The bystander's video starts with a chaotic scene: An ambulance runs through an intersection in NY, one of its doors open, lights flashing.
Police said the EMT, Yadira Arroyo, 44, who was behind the wheel, got out of the ambulance along with her partner. Anis Nagi, a witness present during the incident said that he and some others stopped the ambulance when they noticed the man riding at the back.
Arroyo's partner was injured as she struggled with the man inside the ambulance before the man allegedly reversed the vehicle, running over Arroyo and killing her, according to police. Her sister-in-law Monica Salazar told the New York Post that Arroyo's children were able to say goodbye. In the video posted to Twitter, she can be heard screaming in anguish as she stands over Arroyo, who is lying motionless in the street.
"We know our EMTs are courageous".
Jose Gonzalez, 25, is charged with three counts of murder, grand larceny and operating a motor vehicle while impaired by drugs, authorities said.
When Arroyo got out of the ambulance, Gonzales got into the driver's seat of the rig.
"She started her day, her shift today, like every other day, and then a senseless act of violence takes her life", Mayor Bill de Blasio said at the press conference.
Gonzalez was described as an emotionally disturbed person, with a criminal history, the NYPD told ABC7. "This person has no business being in this ambulance".
"A lot of heroism was on display amidst a great tragedy", he said. He then turned to see the ambulance backing up into parked vehicles, pushing the vehicles onto the sidewalk.
"I realised he was hijacking the auto".
An MTA Police Officer passing by apprehended the suspect nearby after he crashed the ambulance.
"When he had his hands away from his body, that's when I realized it was a good time for us to take him", Ralph said.
