The Mod Squad/A Bummer for R.J.
Guest Star: Carl Betz (R.J. Coleman)
While Julie helps her friend search for her missing father, Pete and Linc work a murder case for Greer in which a young girl is the victim. A witness gives a description of the prime suspect, who resembles Julie's friend's father, but with longer hair and sideburns. It turns out that the missing father is the man Pete and Linc are searching for in connection with the murder, a businessman who fell in with hippies trying to recapture his youth, and he in turn is looking for the other man who was present at the murder, who can testify that the gun went off accidentally.
