3 Dead in Construction Accident

Key Largo, FL – Three workers were killed at a construction site in Key Largo Monday morning. Crews responded to the scene near mile marker 106 at 175 Long Key Drive around 8:30 a.m.

Monroe County Sheriff’s deputies say workers became trapped when they went underneath the newly paved road to see why it was settling. Multiple people began to rescue the workers from the manhole.

Two of the workers were pronounced dead while a third worker has not been found and is presumed dead. A volunteer firefighter who was part of the rescue effort was airlifted to Jackson Memorial Hospital in Miami while two deputies were taken to the hospital for observation.

Homes in the area were evacuated as a precaution as HAZMAT teams from Miami-Dade County were called in to help.

Sheriff’s office officials said it’s likely a mixture of methane and hydrogen sulfite gas that killed the men.
