friend when he called her by cellular phone to say he had a flat.
He apparently asked her to come to the spot where he pulled over so she could help illuminate the area.
She arrived shortly after the shooting, calling police, the T-V station reported.
Police say robbery may have been the motive, and they are looking for a white male suspect.
Authorities are basing this on the woman's description of the scene.
Cosby who was a doctoral student at Columbia University's Teachers College in New York, was on winter holiday.

Cosby and his wife, Camille, also have four daughters.
"Mr Cosby and Mrs Cosby are extremely upset. Needless to say, losing a child is one of the most severe things to happen to anybody, and they are in significant grief. But he's asked us to go forward and do everything we can to locate the suspects, and we intend to do that."
