The filmmaker's 32-year-old son is charged with two counts of murder in connection with the deaths of Rob Reiner and Michele Singer Reiner.

Nick Reiner was seen in newly released footage that showed the 32-year-old at a Los Angeles gas station shortly before his arrest for the murder of his parents Rob Reiner and Michele Singer Reiner.

Rob Reiner’s twisted son Nick Reiner looked grim-faced and wore a blue suicide prevention vest as he appeared in Los Angeles court for the first time Wednesday for allegedly killing his parents.

"From my interactions with Nick, he seemed like a gentle guy," Douglas Shaffer, who worked on Being Charlie as an executive producer, tells PEOPLE. Nick wrote the movie's script with friend Matt Elisofon, based in part on Nick's experiences with drug addiction from an early age, while dad Rob directed the film.

"All in the Family" star Rob Reiner and wife Michele found stabbed to death in Brentwood home. Rob's son Nick Reiner was later arrested and charged with murder.

Kelly discussed the case against the 32-year-old son of filmmaker Rob Reiner and his wife, Michele Singer Reiner.

Alan Jackson, the attorney who represented Karen Read, Harvey Weinstein and Kevin Spacey in high-profile cases, is defending Nick Reiner.
