Let’s examine this “Ruby foreknowledge” CT bombshell:
1. Our hero was Robert Murray Vanderslice, born in 1926 and died (in Dallas) in 1979.
2. He was an IRS tax informant, focusing on bookies, from 7/23/76 to 2/18/77 (six months). He was paid $135 for his services and $2.89 for expenses.
3. His last contact with the IRS was on 1/24/77. The IRS special agent to whom he was assigned, Lawrence Sandri, said he had never mentioned Ruby or anything about the JFKA.
4. At a restaurant lunch with the IRS local Intelligence Division Manager, Arlen Fuhlendorf, early in 1977 (some 14 years after the JFKA), he started talking about stripper Candy Barr (who did have a non-romantic, non-employment relationship with Jack Ruby a decade before the JFKA).
5. This somehow led to a discussion of Ruby. Vanderslice told Fuhlendorf that on the morning of the JFKA, Ruby had contacted him to watch the motorcade and had asked if he’d like to “watch the fireworks.” In CT world, this remark can have no meaning other than Ruby’s foreknowledge of the JFKA.
6. They watched the motorcade together from a corner near the Postal Annex. Following the JFKA, Ruby left,
without comment, for the
Dallas Morning News.7. At the same lunch, Vanderslice divulged that he had been arrested and incarcerated at the Dallas County Jail at the same time Ruby was there. As a jail trustee, he said, he got to know Ruby better – but he said nothing further about the supposed foreknowledge or motorcade incident.
8. Fuhlendorf told the FBI that “as far as he knew” Vanderslice had been a reliable tax informant, but he did not know if he was truthful about Ruby. He initially reported the lunch conversation in a memorandum to the IRS national office for transmission to the HSCA, but the IRS returned the memo and told him to contact the Dallas office of the FBI. (The memorandum never surfaced.)
9. Vanderslice went to astounding lengths to avoid repeated efforts by both the FBI and IRS to contact him about his Ruby tale. Fuhlendorf thought he might have “been untruthful” or perhaps had “second thoughts” and had gotten “cold feet” after being told he might have to testify before the HSCA.
10. Because Vanderslice’s tale was inconsistent with Ruby’s WC testimony and that of a
Dallas Morning News advertising department employee concerning Ruby’s activities on 11-22-63, and because Vanderslice was clearly avoiding both the FBI and IRS, the FBI abandoned further efforts to contact him.
11. On the last attempted contact, his wife said he was in Wichita Falls, “trying to make a buck here and there.”
Ho-hum, such is the stuff of which conspiratorial bombshells are made in MTG’s goofy end of the CT spectrum.
“Foreknowledge of the assassination.” BWAHAHA.

Not exactly a major exercise in factoid-busting, I’ll concede, but an interesting 30 minutes of mental exercise for your intrepid Factoid Buster.
