5 Infamous Murder Cases Involving Athletes

Professional athletes become famous for their sporting skills. But some become infamous for the murders they committed.

An Ultimate Fighting Championship mixed martial arts fighter known as “The Beast” is accused of stabbing two of his sisters in Florida and blaming a “higher power” for the attack.

Irwin Rivera, 31, was arrested on Thursday morning at his Boynton Beach home after multiple people called 911 to report a disturbance, according to a Boynton Beach Police Department probable cause affidavit. 

When officers arrived, they found a 22-year-old woman “covered in blood” lying next to the road with stab wounds over her back, head, and arm, according to the affidavit. She told police that her brother had stabbed her and that their sister was still in the house. Inside the home, officers discovered a 33-year-old woman who was also “covered in blood” with stab wounds over her back, face, arms, and hands.

Both victims have been hospitalized, one listed in stable condition and the other in critical condition, the South Florida Sun-Sentinel reports. One of the women suffered two collapsed lungs, ClickOrlando reports.

One of the sisters told investigators that they were visiting their brother and were sleeping in a spare room when they awoke to him stabbing them. Neighbors told police that they woke up to a loud banging sound at their front door. They said they found one of the victims crying, “He’s trying to kill me! Please help my sister.”

Rivera allegedly admitted to stabbing both sisters with a brass knuckle knife. He allegedly uttered "I killed my sisters" to investigators and claimed he attacked them "because it was his purpose, which he was told to by a higher power,” according to the affidavit.

He faces two charges of premeditated murder, according to jail records. It’s unclear if he has a lawyer. 

UFC officials released a statement to MMA Weekly, saying they've received information from Rivera’s management “that he has been exhibiting behavior consistent with mental health issues.”

They noted that Rivera's career is now on hold, pending an investigation into the incident.

“The allegations are extremely troubling and the organization is currently gathering additional information,” they wrote. “The investigation is ongoing and any potential next steps including disciplinary action or medical attention will be determined upon the conclusion. Furthermore, UFC has informed Rivera’s management that he will not be offered a bout at this time.”

Rivera has been a professional mixed martial artist since 2014.
