Sources previously told The Post that Rob and Michele’s daughter, Romy, found the couple’s bodies with their throats slit and multiple stab wounds on Sunday.

The couple’s son Nick was arrested later that evening in connection with his parents’ deaths and has since been charged with two counts of first-degree murder.

Nick, 32, has been locked away in solitary confinement at Twin Towers Correctional Facility in downtown Los Angeles, and remains on suicide watch following his parents’ murders, a police source told People.

Just hours before their deaths, Rob and Michele attended Conan O’Brien’s holiday party on Saturday night. While there, a lifelong family friend told The Post that Rob and Michele got into a big fight with Nick.

“They had had an argument at Conan’s holiday party, and Rob had been telling people that they’re scared for Nick and scared that his mental state was deteriorating,” the insider shared.

Nick was reportedly diagnosed with schizophrenia prior to the murders of his parents, and the medications he was taking were allegedly making him act “erratic and dangerous,” according to TMZ.

Nick’s arraignment has been set for Jan. 7, 2026. He’s expected to plead not guilty by reason of insanity.
