At least eight people from the West of the United States tragically died on Sunday after separate incidents of aircraft crashes occurred in New Mexico and Las Vegas.

New Mexico Helicopter Crash Kills 4

In New Mexico, at least four people died when a helicopter suddenly crashed while responding to an area of wildfire, according to The Hill.

"The helicopter and its crew were assisting with a wildfire in the area, providing bucket drops and other air logistics needs to fire crews on the ground," the Bernalillo County Sheriff's Office (BCSO) said in a statement to the New York Times.

The BCSO also said that at least three of its officers died in the helicopter crash, as well as a member of the Bernalillo County Fire Department (BCFD).

The BCSO pointed out that there were no known survivors on board following the crash.

The four deceased responders who died in the New Mexico helicopter crash were identified as Undersheriff Larry Korn, Lt. Fred Beers, Deputy Michael Levison, and BCFR rescue specialist Matthew King.

The BCSO underscored that the tragedy occurred when the responders headed back to Albuquerque after assisting fire crews with the East Mesa Fire.

BCFD spokesperson Robert Arguelles noted that multiple agencies will collaborate to investigate the crash in the southwestern region in the U.S. National Transport Safety Board (NTSB) and the Federal Aviation (FAA) will participate in the probe.

Planes' Collision Kills 4 in Las Vegas

Another incident that involved aircraft on Sunday also claimed the lives of at least four people in Las Vegas after two planes collided at an airport.

According to New York Post, two small planes, single-engine aircraft, collided at Nevada airport, prompting the tragic demise of the victims. The planes reportedly carried at least two people each.

According to FAA, a PIPER PA-46 collided with a Cessna 172 while it was preparing to land. The Piper reportedly crashed into the field east of the airport's runway while the Cessna fell into a water retention pond.

Details regarding the identities of the victims nor what happened to the pilots of the aircraft were unclear. However, the Clark County Department of Aviation said in a statement that there were no survivors in the aftermath of the planes' collision.

Both NTS and FAA are also participating in the probe in connection to the Las Vegas aircraft incident.

Other Fatal Aircraft Incidents in the West

Last month, five people were presumed dead after a military helicopter crashed in a California desert.

Reports claimed that the military plane, known as MV-22B Osprey, belonged to a 3rd Marine Aircraft wing based in Camp Pendleton.

Authorities did not immediately release the identity of the victims, but former Los Angeles Dodgers player Steve Sax confirmed that his son, Capt. John J. Sox, was among the officers killed in the incident.

Sax was reportedly one of the two pilots killed in the crash, along with Capt. Nicholas Loaspio from New Hampshire.
