Prosecutors will pursue the death penalty against the man accused of shooting and killing two Tremonton-Garland police officers and wounding a third sheriff’s deputy and his service dog, according to court documents filed Wednesday that shed new light on the shooting.

Two Utah police officers were killed and a third was injured along with his service dog when they were fired upon by a suspect inside a home while responding to a domestic disturbance Sunday night. The shooting unfolded in Tremonton, about 70 miles north of Salt Lake City, Brigham City Police Chief Chad Reyes said at a news conference Monday.
