On the night of May 18, 2017, two young men were found shot to death inside a car in the Garden Grove apartment complex parking lot in Tempe, Arizona. Sixteen-year-old Kayon Williams, a McClintock High School junior described as well-liked and funny, and 20-year-old DeSean Estrada were discovered around 11:15 p.m. with the engine still running; one was in the driver’s seat and the other in the front passenger seat. A third occupant escaped with a graze wound and later aided investigators in identifying suspects.

Investigators determined the victims had gone to the complex to meet people for what they believed would be a drug transaction, which allegedly became an armed robbery that ended in the fatal shootings. Within a week, four men — Brandon Nichols, Taylor Bush, Montre Williams, and Justin Santos, then aged 18 to 20 — were arrested and charged with first-degree murder, aggravated assault, and armed robbery. In March 2018 a fifth suspect, Adrian Carlos Barrios, who was 17 at the time of the killings, was taken into custody on a grand jury warrant after cell phone tower data placed him at the scene and communications tied him to one of the victims.

Anyone who knew Kayon, DeSean, or their movements that night, or who has information about the meeting at the Garden Grove complex, is asked to come forward.
