'Thor' and 'Terminator: Salvation' actor Isaac Kappy has been confirmed as the man who jumped to his death from a bridge in Arizona on Monday, according to TMZ.

Officials confirmed on Tuesday that Kappy, 42, was struck by a Ford pickup truck after hurling himself from the Transwestern Road bridge onto Interstate 40, where he died, according a statement from Bart Graves, a spokesperson for the Arizona Department of Public Safety.

In the 24 hours leading up to his death, Kappy posted a long statement on Instagram where he wrote, 'I have not been a good guy,' and 'I have been abusive to people who loved me.'

The self-admitted drug user made headlines in 2018 for allegedly assaulting Michael Jackson's daughter, Paris, by choking her 'during a game night party.'

The native Angeleno has also publicly accused Seth Green of being a pedophile.

Arizona state troopers were called to the scene at 7.26am Mountain on Monday, and Kappy was found deceased upon their arrival, Graves' statement said.

Before the Beerfest actor died, 'several bystanders tried physically restraining Kappy from jumping but failed to hold him,' TMZ reported.

No one else was reported injured in the incident, and the investigation has officially been closed.

Kappy's Instagram post on Sunday was captioned, 'Beware the man has nothing to lose, for he has nothing to protect.'

In the message posted as a screenshot of text he wrote, '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 ignorance that these revelations had not come sooner.

'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.'

Kappy penned a scathing assessment of his own character, writing, I have used people for money. I have betrayed MANY people and much trust. I have sold drugs. I have tax delinquencies. I have debts. I have abused my body with cigarettes, drugs and alcohol.'

Throughout the message, Kappy mentioned 'the Q movement' and said 'I am so so sorry to have brought shame upon the greatest military operation of all time.

Kappy referenced suicide in a metaphor, as well, writing, 'Q says they give people enough rope to hang themselves, and I have hung myself.'

He also claimed to have 'betrayed' Donald Trump and Jesus Christ in the missive, referencing death again.

'I have told people in the Trump administration that I am willing to admit to my many crimes in a public setting, and committed to execution, in a public setting,' Kappy wrote. 'A nation cannot suffer its traitors, and I am no exception.'

Taking to the social media site on Monday, Kappy wrote a scathing assessment of his own character, which included the words, 'I HAVE NOT been a good guy'

Kappy was reportedly being investigated by the Los Angeles Police Department for threatening Paris Jackson , and other celebrities.

According to TMZ, Kappy allegedly choked Paris during a game night party.

This might have been referenced in his farewell message, as well, where he wrote, 'I have been abusive to people WHO LOVED ME, including my FAMILY.

'To the many people I have acted abusively towards, I am very, very sorry. To my former friends I have used and betrayed, I am sorry.'

The 21-year-old model had allegedly received 'rambling and scary' texts from her former pal. Sources claim she initially responded to them to help him because she though he was suicidal at that time, as well.

She was later forced to move home and hire extra bodyguards, along with blocking Kappy's number.

Police opened an investigation into the actor after seeing a particularly menacing tweet from Kappy on August 1 that read: 'In light of the interesting traffic happening around my house I want to make something CRYSTAL CLEAR: While I am a VERY strong advocate of peaceful disclosure, make no mistake, assets are in place and if you kill me or even try, it will rain .50 cals in the Hollywood Hills.'

Per his Twitter account, Kappy appeared to be on a crusade to take down people he believes are sexually abusing children.

He wrote in his post on Sunday, 'While it's true I have spent many, many hours of research and disseminating information about bad actors, I have had SO LITTLE CARE for introspection about MY OWN actions.

'And while it's true I have outed many pedophiles that were former FRIENDS, I remained in their sphere for much longer than I should have, and attempted to gain from them AFTER I knew about their actions. And in my SHEER ARROGANCE I did not even reflect on this fact.'

His timeline is full of retweeted news stories about pedophiles and rants about high-profile people accused of sex crimes and some who aren't. He accused Green of being a pedophile in a video posted in July.

Kappy had also, according to his Twitter, tried to reach out to Corey Feldman to take on pedophilia together. Corey blocked him on Twitter and did not respond.

He previously called out the cast of Guardians of the Galaxy for defending ousted director James Gunn and Bill Clinton.

Kappy added, 'It should be noted that I have recently been made to believe that I am the reincarnation of Judas Iscariot, the great betrayer. And while I could have utilized this period of great awakening to AWAKEN myself, I have used it focused on the darkness OF OTHERS and not the darkness WITHIN.'

Kappy ended his final message writing, 'See the light in others. Nurture the light in yourself. This lesson has come too late for me, but perhaps it can inspire you. 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.'

The letter was mysteriously dated at the bottom, 'July 4th, 2019' and signed off with 'Return of the King Return to THE LIGHT.'
