Nick Reiner was struggling with his mental health after being diagnosed with schizophrenia. On Sunday, Nick's parents Rob and Michele were found dead in their home, horrible crimes for which he has been arrested. Now, an insider for TMZ is revealing he was diagnosed with schizophrenia, and in the weeks leading up to the murders, changes in his medication were causing him to be "erratic and dangerous." Oh, no. Two sources told the outlet on Friday that the 32-year-old was under the care of a psychiatrist for mental illness.
