A charity toy drive at Desert West Park in Phoenix on the afternoon of November 26, 2017, ended in tragedy when 27-year-old Andrew Alvarado was shot multiple times in a large crowd at about 4:30 p.m. Bystanders performed CPR until emergency responders arrived, but Alvarado succumbed to his wounds at a nearby hospital.

Witnesses described a chaotic scene and told police the shooter was a Hispanic male who fled immediately. Several witnesses later identified the gunman and said he was known to Alvarado rather than a random assailant. Police arrested 26-year-old Miguel Flores at his home just before midnight the same day and booked him on charges of first-degree murder. The motive has not been released.

If anyone who attended the event or knew Andrew has information that could clarify what led to the shooting, please share tips with Phoenix police.
