Did Rob Reiner receive credible threats after criticizing Trump and who investigated them?

1. The basic facts: authorities treating this as an apparent homicide

Multiple outlets report that two people discovered at a Brentwood address associated with Rob Reiner were later confirmed by city leaders to be Reiner and his wife, and that Los Angeles Police Department robbery‑homicide detectives are conducting a formal homicide inquiry ^{[1] [4] [5]}. LAPD officials said detectives were awaiting search warrants and that the medical examiner will determine cause of death; the department has not announced suspects publicly ^{[1] [6]}.

2. Reiner’s public record of criticizing Trump — well documented

Reporting and profiles collected since his death make clear Reiner was an outspoken Democratic activist and frequent critic of Donald Trump, publicly calling Trump “mentally unfit” and decrying his actions on immigration, free speech and other issues in interviews and op‑eds over many years ^{[7] [8] [2]}. Profiles note he participated in organized criticism of Trump policies — for example signing statements around the Jerusalem decision — and used his platform to denounce what he characterized as threats to democratic norms ^{[2] [9]}.

3. Public fears and statements about danger — Reiner voiced concern himself

On camera and in interviews, Reiner expressed fear about speaking out and warned of personal risks. In one interview he said, “This may be the last time you ever see me,” while discussing free‑speech fights and high‑profile suspensions; outlets flag that he was worried about broader threats to critics of powerful figures ^[3]. Those remarks are reported as context for his activism, not as evidence of a contemporaneous law‑enforced threat investigation.

4. What the sources say (and do not say) about threats after his criticisms

News organizations repeatedly record Reiner’s longstanding critiques of Trump, but the items provided do not report that law enforcement had opened a distinct, credible threats investigation tied to those critiques prior to the homicide inquiry. Sources explicitly say police are investigating the deaths as an apparent homicide and that detectives are involved, but they do not document preexisting credible threat reports to police linked to his statements about Trump ^{[1] [4] [5]}. Available sources do not mention any formal federal or local threat probe launched because of his political commentary.

5. Who is investigating the deaths — and what that investigation covers

Media accounts state the LAPD’s Robbery Homicide Division and homicide detectives are leading the investigation into the scene and deaths; officials said they would conduct searches under warrant and coordinate with the coroner for cause of death ^{[1] [10]}. Local law enforcement briefings, per reporting, emphasized the ongoing nature of the probe and that they were not publicly naming suspects or persons of interest while detectives pursued leads ^{[6] [1]}.

6. Where reporting leaves gaps and why that matters

Press coverage documents Reiner’s political profile and his own expressions of fear, but none of the itemized sources tie a documented, credible external threat or prior police investigation of threats to him directly to the homicide. That gap matters because personal statements of worry and media coverage of political activism are not, by themselves, evidence that a specific credible threat existed or that it was investigated before these deaths ^{[3] [2]}. Available sources do not mention whether the FBI or other agencies are involved; they focus on LAPD homicide detectives ^[1].

7. Competing narratives and what to watch for next

Some commentary and social posts may conflate Reiner’s outspoken anti‑Trump stance with motive or threat narratives, but reputable outlets cited here stick to verifiable procedural facts: LAPD homicide detectives are investigating and officials have not publicly named suspects or linked the killings to his politics ^{[4] [1]}. Readers should watch for forthcoming LAPD statements, coroner findings and whether federal agencies announce any involvement; those updates will be the only reliable basis for linking motive or prior threats to the deaths ^[1].

Limitations: reporting remains fluid and the sources provided do not contain results of forensic or criminal‑investigative findings, nor do they record any prior, documented credible threat investigation tied specifically to Reiner’s criticisms of Donald Trump ^{[1] [3]}.
