Breaking news: I just learned something wild about Robert Maheu, the person who I believe was Ron Tammen’s informant

I have a big announcement. Robert Maheu, the man who I believe was informant LV 366-PC for the FBI, and the man who I also believe informed them about Ron Tammen’s whereabouts in 1973, lived in Tucson, Arizona, during 1960 and 1961, and possibly a little longer. I know this through several ways, the most compelling of which is that his oldest son Peter had graduated from Salpointe Catholic High School in Tucson in 1961. Unlike his two younger brothers, Peter frequently showed up in news articles in the Tucson Daily Citizen throughout his senior year. 

This is a very big deal.

As you may recall, in 1970, LV 366-PC had informed the FBI about Marty Fenster, who had been managing the Grace Ranch in Tucson for mobster Pete Licavoli. The informant let the FBI know that Marty was now working for the Clark County Vending Company in Las Vegas under Frank Milano. 

In a follow-up post, I shared that Robert Maheu could have encountered Marty Fenster at the Frontier Hotel, a Howard Hughes–owned property where the Clark County Vending Company ostensibly had a contract. Maheu’s office was in the Frontier Hotel. That could be how he knew about Marty’s whereabouts in 1970.

This new discovery is much bigger. I think it’s now safe to surmise that, with Maheu living in Tucson during 1960 and 1961, it’s entirely likely that he became acquainted with Pete Licavoli, Grace Ranch, and perhaps even Marty Fenster at that time. 

Chauncey Holt, author of “Self-Portrait of a Scoundrel,” who had CIA and Mob ties, had said that Pete Licavoli was friends with John Roselli and Sam Giancana. Robert Maheu was friends with Roselli and Giancana too, and, in 1960, he’d just begun working with them on a Castro assassination plot.

Holt also said that Licavoli and others were conducting training at Grace Ranch for Operation Mongoose, one of the CIA’s Castro assassination plots. So, if Holt is to be believed, at roughly the same time that the CIA and Mafia were conducting their trainings at Grace Ranch for the assassination of Fidel Castro, Robert Maheu, who was also working with the CIA and Mafia to assassinate Castro, was living in a gorgeous house in the Catalina foothills only about 12 miles away. 

I’m no gambler, but I’d say the odds of this happening without them bumping into one another would be pretty high.

  1. Wow! You go, girl! Mahue was not only potentially connected to the Licavoli Grace Ranch where Holt said JFK assassins trained, but, according to the incomparable researcher, Lisa Pease, in her book A Lie to Big to Fail, Mahue has a connection to the hypnosis/set up of Sirhan Sirhan and assassination of RFK (to be clear, IMO, Sirhan, like LHO, didn’t shoot ANYONE! They were both patsies). From WAPO article:

    “In her book A Lie Too Big to Fail, researcher Lisa Pease connected CIA operative Robert Maheu to Sirhan Sirhan’s hypnosis by outlining Maheu’s ties to the CIA’s mind control projects. Pease theorized that Maheu may have been the link who introduced a handler—referred to by Sirhan as “Radio Man”—to the plot.

    I apologize in advance if you have already made this connection – I haven’t been on your site in AGES and am way behind in reading your posts, but your Mahue/Tammen article really caught my attention! Keep up the great work!

    1. Thank you! I’d mentioned Lisa Pease’s finding in one of my “informant” posts, but I probably didn’t state its significance as well as you have here. 😊 Robert Maheu may be the one guy who brings all of these various players together. I do believe he could be the linchpin in the Tammen story. I’ve reached out to Lisa in the past and she’s really great. Once I feel I have my evidence all sewn up, I plan to reach out again. I think she’ll be interested to know that my research has separately led me to Maheu too.
