Nick Reiner was allegedly subject to disciplinary action for a purported outburst in prison as he awaits trial for the murders of his parents Michele and Rob Reiner. The 32-year-old, who had a history of substance abuse and was also reportedly diagnosed with schizophrenia, is being held in solitary confinement in the specialized medical observation unit at the Twin Towers Correctional Facility in Los Angeles. Inmates in that unit are individually taken to and from the showers by deputies, who as a precaution are able to see their heads and feet. A source has now claimed that on April 27, Nick took a shower, got dressed in a fresh uniform and grew 'very impatient' while waiting to be brought back to his cell by deputies who were delayed because another inmate apparently overdosed. #NickReiner #RobReiner #MicheleSingerReiner #TheCrimeDesk #TrueCrime
