Whatever Happened To Michael Fennell? (Calvin)

He played Calvin in Carwash,he talked some junk in that movie. When they thought he was hit by a car.He said,I made you look and stuck out his tongue.His mama slapped him across the head and said,Boy you better watch where you're going?I think he had a uncredited part in the movie Colors or South Central.It was maybe about 10 seconds long.I wonder whatever happened to him.
