On the night of August 19, 2017, 17-year-old William Will Anothony Ryan was sitting on the hood of a parked car outside his home in Magna, Utah, when a vehicle approached and multiple gunshots were fired in a drive-by shooting. Ryan was struck in the head and died at the scene; another 17-year-old who was inside the car was wounded and survived. Authorities quickly treated the shooting as gang-related and identified a 17-year-old suspect.

On August 25, 2017, Unified Police arrested a teen with known gang affiliations after locating and seizing a white Volkswagen Jetta believed to have been used in the attack; the suspect was booked on charges that included murder and aggravated assault. The family said William wanted to become a mechanic and had tried to distance himself from gang involvement; his mother described the aftermath as an endless nightmare and the family moved because their home had become a horror scene.

Anyone who knew William, his movements that night, or the events leading up to August 19, 2017, is asked to share what they know.
