Juan Antonio Diaz was 18 when he was shot and killed near a strip mall in the 6500 block of Bethany Home Road in Glendale, Arizona, on the evening of October 8, 2016. Police who were nearby on an unrelated matter heard the gunfire and found Diaz inside his vehicle with a single gunshot wound; he was taken to a hospital and pronounced dead.

Authorities arrested 19-year-old Javonte Dujuan Baker-Young at the scene after he tried to flee on foot. Police say a firearm was recovered and that Baker-Young admitted to firing at Diaz’s vehicle and then at two nearby security guards, who were not injured. He was charged with first-degree murder and three counts of aggravated assault with a deadly weapon.
