Plea deal rejected in attempted murder-by-insulin case in Port Angeles; July trial set

PORT ANGELES — Robbie Wayne Davis, a Port Angeles man who allegedly tried to kill a relative with insulin injections in 2013 and 2014, has rejected a plea offer.

“We are on for trial in July,” said Michele Devlin, Clallam County chief criminal deputy prosecuting attorney.

Davis, 40, is charged with three counts of first-degree attempted aggravated murder, three counts of first-degree aggravated assault-administers a destructive or noxious substance and two counts of harassment-threats to kill.

Port Angeles police allege that Davis tried to murder his non-diabetic stepuncle, Richard Haynes, by administering lethal doses of insulin in December 2013, March 2014 and June 2014.

The harassment charges are related to intercepted jailhouse letters in which Davis threatened a deputy prosecuting attorney and a caseworker, according to the affidavit for probable cause.

Davis, who is being held in the county jail on $50,000 bail, faces a three-week trial beginning July 18 in Clallam County Superior Court.

An initial plea offer was submitted to the defense in April 2015.

Davis had been considering a second plea offer since Jan. 15.

Superior Court Judge Brian Coughenour on Friday scheduled a June 23 hearing for pretrial motions.

Davis’ trial has been postponed several times since his arrest because of delays with DNA tests and a conflict with a judicial conference.

Davis was booked into jail June 26, 2014.

The third alleged murder attempt was reported by an Olympic Medical Center nurse, who told authorities that Haynes had dangerously low blood sugar after being visited by Davis in the hospital.

Haynes died of an unrelated illness in October 2014 at the age of 57.
