Prosecutors will charge Nick Reiner with first-degree murder in the deaths of his parents, director Rob Reiner and producer Michele Singer Reiner.

The son of Rob and Michele Reiner has been accused of their murders and is currently being held in police custody without bail.

Los Angeles Police Chief Jim McDonnell said police had taken Nick Reiner into custody. In a later update, police said he was being held without bail. A source close to the family told NBC News that the victims appeared to have suffered stab wounds.
