A 25-year-old Bronx man has been arrested in connection with her death, according to the New York Police Department. He has two dozen prior arrests, including criminal mischief, assault as well as marijuana possession and sale.
Police say when she got out to investigate, the man jumped into the ambulance, put it in reverse, and struck her before crashing into parked cars.
He added: "We know our EMTs (emergency medical technicians) are fearless. And yet, that danger always exists for them", de Blasio said.
Yadiro Arroyo, 44, and her female partner were travelling in their ambulance in the Bronx when a passing motorist alerted them to a man riding at the back of their vehicle, city officials said.
Arroyo died after she was taken to the Jacobi Hospital and her partner Williams was treated for some minor injuries.
Authorities said the man who stole the ambulance crashed it into a parked vehicle and got stuck in a snow bank before he was taken into custody. Arroyo slipped beneath the ambulance wheels and was killed.
Another EMT, Anastasia Rabos, says Arroyo was a great friend and colleague and was a very humble person.
Video from the chaotic scene shows the driver motionless on the ground as her partner leans over her, crying and yelling, "My partner!
But they should not ever have to be subjected to violence", Mayor Bill de Blasio said Thursday night. Arroyo and her partner pulled the vehicle over and both got out to help, according to a press release from the New York City Police Department. "A lot of heroism was on display today amidst a real tragedy", the mayor said Thursday night.
She was the mother of several children and was dating and FDNY paramedic. He lives down the street from Arroyo, at a building run by Volunteers of America that houses homeless people or those who are cosidered "at risk". There was no immediate information on an attorney who could comment on his behalf. He is expected to be in court on Friday.
