FDNY mourns loss of Yadira Arroyo, mother and EMT veteran, who was run over by her own ambulance

Yadira Arroyo was an FDNY veteran and a 44-year-old mother to five children.

— -- The New York City Fire Department is mourning the loss of an emergency medical technician and mother of five who died Thursday night after she was run over by her own ambulance by a suspect who stole the vehicle.

At this time, a man entered the driver's side of the ambulance. Arroyo and her partner tried to prevent the individual from driving away but the man put the ambulance in reverse, knocking Arroyo to the ground and driving over her with the vehicle. The man continued driving in reverse, striking two occupied cars and a parked, unoccupied vehicle, police said.

The man then drove the ambulance forward, subsequently dragging Arroyo into the middle of the intersection. While trying to turn left, the ambulance crashed into two more parked vehicles before coming to a stop near a corner. The man attempted to flee on foot but was apprehended by an on-duty officer with the Metropolitan Transportation Authority who was on patrol, according to police.

Police officers responding to the incident found Arroyo lying in the roadway unconscious and unresponsive with trauma to her body. She was taken to a local hospital in critical condition, where was pronounced dead, police said.

Arroyo, 44, is the eighth member of the FDNY EMS to die in the line of duty. She was a mother to five children, the fire department said.

Arroyo's EMT partner, a 30-year-old woman, was transported to the hospital for injuries to her neck and shoulder. She is in stable condition, according to police.

No one in the occupied vehicles that were struck during the incident were injured, police said.

During a press conference Thursday night, officials struggled to make sense of the tragedy.

New York City Fire Commissioner Daniel Nigro added, "No matter how many times we do this, it doesn’t make it any easier."

The investigation into the incident is ongoing.
