Nick Reiner, the youngest son of director Rob Reiner and his wife Michele, has been charged with first-degree murder after the Hollywood couple was found dead in their home.

Los Angeles County District Attorney Nathan Hochman announced the charges on Tuesday afternoon, two days after Reiner was arrested on suspicion of murder. The Reiners were reportedly found dead with stab wounds in their Los Angeles home on Sunday afternoon.

“These charges will be two counts of first-degree murder with a special circumstance of multiple murders. He also faces a special allegation that he personally used a dangerous and deadly weapon, that being a knife,” Los Angeles County District Attorney Nathan Hochman said.

Now that prosecutors have decided to file charges, Reiner is expected to appear in court.

“He is going through medical clearance, something that everybody who gets arrested and gets held in a Los Angeles County Sheriff’s Department jail goes through,” Hochman said. “Once he is medically cleared, he will be brought to court to be arraigned on these charges. At that point, he will enter a plea of guilty or not guilty.”

Reiner was initially scheduled to appear in a Los Angeles courtroom at 8:30 a.m. local time on Tuesday. But he did not receive medical clearance to move from the jail to the courthouse, his attorney Alan Jackson told The New York Times. Jackson described medical clearance as standard procedure but provided no further information.

Reiner has a well-known history of drug addiction, a struggle that began when he was a teenager and saw him enter rehab on several occasions, beginning when he was 15. Reiner has also said that he experienced homelessness a number of times in several states.
