Rob and Michele Reiner were reportedly warned by medical staff not to let their son, Nick Reiner, live at their Brentwood home after a medication change, weeks before the couple were stabbed to death in December 2025.
CNN reported the acclaimed filmmaker, 78, and his wife, 70, were found dead on 14 December 2025, with their cause of death ruled 'multiple sharp force injuries', and the killings came hours after the couple attended a Christmas party with friends. A source told that in the weeks before the deaths, Nick Reiner, 32, fired his psychiatrist and changed medication because it 'weren't working anymore'.
'The late filmmaker, 78, and his wife, 70, were told it might not be a good idea to allow Nick to "stay at their home" immediately after the med switch, as he could "exhibit even more erratic behavior" as his body adjusted to the change,' the source explained toUs Weeklyon 4 March.
A second insider echoed the same message. Medical staff 'warned Rob and Michele not to let Nick live at home until he got his medication straightened out'.
Despite the warnings, Nick Reiner was living in a guesthouse on the family's Brentwood property at the time of their deaths, a source previously told CNN.
Nick Reiner was also diagnosed in 2020 with schizoaffective disorder, a condition that can combine hallucinations, delusions and severe mood swings. A few weeks before the alleged murders, he is said to have asked his doctor for help with weight gain, a common side‑effect of some psychiatric drugs. According to the reports, his physician responded by changing his pills.
Friends quoted byPeoplemagazine have stressed that, up until the end, Rob and Michele Reiner were still attempting to keep their son within reach rather than push him away.
'They tried everything — giving him space, keeping him close — but his struggles are so deep. It's just a parent's worst nightmare,' one source said last year. 'They were such lovely people, and tried in every way to help their son.'
The couple reportedly took Nick with them to Conan O'Brien's Christmas party the night before they were killed. TheWhen Harry Met Sallyfilmmaker and his wife are said to have brought him along partly so they could keep an eye on him.
According to accounts relayed to the press, the evening did not stay calm. The three allegedly became embroiled in an intense argument during the party and left abruptly.
