The directory includes cases with reported arrests or indictments and cases with documented convictions. Mary Collier’s source includes an April 2026 sentencing update; Joshua McCoy’s record links to a June 2023 conviction and sentencing report. Each card dates its status to the reporting reviewed.
Charges are allegations, not convictions. An older arrest report does not establish the current court outcome or that a case remains open.
Each record has a named victim, a supported incident or discovery date, a location reported as San Tan Valley and a documented homicide basis. Counts refer to victims, not separate incidents. Source reports establish the case details; subsequent appeals and dispositions have not been comprehensively checked. Records from the community’s earlier years are not presented as a current-boundary municipal crime count.
No. The seven records represent documented cases reviewed for this directory. They are not an official annual total or a complete historical list. Additional cases require source and location verification.
No map pins have been assigned yet. Each record gives the location described in the source, but precise scene coordinates have not been verified.
Homicide means one person caused another person’s death. Murder is a criminal legal classification. Case cards preserve distinctions such as homicide investigation, murder charge, conviction, unsolved case and murder-suicide rather than treating them as interchangeable.
The case cards link to ABC15, FOX 10 Phoenix, Arizona’s Family and PEOPLE reporting. Sources attribute information to sheriff’s investigations and court proceedings. Reported arrests, charges and convictions are distinguished.
