Former UFC Star BJ Penn Makes Wildly Outrageous Claim That His Family Was Killed And Replaced By Imposters

BJ Penn

In a shocking series of social media posts, former UFC champion BJ Penn has claimed that his family members have been murdered and replaced by imposters. The 46-year-old fighter, known for his success in the octagon and fiery personality, is now pleading with police in Hawaii to launch an investigation into what he describes as a bizarre and sinister conspiracy.

Penn took to Instagram with emotional messages, insisting his mother, Lorraine Shin, and brothers Jay Dee, Reagan, and Kalani Mamazuka are no longer who they claim to be. “My mother… my brothers… we’re all murdered and I need you to investigate,” he wrote. He also warned that if he harms the people currently living as his family, he will face legal consequences, while if they harm him, “nothing will happen to them.”

‘Fake Frauds’ And A Cry For Help

The UFC Hall of Famer, who held titles in both the lightweight and welterweight divisions, says the people around him are imposters trying to steal his family’s identity and assets. “Get these people out of my house and off my properties,” he pleaded to the Hilo Police Department.

BJ Penn didn’t stop at general claims. He shared side-by-side photos of what he says are his “real” brother JD and a “fake JD,” pointing out what he claims are physical differences such as “brown eyes,” a “crooked front tooth,” “hair plugs,” and a “Jay Leno chin.”

Authorities have not confirmed any official investigation despite the serious nature of the allegations. Authorities have yet to release any statement responding to Penn’s requests. His posts have sparked widespread concern, especially among longtime fans and MMA insiders.

Critics online have questioned the mental state of the retired fighter, who hasn’t competed professionally since 2019. Penn addressed those remarks directly in a fiery follow-up post: “It’s the stealing and the killing that must stop. F*** you and your horse. A nation of laws or a nation of flaws?”

Penn, once celebrated as one of MMA’s most gifted talents, now finds himself at the center of a disturbing story far outside the cage. The situation has drawn national attention and deep concern, though authorities have yet to take legal action based on his claims.
