The Los Angeles County Medical Examiner has ruled that veteran news helicopter pilot George Marciniw, 70, died from blunt force trauma in last Tuesday’s fatal crash near a Chatsworth warehouse.
Marciniw was at the controls of the aircraft when it plummeted from the sky while providing aerial coverage for NBC Los Angeles and Telemundo 52. The single-engine helicopter went down in the afternoon hours, killing all three people on board and sparking a fire that drew emergency crews to the industrial area.
His passenger, NBC reporter Eliana Moreno, also suffered blunt force trauma, but her cause of death included additional devastating injuries. The coroner found she sustained “thermal injuries and inhalation of products of combustion,” indicating she was alive and exposed to fire and smoke after the initial impact.
The crash occurred during a news run that had begun as coverage of a deadly bus collision elsewhere in Los Angeles. That earlier incident, a Metro bus crash in the downtown area, left two people dead and had drawn multiple news helicopters to the scene. The helicopter carrying Marciniw and Moreno had departed that coverage when it went down approximately 30 miles northwest in the San Fernando Valley.
A third victim, whose identity was confirmed separately in subsequent reports, also perished in the wreckage. The aircraft came to rest near a warehouse complex, where witnesses described seeing it fall without warning before bursting into flames on impact.
The National Transportation Safety Board and Federal Aviation Administration have launched investigations into the mechanical and operational factors that led to the sudden loss of the helicopter. Investigators are examining maintenance records, pilot communications, and weather conditions from the flight path.
The dual tragedy of the bus collision and helicopter crash made last Tuesday one of the deadliest days for Los Angeles news coverage in recent memory. The bus incident itself involved a driver who authorities later arrested, with allegations emerging that she was under the influence of drugs at the time of the collision.
Marciniw’s death marks a significant loss to the aviation community, where he had built decades of experience flying news and commercial helicopters across Southern California. Colleagues in the industry remembered him as a steady presence in the skies above the region’s breaking news scenes.
Moreno’s additional injuries from fire and smoke have drawn particular attention from safety experts, who note that post-crash survivability remains a critical concern in helicopter design and emergency response. The combustion products she inhaled would have included toxic gases released as the aircraft’s materials burned.
The coroner has not released additional findings regarding whether any of the victims could have survived the initial impact, or how quickly fire engulfed the wreckage. Final autopsy reports typically take weeks to complete as toxicology and other tests are processed.
The crash has prompted renewed discussion among broadcast news operations about helicopter safety protocols, though industry veterans note that the aircraft remain essential for covering sprawling metropolitan areas like Los Angeles during breaking events.
The NTSB’s preliminary report is expected within two weeks, with a full probable-cause determination likely to take more than a year.
