Don't post much but have kept up with this tread. IMO there was only one person there that night and they controlled all three women by training a weapon on one of the three, and by convincing them that this was a robbery- even though that wasn't the true motive. IMO he may have been able to get them into a vehicle under the pretense of heading to an ATM machine or similar ruse with a weapon trained on one of the victims and/or the victims thought they might have a better chance of escape and distraction someplace other than within their house. I believe all of this would fit with Cox being the perpetrator- he moved other victims via vehicle from their original location (and two survivors went along with this and used this as an opportunity to escape).
He also trained a gun on a young girl during a robbery/invasion in order to control multiple people at once.
In addition to the murder of the young woman in Disneyland:

"In August of 1985, a young girl named Kathleen Boice arrived at her house in Crestview California. As she exited her vehicle, Cox, who was following her, jumped from his car, grabbed the victim, threw her to the ground, placed a seven-inch knife to her throat and told her, “Go with me, don’t scream or I’ll kill you.” During this scuffle, the knife cut the victim’s hand. In December of 1985, a young woman, Gidget Wickam, was stationed with the U.S. Army at Fort Ord, California. Ms. Wickam went to the airport to retrieve luggage and, as she was leaving the airport, Cox, who asked her for a ride to the base, confronted her. She complied and, en route, Cox drew a firearm on Ms. Wickham and told her they were not driving to the base but driving to the mountains. "

I'm not convinced that the person who did this is a criminal mastermind. I think he may have military and/or LE training and he got lucky this time, certainly the bodies never being discovered helped keep this unsolved. But I'm betting on Cox even though I doubt at this stage they'd be able to prove it was him barring a confession that leads to remains.
