Nick Reiner has been very candid about his addiction and mental health struggles. On Monday, the 32-year-old was arrested and charged after allegedly murdering his parents Rob and Michele Reiner in their Brentwood home on Sunday afternoon, allegedly slitting their throats. Not even 24 hours after the father and son got into a "very loud argument" at Conan O'Brien's holiday party the night before. According to TMZ intel, Michele had expressed to friends in recent months that they were running out of ideas to help their son defeat his demons.
