Photos show charred wreckage from deadly crash of news helicopter in LA

Investigators have released new photos that show the stark aftermath of a news helicopter crash that killed three people in Los Angeles on Tuesday night.

A scorched aircraft and charred storage container were being examined at the scene of the incident on Wednesday. The collision claimed the lives of NBC photojournalist Eliana Moreno and pilot George Marciniw.

The third victim, a pedestrian, was identified as Edy Gutierrez Mejia, 29, by the coroner's office.

The National Transportation Safety Board (NTSB), which is leading the investigation into the incident, said a report on the cause could take up to 18 months.

NBC Los Angeles said its NewsChopper4, which also operated for the Spanish-language Telemundo 52, was in the city's suburb on Tuesday night reporting on a deadly bus crash that had killed two people.

Several other news helicopters were also overhead in the area.

The driver in the bus crash has since been arrested on suspicion of murder.

The cause of the aircraft crash has not yet been determined, officials said. Marciniw was reportedly an experienced pilot.

Mejia, the pedestrian killed when the helicopter came down, was a Guatemalan national who had only arrived in Los Angeles this week, according to NBC News.

Investigators were collecting data at the crash site on Wednesday. The helicopter will be moved to a secure facility, where the NTSB will continue to examine the wreckage.

The NTSB is an independent US government agency that investigates civil transportation accidents.

During a news conference on Wednesday, the NTSB's investigator-in-charge Fabian Salazar said a preliminary report on the incident would be issued within 30 days.

A final report on the cause of the crash could take up to 18 months to be released, he added.

Asked by reporters about video circulating on social media that appears to show the helicopter's viewpoint in the seconds before the crash, Salazar said it is so far "probably the most important evidence" for investigators.

In addition to the three people killed, two others were taken to the hospital.

During emotional live coverage on NBC4 on Tuesday night, veteran news anchor Colleen Williams confirmed it was the local news station's helicopter that crashed.

While news coverage via helicopter is not necessarily unique to Los Angeles, it is more prominent compared to other major metropolitan areas.

LA local news stations regularly break into live programming to broadcast high-speed police pursuits from the air, fly over wildfires and show accidents, protests, and holiday traffic jams in often unscripted, real-time aerials.
