Nick Reiner was reportedly disciplined while behind bars after becoming volatile with deputies following a prison shower.
The incident unfolded on April 27 at around 8:15 a.m. inside Los Angeles County Twin Towers Correctional Facility, where Rob and Michelle Reiner's son – who is accused of killing his parents – is housed alone in a specialized medical observation unit under heightened security measures, a news outlet reported on Wednesday, July 29.
Nick Reiner Became 'Extremely Hostile'
Nick Reiner was arrested in connection to the murder of his parents, Rob Reiner and Michelle Reiner, in December 2025.
Sources told the outlet that Nick had just finished showering and changed into new inmate clothing when he became increasingly frustrated that deputies had not immediately returned to escort him to his cell.
"He was recalcitrant, extremely hostile, creating a verbal disturbance, refusing to follow rules and not listening to any commands," the insider explained. "He was yelling, screaming, being disrespectful and shouting many profanities."
Nick Reiner Became 'Upset and Hostile'
Rob Reiner and Michelle Reiner welcomed three children during their nearly 36-year marriage.
The delay was reportedly due to an emergency elsewhere in the facility, where another inmate suffered an apparent overdose, requiring officers to respond before returning to escort Nick.
"[He] became very impatient. He was upset and hostile because no one was coming back right away and he wasn’t attended to," the source explained. "He had finished showering and changed and wanted to return to his cell. When it took too long, he became frustrated and angry."
