Wichita ? A Kansas prosecutor says officers were justified in using deadly force against a man who shot and killed a sheriff’s deputy near Wichita.

Sedgwick County Deputy Brian Etheridge was killed Sept. 28 in an ambush at a home southeast of Wichita.

Officers found the suspect, 27-year-old Richard Lyons, several hours later hiding in a field. Authorities said Lyons opened fire with the slain deputy’s pistol. Officers returned fire, hitting Lyons seven times. He died later at a hospital.

A report issued Wednesday by Sedgwick County District Attorney Nola Foulston says the officers made reasonable use of deadly force.

The slain deputy had been lured to the house by a bogus 911 call placed by Lyons.
