Irwin Rivera, a 31-year-old Ultimate Fighting Championship fighter known as 'The Beast', has been arrested and charged with two counts of premeditated attempted murder after allegedly stabbing his two sisters in their sleep at his Boynton Beach, Florida apartment early Thursday morning.
According to an arrest report, Rivera told investigators he attacked his sisters because a 'higher power' instructed him it was his 'purpose'. The victims, aged 22 and 33, had been visiting Rivera and were staying in a spare bedroom. They awoke to find him repeatedly stabbing them with a brass knuckle knife.
The younger sister managed to escape and was found by neighbours covered in blood, begging for help. She sustained multiple stab wounds to her back, head and arm. The older sister was found inside with multiple stab wounds and two collapsed lungs; she was taken to Delray Medical Center in critical condition. The younger sister is in stable condition.
Rivera fled the scene but was apprehended by Delray Beach Police around 7am. He spontaneously told officers, 'I killed my sisters', and later admitted to the stabbings in a statement. The UFC released a statement saying Rivera's management reported he had been exhibiting behaviour consistent with mental health issues, and his career is on hold pending investigation.
