Forty years ago yesterday, Jimmy Hoffa mysteriously vanished. He was last heard from when he called his wife, Josephine, from a Bloomfield Township, Mich., payphone. He had been stood up at a meeting with two mobsters and was never seen again, according to USA Today.

His disappearance is a mystery that still permeates popular culture to this day.

Most investigators are sure that no one will ever be charged with Hoffa's death, according to USA Today.

However, a mobster believed to have had a hand in Hoffa's disappearance insinuated last year that the FBI were on the right track when it searched for his remains in a New Jersey dump. The mobster died later last year, according to the New York Daily News. Dan Moldea, an investigative reporter, confirmed that the FBI searched said dump in 1975. Hoffa's remains were not found.

Moldea's source was Phillip Moscato, and he had a lot to say, shedding light on this infamous disappearance.

He told Moldea that Hoffa was entombed in a 55-gallon drum and buried at a toxic waste dump under the Pulaski Skyway in Jersey City, N.J. This is the same dumpster FBI agents searched in 1975, according to the Daily Mail. Officials later dug up a farm in Wixom, Mich., where they believed Hoffa had been killed, but Moscato reportedly set the record straight in these interviews.

"Put that to rest," Moscato reportedly said. "I ain't telling you nothing. But I'm telling you that he (Hoffa) ain't (at the farm)," he said, according to the Daily News.

Hoffa was declared legally dead in 1982. Many believe his death was the result of a Mafia hit due to his refusal to back down from a fight to regain the presidency of the Teamsters Union, according to the Daily News
