A man charged with killing six people, including a sheriff's deputy, in a Washington state shooting rampage last year has pleaded guilty.

The Skagit Valley Herald reports that Isaac Zamora entered the pleas to 18 charges including murder, attempted murder and burglary on Tuesday after prosecutor Rich Weyrich announced he would not seek the death penalty.

Zamora pleaded not guilty by reason of insanity to two counts — for the deaths of Deputy Anne Jackson and Alger resident Chester Rose.

Lawyers on both sides are asking that Zamora be committed to Western State Hospital until he is deemed mentally fit to be transferred to state prison to serve a life sentence.

Judge Mike Rickert is scheduled to issue the sentence on Nov. 30.
