TREMONTON, Utah — Two police officers were killed and another injured, along with a K-9, after a suspect opened fire following what was described as a domestic disturbance Sunday night in Tremonton. The unidentified suspect is now in custody while the officer who was not killed and the K-9 are reported to be in fair condition.

Tremonton Police Chief Dustin Cordova says two officers who lost their lives Sunday night also saved others who later responded to the scene.
