Rob Reiner had good intentions when deciding to bring his son Nick Reiner to Conan O'Brien's Christmas party on Saturday, December 13.
The late film director reportedly asked the comedian if he could bring Nick to the A-list holiday bash due to concerns Rob and his wife, Michele Singer Reiner, faced about the 32-year-old's mental health issues.
Hours after the party, Rob and Michele were found slaughtered in their Brentwood, Calif., home, with Nick being arrested for murder in connection with his parents' tragic deaths.

Rob Reiner and his wife, Michele, were found dead on Sunday, December 14.
It's unclear if their son left at the same time as them, however, a separate source told People that Nick had been living with his parents at the time of the murders.
White the exact timeline hasn't been confirmed, an eyewitness at the party told NBC News that Nick "stormed off" during Conan's gathering after getting into a tiff with comedian Bill Hader, leaving guests concerned.
Nick allegedly interrupted Bill's conversation, and when the Saturday Night Live alum told him he was in the middle of a private chat, Rob's son stood still and stared before walking away in a huff.

Romy Reiner discovered her parents' bodies inside of their home.
At some point between leaving Conan's party and his sister Romy discovering her parents deceased bodies at around 3:30 p.m. on Sunday afternoon, Nick was accused of entering Rob and Michele's Brentwood, Calif., mansion and slitting their throats with a knife.
Nick was said to have checked into The Pierside Santa Monica at around 4 a.m. on Sunday using his own credit card. While there were no signs of blood or cuts on his body, staffers claimed he looked "tweaked out" and later found his hotel room "full of blood."
He was taken into police custody by Sunday evening and booked for murder on Monday morning, December 15.
