OPEN RECORDS SUMMARY :

On 01/08/2025, Glendale police responded to a domestic violence call near 47th Avenue and Glendale Avenue, Arizona. Officers later located a man in Horizon Park whom they believed to be connected to the call. The man, Dillon Siebeck, was unarmed and not the man police were seeking. An officer fired multiple shots at Siebeck, killing him. Police did not charge the officer involved, and the Maricopa County Attorney’s Office declined to pursue criminal charges. Siebeck’s family filed a wrongful death lawsuit on 12/31/2025 in U.S. District Court against the City of Glendale and two officers, alleging excessive force, wrongful death, failure to render medical aid, failure to intervene, and related constitutional violations. The lawsuit claims Siebeck was unarmed, did not match the description of the wanted man, and was shot without warning. The case is ongoing and pending in federal court.
