UFC Fighter Arrested For Stabbing His 2 Sleeping Sisters: Police

BOYNTON BEACH, FL — Ultimate Fighting Championship fighter Irwin Rivera was arrested Thursday morning for stabbing his two sisters, who were asleep at the time of the attack, according to a Boynton Beach police report.

The 31-year-old professional mixed martial arts fighter faces two counts of attempted murder.

Police were called to Rivera’s Boynton Beach home, which his 22- and 33-year-old sisters were visiting, just after 3 a.m. Thursday, according to the report. His sisters’ names weren’t identified in the report.

The UFC fighter fled when police were called. When they found him around 7 a.m., he told them, “I killed my sisters.”

Later, during his sworn taped interview, he told police that he stabbed his sisters with a brass knuckle knife and believed he had killed them. He stabbed them “because it was his purpose” and “a higher power” told him to do so, he told police.

Both women were brought to the Delray Medical Center for treatment. The younger sister suffered from two collapsed lungs, while the other had multiple wounds throughout her back, face, arms and hands.
