Janell Mora, a 40-year-old mother of two and an associate director at Arizona State University, was shot and killed on the evening of September 26, 2020, while jogging near Power Road and the Loop 202 in Mesa. She had separated from her husband earlier that month and kept her location secret after citing his cocaine use, visits to escort services, and possession of a .38 revolver. Janell had filed for divorce and planned to meet him later that month to discuss ending the marriage.

Witnesses saw her husband, Stephen Mora, chase her from his silver Mercedes; Janell ran to a passing car pleading for help and saying he had a gun. Observers reported seeing Stephen shoot her, then saw a man crouching over her and the Mercedes strike her as she lay in the road. Bystanders performed CPR but she was pronounced dead; an autopsy found a gunshot wound and internal injuries consistent with being struck by a vehicle.

Stephen fled, called his father and then 911 saying he had shot his wife and intended to kill himself. He drove to the Mesa Police Department, shot himself in the face outside the station, and survived. He was arrested in late October 2020 and charged with second-degree murder. Anyone who knew Janell or witnessed the events that evening is asked to share information that could help complete the record.
