ALTURAS, Calif. (AP) – The defendant in the slaying of a Modoc County sheriff’s deputy has pleaded not guilty to a murder charge. Jack Lee Breiner entered the plea in Modoc County on Friday amid heavy security that included officers on the roof of the courthouse. Modoc County sheriff’s officials say Breiner shot and killed deputy Jack Hopkins on Oct. 19 south of Alturas. The 31-year-old Hopkins was responding to a domestic disturbance call. Hopkins was the fourth California law enforcement officer to die in the line of duty in a two-week span. Breiner was arrested after a chase and shootout with the sheriff that left both wounded. Breiner also entered a not guilty plea to an attempted murder charge in the shootout.
