The Los Angeles County Medical Examiner announced on Wednesday, December 17, that they died from "multiple sharp force injuries." Rob and Michele were found dead inside of their home on Sunday, December 14.

"Nick's problems have been going on for so long, so while everyone is in a state of shock right now, it's not entirely surprising," an insider shared. "A lot of his anger was directed at his parents for many, many years," the source said. "They did everything a parent could possibly do to help him. Even in his younger years, they really tried to get him help. And then it became a cycle of seeking treatment for him, kicking him out, or him leaving the house, him moving back in. ... This went on for years."
