He also claimed to be responsible for the DeMeo hit.

And he had laid some charges against Sammy the Bull, that he had contracted kuklinksi to whack someone (forget who). but the fed dropped the charges because Kuklinski was full of shit... And also he died XD

There is no evidence that he ever committed a murder for anyone in the mafia - That was indirectly linked to DeMeo is fact, but that's where the facts end and the mythology starts. Kuklinski was working bootlegging porno movies for DeMeo, but still, no evidence DeMeo ever asked him to whack somebody. besides, if the LCN were to outsource a murder, would they not outsource it o another LCN family?

Most of the people he killed were associates of his own in small time, petty thuggery. I don't know why Kuklinski wanted to make himself out to be some prolific hitman when the evidence suggests he had MAYBE killed 3-4 people tops. All of them his business associates.

Kuklinski has made all kinds of ridiculous claims, most of which don't correlate to any media reports of the time. Such as the HBO doc where he claims to have randomly shot someone in the head with a crossbow on the street... Makes for an interesting story, but there is not one piece of documentation that proves that it actually happened.
