Kevin Coughlin, who started acting as a kid on Fifties TV series such as CBS’ San Francisco-set family drama, Mama, rests from a ride, in a publicity still from the 1968 teenploitation pic The Young Runaways. That same year Coughlin appeared in the teen rebellion political satire Wild in the Streets and the marijuana melodrama Maryjane. Coughlin died in 1978, at age 30, the victim of a hit-and-run in the San Fernando Valley. R.I.P.
