Kolby Treshaun Peterson was 21 when he was shot and killed the evening of January 22, 2020, at Mountain View Park and Community Center near 11th Street and Grovers Avenue in north Phoenix. Officers found Peterson with a gunshot wound around 10:15 p.m.; Phoenix Fire medics took him to a hospital where he was pronounced dead on arrival.

Investigators say the killing occurred during an attempted armed robbery. Court documents allege Peterson, a 19-year-old companion, and 19-year-old Laverdous Moore Jr. had planned to steal marijuana from another person at the park. The intended victim fought back and fatally shot Peterson, then fled. Moore was arrested on February 12 near 7th Street and Bell Road and was booked on one count of first-degree murder after admitting his role in the planned robbery. Arizona law allows a murder charge if an accomplice is killed during a felony.
