The incident took place on I-295 Wednesday afternoon as the ambulance was taking a shooting victim to a local medical facility. It then took several minutes for a backup ambulance to arrive on the scene.
The driver told investigators that the indicator lights on the emission control system suddenly went from a warning to shut down in just seconds and, as the engine fizzled out, she was able to pull the vehicle to the side of the road.
When Ambulance 19 broke down on the road, it was taking 34-year-old Nathaniel McRae, who had just been in a shootout with police, to the hospital.
An EMT continued to perform CPR while the crew waited for a second ambulance, but McRae was pronounced dead at Howard University Hospital.
What is not yet know is exactly how long the crew had to wait for the second ambulance to arrive – but a spokesman for the fire department said “the delay did not affect care in any way.”
