John Herman Tonga, 34, was shot to death on the morning of June 5, 2019, outside a home in Kearns, a Salt Lake City suburb. Police were called about 7:30 a.m. to a residence near 4800 South and 4720 West, where Tonga was found collapsed on the front lawn and another wounded man was leaving the scene. The medical examiner determined Tonga died from a gunshot wound to the chest and had additional gunshot injuries.

Investigators say a group arrived at the house intending to rob a man known to them as Julio. While two members confronted Julio at gunpoint inside, others — including Tonga — entered the room with firearms and shots were exchanged. Witnesses described people fleeing through the front door after gunfire; one of the wounded from the incident later arrived at a nearby clinic and was taken to hospital.

Detectives identified multiple suspects and made arrests in the days and months after the shooting. Lewellyn Auvaa and Joleen Warner were taken into custody shortly after the killing; officers reported finding a pistol and suspected methamphetamine at a motel where Warner was located. Paul Tuese Ama was booked after hospital release; prosecutors charged Auvaa, Ama, and Warner with first-degree murder and related felonies. Months later, a fourth arrest was announced, naming Zachary Rock Ama as providing new details about the robbery-turned-shooting.
