They also mentioned that the couple believed they had “tried everything,” but nothing was working.

Nick's history of substance abuse dates back over a decade and was talked about by Reiner in an interview with the Los Angeles Times in September 2015.

“We were desperate, and because the people had diplomas on their wall, we listened to them when we should have been listening to our son,” he added.

Reiner, at the time, further claimed that those individuals who were meant to help Nick influenced them not to believe their son.

“They would tell us he’s a liar, that he was trying to manipulate us. And we believed them,” Reiner also remarked.
