Investigators have not released a detailed timeline of the killings but confirmed that the victims died of multiple stab wounds. Detectives recovered what they believe to be the murder weapon inside the residence, though forensic analysis is ongoing. No additional suspects have been identified.
Arrest and Charges
Police located Nick Reiner near the USC campus approximately eight hours after the bodies were found. Officials credited “good, solid police work” for the swift apprehension, citing license-plate readers, neighborhood surveillance and mobile phone data as useful tools. Reiner was transported to the Metropolitan Detention Center and held without bail. On Tuesday, prosecutors filed two counts of first-degree murder with special circumstances, a designation that can increase potential penalties if convicted.
At a press briefing inside the Hall of Justice, District Attorney Hochman said his office would “pursue the case to the fullest extent permitted by law.” Arraignment is scheduled for December 23 in Los Angeles Superior Court. If convicted, Reiner could face life imprisonment without the possibility of parole.
Background on the Suspect
Nick Reiner has spoken publicly about long-term struggles with substance abuse that began in adolescence. In 2016, he collaborated with his father on the film Being Charlie, a semi-autobiographical project depicting the challenges of drug addiction and rehabilitation. In promotional interviews at the time, both father and son discussed multiple treatment attempts and periods of relapse.
According to sources familiar with the investigation, family members and guests observed a heated argument between Nick Reiner and his father at a holiday gathering on Saturday night, December 13. Witnesses reported that the younger Reiner appeared agitated, though no physical confrontation was noted during the event. Authorities are examining whether the dispute played a role in the subsequent violence.

Community and Industry Response
News of the killings has reverberated across Hollywood, where Rob Reiner earned directing credits for films such as When Harry Met Sally… and A Few Good Men. Michele Singer, a producer and philanthropist, was active in several Los Angeles charitable organizations. Police have increased patrols around the couple’s Brentwood neighborhood, and a private security firm has been hired to monitor the property pending probate proceedings.
Legal experts note that California’s special-circumstance allegations can carry significant consequences. Under state law, a murder committed against multiple victims qualifies for enhanced sentencing. More information on California homicide statutes is available on the California Office of the Attorney General website.
Next Steps in the Case
Investigators are continuing to collect digital evidence, interview additional witnesses and review financial records. A search warrant executed at Nick Reiner’s living quarters reportedly yielded personal journals and electronic devices now being analyzed by forensic specialists. Authorities have not disclosed any motive but confirmed that toxicology tests are being conducted.
Funeral arrangements for Rob Reiner and Michele Singer have not yet been announced. Friends of the family have established a temporary memorial outside the Brentwood home, leaving flowers and notes along the sidewalk.
The Los Angeles Police Department has asked anyone with direct knowledge of Nick Reiner’s movements between Saturday night and Sunday afternoon to contact its West Bureau Homicide unit. Tipsters may remain anonymous through the department’s Crime Stoppers program.
