It would be helpful to know if Robin had her wisdom teeth or not, if hers had been extracted that would basically rule her out as Granada Hills Jane Doe.
Her dentals are available according to Doe Network, I don't believe the charts are publicly available though due to privacy concerns.
I think it's HIPAA related, the same reason why dental chart details are no longer displayed via NamUs for UIDs or the missing.
Mona Gallegos lived out this way her case is similar http://www.zodiackillersite.com/viewtopic.php?f=20&t=1758
I think you're on to something. Under circumstances: "A major brush fire had gone thru this are during Sept. 1970, and there have been heavy rains and an earthquake since that time." Robin disappearing in Nov. 1970 fits right in with that time frame.
For some reason, I just can't dismiss Bruce Davis as a suspect. He was identified as the guy who picked Robin up as an eyewitness. I don't think he was Zodiac, but he may have himself been a serial killer, separate from the Manson Family.
Never heard of this case at all, however with looking at the UID and the new Namus search tool, this UID produced Robin Graham, doesn't have her ruled out and according to Mapquest is a half hour away from where she was last seen only thing off what year of death but was skeletonized . .. feedback?

Robin Graham disappearance: A chilling Hollywood mystery 4 Nov, 2018 "When Robin Graham's Dodge ran out of petrol on the Hollywood Freeway early on a Sunday morning, she'd been driving for less than minutes. Graham had been out partying all night with a group of college friends and had gotten a lift to her car, which was parked at her workplace. Her car stalled near the Santa Monica Boulevard off-ramp. Steering to the side of the road, she was helped moments later by California Highway Patrol officers, who offered to call her a tow truck. Declining the offer, she instead walked to a nearby call box and phoned home. The patrol car did a loop and stopped again as she returned to her vehicle. She informed the officers she had successfully called to be picked up and so they left her by the side of the road, reports news.com.au. When the Highway Patrol officers drove past for the third time that night, about 2pm, they noticed Graham talking to a man, who they assumed to be the family member she mentioned calling. A light blue Corvette was parked nearby; the officers kept driving. This was the last time Robin Graham was seen alive.... Granted, it's not much to go on, but until Robin Graham's body is found, she will remain one of numerous young people who went out one night in California, and never made it home again."
