Emir Rivas Casillas was 14 when he was shot while riding as a passenger in a car in central Phoenix and died after being taken to a hospital on May 17, 2022. Police learned the vehicle had been traveling near 11th Street by the Moreland/Roosevelt corridor when a 15-year-old who was in the car obtained a firearm and reportedly was handling or playing with it. The gun discharged, a single shot struck Emir inside the vehicle, and companions drove him to a nearby hospital where he was pronounced dead.

Investigators recovered evidence at the scene and treated the shooting as not the result of a deliberate attack but as reckless handling of a weapon. Detectives identified and arrested the 15-year-old as the person who fired the gun; authorities did not release his name because of his age and did not specify the exact charge publicly. It is recorded as an accidental shooting treated as a homicide because a life was taken through unlawful use of a firearm. Did anyone in the area see the car or know the teens involved that afternoon?
