Authorities continue their investigation as friends, family, and the nation mourns the loss of the brave servicemen. Let’s take a look at all the details of the incident and explore the lives and careers of the fallen Marines.
How did the three US Marines die?
The tragic incident unfolded on the morning of July 23 when deputies from the Pender County Sheriff’s Office discovered the three Marines unresponsive inside a privately owned car parked outside a Speedway gas station in Hampstead, North Carolina.Â
The car’s engine was still running, which led to suspicions of carbon monoxide poisoning. Emergency services rushed to the scene, but it was too late to save their lives.Â
The local sheriff’s office later confirmed that all three deaths of the US Marines were indeed caused by carbon monoxide poisoning. However, they did not immediately reveal whether the deaths were accidental.Â
