However Jack Webb stretched the truth a wee bit with this one. The story is based on the case of Harry Glatman who murdered 2 aspiring models and one woman he met through a lonely hearts club over the course of 1957-58. The police weren't hot on his trail and were just working it as a missing persons case. Nor was he cornered on a rainy hillside with his 4th victim inside a trailer. Instead, he got into a struggle with his 4th intended victim on the side of a Orange County highway and was arrested after a passing CHP motorman, on his way home, stopped to investigate. Glatman confessed to the 3 murders and Orange County notified the LAPD since 2 of the victims were from LA and Sgt.Pierce Brooks was assigned the case to clean up their end. Still it's a pretty good Dragnet episode.
