During the late 1960s and early 1970s, Baggot worked as a portable field camera operator at KABC-TV in Los Angeles. While working at this job, he became involved with the Sharon Tate murder case. On 14 December 1969, the Los Angeles Times printed a confession by Manson "family" member Susan Atkins (aka Sadie), detailing, among other things, how they changed into clean clothes during their getaway drive and then dumped the bloody clothes into a roadside ravine. To their everlasting embarrassment, the Los Angeles Police Department ignored this part of the confession while Baggot and the other members of his news team--reporter Al Wiman and sound man Eddie Baker--did not. The three of them decided to recreate the getaway drive the day after the Times printed the confession. While Wiman drove from Tate's house, down Cielo Drive, then Benedict Canyon Road, Baggot and Baker changed their clothes. When they finished, Wiman parked at the next wide spot on the shoulder. The spot matched the description Atkins gave. At the bottom of the ravine, they found the bloody clothes. At the trial, Baggot testified for the news team because the district attorney's office wanted Wiman to cover the trial as a reporter. Since Atkin's L.A. Times confession was suppressed, no mention of it was made during Baggot's testimony. This made it sound as if he'd found the clothes out of sheer luck. During his self-defense testimony, Charles Manson used this to try to implicate Baggot in the murder. Wiman, Baggot, and Baker are portrayed in Helter Skelter (1976), but are not credited by name. Their names do appear in the book "Helter Skelter.".
