Tremonton shooter used high-powered rifle to kill officers, police say

TREMONTON, Utah (ABC4) — The alleged shooter in an incident that left two officers dead and another injured in Tremonton on Sunday used a high-powered rifle in the killings, court documents state.

The suspect, identified as Ryan Bate, 32, has been arrested on two counts of aggravated murder (capital murder), attempted aggravated murder (first-degree felony), and assault (class-B misdemeanor).

Just before 9:20 p.m. on Aug. 17, Tremonton police officers responded to a domestic violence call on the 700 North block of 200 East in Tremonton. Upon arrival, Bate, who was armed with a high-powered rifle, opened fire on two officers.

Both officers died as a result of their injuries.

A Box Elder County deputy responded to a call for backup and was shot while inside his vehicle, sustaining serious but non-life-threatening injuries. His police service K-9, who was located in the rear compartment of the vehicle, was also shot and sustained serious but non-life-threatening injuries.

While details are limited, Bate was later apprehended by police. At his home, investigators recovered a high-powered rifle and spent shell casings.

Bate has a history of domestic violence, according to court documents, and was arrested on May 8, 2024, due to a domestic violence incident.
