SAGINAW, MI — A Saginaw teen has been charged in the fatal shooting of 17-year-old Deon L. Wiley III, who was killed after a post-prom parking lot party in May near South Washington Avenue and Webber Street. The suspect, now 18 but 17 at the time of the shooting, surrendered at the Saginaw County Courthouse.

Wiley was shot around 12:15 a.m. on May 22 in the parking lot of the Quick Stop after prom festivities, and he later died at a hospital. Another male was also wounded in the same gunfire and was later reported in stable condition.

According to court records and reporting by MLive, prosecutors have now filed the case against the teen suspect months after the shooting, which police said happened during what investigators described as a parking lot party.

The killing drew heavy attention in Saginaw because Wiley was a Saginaw United High School student who had just attended prom and was days away from graduation when he was shot. Police had said at the time that officers were nearby on a traffic stop when they heard gunfire and responded to the scene.

The case marks a major development in a homicide that had remained unsolved since late May.

Presumption of Innocence: A presumption of innocence means that any defendant in a criminal trial is presumed to be innocent until they have been proven guilty beyond a reasonable doubt in a court of law. The defendant in this case is only accused of the charges set forth in the criminal complaint. They are innocent until proven guilty.
