Seventeen-year-old Joseph Seibold, a White/Caucasian male, was shot while sitting in the driver’s seat of his vehicle near 3rd Drive and Chestnut in Mesa, Arizona, on the night of February 17, 2021, at about 10:39 p.m. Joseph was found by Mesa police with a gunshot wound and taken to a local hospital; he died of his injuries the following day. The last communication his father received from him was a text sent minutes before the shooting.

Investigators say a group of teenagers approached the vehicle and one of them fired. Three suspects were seen fleeing; police identified and arrested one, a 14-year-old boy who was charged and sentenced to juvenile prison until his 18th birthday. Two other suspects remain at large. Police released a composite sketch of one outstanding suspect described as a Hispanic male in his late teens with brown eyes and are asking the public for tips.

If anyone has information about the two remaining suspects or the events that night, please contact Mesa Police or Silent Witness.
