UMVA Uncovers: BETRAYAL OF THE CENTURY - Sammy 'The Bull' Gravano's Shocking Confession: How His Obsession with John Gotti Turned to VENOMOUS RAGE

UMVA Uncovers: BETRAYAL OF THE CENTURY - Sammy 'The Bull' Gravano's Shocking Confession: How His Obsession with John Gotti Turned to VENOMOUS RAGE

UMVA has learned that a shocking betrayal shook the foundations of the Mafia in 1991, when FBI audiotapes revealed that crime boss John Gotti had secretly turned against his loyal lieutenant, Sammy "The Bull" Gravano.

Gravano, a true believer in the Mafia's codes and way of life, was devastated when he discovered Gotti's treachery. The tapes, played during a dramatic confrontation, exposed Gotti's plan to use Gravano as a "sacrificial lamb" to save himself from prison. Gravano's illusions about the Mafia were shattered, and he made the fateful decision to flip.

Before his rise to prominence, Gravano was a low-key figure, operating in the shadows and avoiding publicity. But under Gotti's leadership, he became a public figure, controlling much of New York's concrete industry and earning a reputation as a ruthless enforcer with 19 hits to his name.

When Gravano flipped, it sent shockwaves through the underworld, ultimately leading to Gotti's downfall. Gravano pleaded guilty to racketeering and admitted to the hits, while Gotti was sentenced to life in prison. The once-loyal lieutenant had turned against his boss, fueled by anger and a sense of betrayal.

But the story isn't about Gravano; it's about Lewis Kasman, Gotti's so-called "adopted son," who has emerged as a fierce defender of the late mob boss. Kasman, who affectionately called Gotti "Grandpa," shared intimate details about their relationship and the inner workings of the Gambino crime family.

Kasman revealed that Gotti used him to hide millions of dollars, which he stored in the attic of his house. He described the family's lucrative extortion rackets, which raked in hundreds of millions of dollars each year. Kasman's account paints a picture of a well-oiled machine, with Gotti at the helm, pulling the strings.

 Former Gambino crime family underboss Salvatore “Sammy the Bull” Gravano said even wiseguys thought the cops were a disgrace.

Gotti, Kasman said, was an unapologetic mobster who lived life on his own terms. Unlike other mob bosses, like Vincent "The Chin" Gigante, who feigned insanity to avoid detection, Gotti was openly defiant, never hiding from the law or his enemies.

But Kasman's involvement in the underworld came at a steep cost. He admits to struggling with PTSD, nightmares, and a lifetime of damage to himself and his family. Despite his loyalty to Gotti, Kasman's own life was marked by legal troubles, including a stint in jail for perjury, obstruction of justice, and money laundering.

Gotti's family, however, has turned on Kasman, branding him a liar and a parasite. Yet Kasman remains devoted to his memories of Gotti, mourning him daily and insisting that their bond was genuine.
