32-year-old Nick Reiner has been arrested and booked following the killings of his parents Rob Reiner and Michele Singer Reiner.

WASHINGTON - President Donald Trump on Monday blamed renowned Hollywood director Rob Reiner's outspoken opposition to the president for Reiner's death, delivering the unsubstantiated claim in a social media post.

Reiner, 78, and his wife, Michele Singer Reiner, 68, were found stabbed to death on Sunday, Dec. 14 in their mansion in the Los Angeles neighborhood of Brentwood.

The person who called 911 was reportedly the couple's daughter, Romy Reiner, 29.

The couple’s son, Nick Reiner, 32, was in police custody early Monday in connection with the incident and is being held on $4 million bail. Jail records show he was booked for a felony.

Trump posted a statement on Truth Social blaming the tragedy on the director's political opposition to him. Reiner was a vocal critic of the president and an active Democrat in the film industry.

In his social media post, Trump claimed that Reiner and his wife were killed "reportedly due to the anger he caused others through his massive, unyielding, and incurable affliction with a mind crippling disease known as TRUMP DERANGEMENT SYNDROME."
