Officials on Thursday identified the three victims as 14-year-old Promise Garcia, 13-year-old Ariella Santos and 38-year-old Melissa Bishop.
Lewis says four other people inside the car were hurt, including the 14-year-old driver. Police say only two occupants of the stolen vehicle were adults, the rest were under the age of 18.
Lewis says shortly after police learned the SUV had been stolen on Nov. 6, authorities received a call of a crash on a frontage road near Interstate 17 and Greenway Road.
The stolen SUV collided with another vehicle that was turning from Greenway Road onto the frontage road on a green light.
The other vehicle's driver was treated at the crash scene.
Lewis said Phoenix police are recommending three counts of first-degree murder, two counts of aggravated assault, two counts of endangerment, one count of felony flight, and one count of theft of means of transportation for the 14-year-old.
The teen was released from the hospital Monday and referred to the Juvenile Correctional Center.
