Residents of this northern Utah town are in mourning after two of the city’s police officers were fatally shot and a Box Elder County sheriff’s deputy and his police K-9 were wounded Sunday night.

Two police officers were fatally shot and a third was wounded when a man opened fire as they responded to a domestic violence call at a home in Tremonton, Utah.

“We’re a tight-knit community,” Mr. Holmgren said. “It was just a regular Sunday until it wasn’t.”
