Thor actor Issac Kappy dies at 42

Actor Isaac Kappy, who has appeared in Thor in 2011 and Terminator: Salvation, has died.

US police confirmed that the 42-year-old died in Arizona and that his death is being investigated as a suicide.

Kappy played the pet store clerk in 2011's Thor alongside Chris Hemsworth, and also had roles in Channing Tatum rom-com 10 Years and US comedian Rachel Dratch's show Late Night Snack.

In a lengthy post to Instagram two days ago, he said he had been 'a pretty bad guy throughout my life'.

“I have betrayed MANY people and much trust. I have sold drugs. I have tax delinquencies. I have debts,” he said. “I have abused my body with cigarettes, drugs and alcohol.

“I have been abusive to people WHO LOVED ME, including my family. Earlier this week, I committed an act so flippantly without thought that will become synonymous with short sightedness and petty, vile greed, and in the end, has cost me everything.

“This lesson has come too late for me, but perhaps it can inspire you.”

Kappy hit headlines in an incident last year when he allegedly assaulted Michael Jackson's daughter Paris, choking her at a party.

Jackson, a former friend, hired security and moved out of her home after becoming concerned about Kappy's behaviour.
