Isaac Kappy was found dead on Monday morning in Arizona. He was 42.
The actor, who had roles in Terminator Salvation, Thor and The Babysitter, died after he "forced himself" off a bridge and was hit by a moving vehicle, an Arizona Department of Public Safety spokesperson told ET.
"On May 13, 2019 at 7:26 a.m., troopers were called to Interstate 40 eastbound at Transwestern Road (milepost 185) for a subject who forced himself off the Transwestern Rd. bridge onto Interstate 40," reads the statement. "He was then struck by a passing car. The man has been identified as 42-year-old Isaac Kappy of Albuquerque, NM. Mr. Kappy died on-scene."
Authorities tell ET that two witnesses stated that they tried to restrain Kappy while on the bridge but he forced his way out of their grasp.
The incident is being investigated as a suicide.
Just prior to his death, Kappy posted a lengthy Instagram message, along with the caption: "Beware the man that has nothing to lose, for he has nothing to protect." This is his only post on the social media service.
"Over the course of the last week, through introspection that should have happened MANY years ago, I have come to some stark revelations about my character. It is a testament to my utter arrogance that these revelations had not come sooner," Kappy wrote in part. "You see, I believed myself to be a good guy. I HAVE NOT been a good guy. In fact, I have been a pretty bad guy throughout my life. I have sold drugs. I have tax delinquencies. I have debts. I have abused my body with cigarettes, drugs and alcohol. I have been abusive to people WHO LOVED ME, including my FAMILY.”
Kappy goes on to claim that he "committed an act so flippantly, without thought, that will become synonymous with short-sightedness and petty, vile greed," but does not go into any further detail.
He does apologize to those friends he has wronged. In 2018, Paris Jackson accused Kappy of choking her at a party they were both attending.
"To the MANY people I have acted abusively towards, I am very, very sorry," he continued. "To my former friends I have used and betrayed, I am sorry. To those I have deceived, I am sorry, although I must say, in my SHEER ARROGANCE, I did not even realize that I had been a bad actor all along."
"I have been lacking in gratitude, humility, honor, service, and proper care for others. I have not honored the light of God within. This lesson has come too late for me, but perhaps it can inspire you," concluded the message. "I will be using the remainder of my time on earth to atone for my transgressions, and to seek the light within, in others and myself."
ET is reaching out to authorities and Kappy's rep.
