Nick Reiner had history of violence before alleged killing of parents Rob and Michele Reiner, sources say

Friends, neighbors, and acquaintances of Nick Reiner say the 32-year-old had a long-standing reputation for instability and violence well before he was charged with the brutal killing of his parents, actor-director Rob Reiner and his wife, Michele, inside their Los Angeles home.

According to multiple people who knew the family, news of the couple’s deaths was shocking, but the arrest of their son was not entirely unexpected to those familiar with his past struggles. Several neighbors said they “instantly knew” Nick was involved once authorities confirmed a suspect, citing years of erratic behavior, addiction issues, and family conflict.

One longtime neighbor described Nick as “always troubled,” claiming there had been previous violent incidents involving him, though details were not disclosed. The neighbor said Rob Reiner was deeply affected by his son’s inability to overcome substance abuse and had spent years trying to get him help.

Others echoed similar sentiments, saying Nick had been in and out of rehab since his teenage years and resisted long-term inpatient treatment. While his parents reportedly encouraged professional help, he preferred to stay at home, which often led to tension within the family.

Nick himself previously spoke publicly about a drug-fueled episode in 2018, admitting on a podcast that he trashed part of his parents’ home during a prolonged binge. He described punching walls and destroying property after being awake for days on stimulants.

People living in the upscale Brentwood neighborhood where the killings occurred said Nick had been staying at the home for at least a year. A private security guard hired to patrol the area recalled regular encounters with him, noting that “something always felt off,” though he said he never personally witnessed violence.

Despite concerns about Nick’s behavior, those who knew Rob and Michele Reiner described them as exceptionally kind and generous. Neighbors and workers in the area said the couple regularly checked in on others, offered help when needed, and were deeply loved within the community.

Flowers and candles have been placed outside the home as news of the tragedy spread, while media gathered at the scene throughout the day. Friends of the family expressed heartbreak not only over the violent deaths but also for the surviving children, who now face the aftermath of an unthinkable loss.

Nick Reiner has been charged in connection with the killings and remains in custody as the investigation continues. Authorities have not released further details about a possible motive.
