Feds Stole John Gotti's Brain For Experiments, Claims His Adopted Son

Following real-life Godfather John Gotti's death, sticky-fingered G-men swiped the Italian-American gangster's brain and shipped it to a super-secret facility in Guantánamo Bay, Cuba — for scientific experimentation!

This unsettling allegation comes to RadarOnline.com by way of the Gambino crime family boss' adopted son, Lewis Kasman, 61.

"What do you do with his brain?" a bewildered Kasman asked a supervisory FBI special agent after learning the Teflon Don's noggin had been nabbed by the feds.

"He says, 'We take it to a behavioral science unit at Guantánamo,' " Kasman recalled. "I was just beside myself. I told him, 'You guys are just disgusting. There's no justice. You tortured him!'"

Following Gotti's death from throat cancer at the U.S. Medical Center for Federal Prisoners in Springfield, Mo., on June 10, 2002, Kasman took a specially charted "ambulance jet" to retrieve his body.

"I get a phone call about 10 hours in advance," Kasman said. "Peter Gotti, John's son … he's waiting for me at the airport. He said, 'Lewis, we don't have much time, but I know he would want you here.'"

Upon arrival, Kasman said a local undertaker, who was under contract to the prison, told them "confidentially" about Gotti's missing brain.

Kasman quickly phoned the prison warden, William Hedrick, who informed him: "We got no control over it. The FBI stepped in."

Kasman replied: "You're only the warden in life. You're not the warden in death. That body belongs to the family. You can't touch that body."

However, Hedrick — who confirmed to RadarOnline.com that an autopsy was done "because of the nature of the death" — told Kasman: "I'm sorry you feel that way, Mr. Kasman. He's still in our custody."

At that point, Kasman told RadarOnline.com, he confronted an FBI agent on hand in Missouri to supervise transfer of the body to Gotti's family.

"The FBI supposedly analyzes it," Kasman said. "What are they going to find out? It was just another way to torture the family."

Kasman, who turned Mafia snitch after facing federal racketeering and fraud charges, said he has come forward with this shocking secret because he can no longer support its weight alone.

"It looked like a skull cap cut around the top of the head," he recalled.

"When they closed it, they stapled it with a heavy duty staple gun. He looked terrible. He had no teeth in his mouth."

RadarOnline.com was denied access to Bureau of Prisons documents relating to Gotti's autopsy on grounds that 12 pages of material would put lives in danger.
