The story of Robert Prongay gets more confusing the more anyone retells it, but it all begins with prolific serial killer and alleged mafia hitman, Richard Kuklinski. Known as “The Iceman” for masking his victims’ times of death by freezing their corpses, Kuklinski claimed to have killed more than 100 people for the five families of the New York City mafia — and he claimed to have learned his skills from a Special Forces veteran.
Kuklinski was only ever convicted of five murders, but it was enough to put him away for the rest of his days. These victims were small-time drug and porn dealers in the mid-1980s. In one of those murders, he used a hamburger laced with cyanide, a murder technique he picked up from a man he described as a Special Force veteran-turned-ice cream man, Robert Prongay.
“He taught me a lot,” Kuklinski once said. “But he was extremely crazy… he’d go into these neighborhoods and sell ice cream to the kids, then maybe kill one of their fathers.“
Kuklinski was known as “The Iceman” to law enforcement and Prongay was called “Mister Softee.” According to Kuklinski, the two men met at a New Jersey motel while stalking the same mark. They summed each other up and realized they were both contract killers. Prongay told Kuklinski he was an Army Special Forces veteran, trained in using explosives and poisons.
In Kuklinski’s words, Prongay used his ice cream truck as a surveillance van to follow around his potential victims, whom he would kill using aerosol cyanide and remotely-detonated grenades. It was from Prongay that Kuklinski said he learned to freeze bodies to mask time of death.
Not much is really known about the real Prongay. Kuklinski claimed to have a very firm moral code when it came to killing. He could kill anyone without feeling anything at all, but he wouldn’t kill innocent women and children. The Iceman claimed that Mister Softee asked Kuklinski to kill his wife and young son for him, which Kuklinski declined. When Prongay began to talk about poisoning an entire reservoir just to kill one family, Kuklinski shot him.
The only verification that Prongay existed and may have known Kuklinski is that an ice-cream man by the name of Robert Prongay was killed in his ice cream truck, shot twice in the chest. On Aug. 9, 1984, his body was found hanging out the side of his ice cream truck. The real Prongay, it turns out, was facing trial in New Jersey for bombing the front house ex-wife and making terrorist threats against his ex-wife and son.
Before murdering Prongay, the Iceman and Mister Softee teamed up on a few occasions. An HBO Documentary in 2001 found old film reels of Prongay and called him an “Army demolitions expert,” a claim verified by Paul Smith of the New Jersey Organize Crime Bureau.
“It is our opinion,” Smith told HBO, “that friendship led to Richard Kuklinski learning a lot about killing with different types of chemicals, including cyanide.”
In reality, Kuklinski made a lot of claims about himself and his famous hits. He was convicted of killing the members of a small-time burglary gang he led in New Jersey, along with one of his cyanide suppliers. The claims of the people he worked for and murdered makes his resume sound like one of the most prolific hitmen in the history of the American mafia. If you believe Kuklinski, he was recruited by Gambino capo Roy DeMeo, who gave Kuklinski his death orders.
Kuklinski claimed the murder of NYPD detective Peter Calabro, a murder in which Gambino underboss Sammy “The Bull” Gravano was also charged. The Iceman also claimed the death of Roy DeMeo and claimed to be involved in John Gotti’s famous hit on Gambino boss Paul Castellano. The only mafia hit law enforcement really related to Kuklinski was that of Calabro.
Kuklinski claimed to have killed some 100-250 people between 1948 and 1986 but his claims varied wildly in later years, as some of them were unverifiable and others were found to be complete fabrications (he claimed to have killed famous disappearing act Jimmy Hoffa, for example). Renowned mafia writers and historians claim to never have heard of a hitman named Kuklinski.
If Kuklinski’s claims are true, he would be the most prolific serial killer/hitman in American history.
