The Former UFC Star Appears To Threaten Violence

In Instagram videos, Penn named his mother Lorraine Shin, his brother Jay Dee Penn, Reagan Penn, and Kalani Mamazuka, claiming all four had been murdered and that the people currently in his home are imposters. As evidence, Penn posted a side-by-side photo of his brother and mother’s ears, insisting they looked different than those of his real family members. He also cited his brother’s freckles as a supposed sign that he had been cloned.

“These guys aren’t my real family,” Penn said in the video. “Look at their ears. Look at the freckles. I want DNA tests.” His message was directed to local authorities, urging them to investigate and remove the alleged imposters from his property. The accusations, lacking any credible evidence, have been widely dismissed by fans as troubling signs of a possible mental health crisis.

He also threatened to use violence against his family members, writing, “If I harm any of these people that are acting like my mom or my brothers, I go to jail and lose everything. If they harm me, nothing will happen to them and I lose everything.. I have many black belts over the years that are police officers. Are you guys gonna help me? Are we going to help Jd and Reagan and my mother and look for them and investigate these fake frauds who are trying to steal everything from my family? #hawaii”
