▶ Watch Video: Lake Mead’s low water level prompts feds to consider declaration of Colorado River water shortage

Mobsters who end up sleeping with the fishes are usually never seen again.  

But climate change has a way of messing even with the mafia, and a watery grave outside Las Vegas is starting to cough up Sin City’s darkest secrets.

Lake Mead, which can be reached from the Las Vegas Strip by a short ride in the trunk of a car with your hands and feet bound, is drying up in a grueling decades-long drought.

Its receding waters are leaving behind the usual flotsam and jetsam of a lake heavily trafficked by weekend boaters — and even exposing a ship dating back to World War II.

But the receding waters are also revealing bodies.

One particular find caught the attention of mob-watchers: the skeletal remains of a man who had been shot in the head, stuffed in a barrel and tossed in the lake four decades ago.

“The mob had a propensity to put people in barrels, whether they’re burying them in a lake, or dumping them out in the field,” said Geoff Schumacher of The Mob Museum in Las Vegas. “That’s number one. Number two, the person was shot in the head, typical mob hit style. And third, we know that this happened in the late ’70s, early ’80s (when) the mob was very prominent in Las Vegas.”

Las Vegas police are still investigating the body found in the barrel at Lake Mead, and in response to AFP inquiries would only say there is an ongoing probe. Last month, the FBI confirmed to the Las Vegas Review-Journal that the agency is involved in investigating the death.

The Las Vegas Justice League told the newspaper that it donated $5,000 to a lab in an effort to identify the man through DNA testing.

Schumacher has his theories about the identity of the dead man.

One suggestion is that he was Jay Vandermark, who worked at the Stardust Hotel, an operation run by Frank “Lefty” Rosenthal on behalf of the Chicago Mob.

Rosenthal — who was played by Robert De Niro in the movie “Casino” — was funneling cash back to his bosses, until the scheme drew the attention of local authorities.

Vandermark disappeared shortly thereafter.

A more likely candidate for the body in the barrel, Schumacher said, is a man named Harry Pappas who was also connected to the Chicago Mob.

“One of the extra perks for visitors to Las Vegas, if you were a high roller … was they would take you out on the boat at Lake Mead,” Schumacher said. “The Stardust had a boat out there and Harry Pappas was in charge of that whole operation. Right before he disappeared, he told his wife he was going to lunch with someone who was interested in buying his boat. We’ve never seen Harry Pappas again.”

“These guys were cold-blooded killers”

An improbable oasis of hotels, casinos and vice sprouted in the baking Nevada desert in the 20th century.

Las Vegas had been founded in 1905, but it wasn’t until work began on the nearby Hoover Dam in the 1930s that its population swelled.

The influx of construction workers — mostly single men — created a market for entertainment, which was filled by sex workers, showgirls and legalized gambling.

And where there is flesh, casinos and booze, organized crime is lurking in the background.

“The mob played a pretty big role in the development of Las Vegas from the 1940s through the 1980s,” said Schumacher.

“There was a lot of behind-the-scenes activity where the mob was controlling the management of the casinos, but also building and expanding the casinos, using in many cases, Teamsters union money.”

The city grew rich in the post-World War II boom that fueled the American dream, becoming the global capital of gambling.

And for every $100 that a hapless tourist lost at the blackjack table in a haze of free booze, a mafia boss in Chicago or New York wanted his cut.

“The reality was that these guys were cold-blooded killers; they were thieves. If you were to cross the mob in some way … there definitely were consequences,” Schumacher said.

Lake Mead is a massive reservoir on the Colorado River created by the Hoover Dam. It is now just a quarter full — the result of a drought and warming temperatures fueled by man-made climate change — and shows no sign of stabilizing.

In May, two sisters from suburban Henderson who were paddle boarding on the lake near a former marina resort discovered a human jaw with teeth. They called park rangers, and the National Park Service confirmed in a statement that the bones were human.

As its shoreline retreats, revealing more of the lake bed, it may yield more mob secrets, said Schumacher.

“I don’t know if we find another body in a barrel, but I have to believe that there could very well be a second murder victim out there,” he said.

At least one former official with long ties to Vegas agrees.

“There’s no telling what we’ll find in Lake Mead,” former Las Vegas Mayor Oscar Goodman said in May. “It’s not a bad place to dump a body.”

Goodman, as a lawyer, represented mob figures including the ill-fated Anthony “Tony the Ant” Spilotro before serving three terms as a martini-toting mayor making public appearances with a showgirl on each arm.

“I’m relatively sure it was not Jimmy Hoffa,” he laughed. But he added that a lot of his former clients seemed interested in “climate control” — mob speak for keeping the lake level up and bodies down in their watery graves.

A sunken World War II-Era Higgins landing craft that used to be nearly 200 feet underwater is being revealed near the Lake Mead Marina as the waterline continues to lower on July 1, 2022, in the Lake Mead National Recreation Area in Nevada. The water level at Lake Mead is at its lowest since being filled in 1937 after the construction of the Hoover Dam.
