EPHRATA, Wash. -

A Grant County judge has quashed a motion filed by convicted murderer David Nickels to have his case involving the 2009 killing of Ephrata resident Sage Munro dismissed.

Judge Evan Sperline, in ruling on Nickels' fifth motion to dismiss, said that while Nickels did prove there was mismanagement in the handling of the investigation into Munro's killing, he did not, however, establish there was prejudice.

"Today the trial court did the right thing and denied the motion for a new trial," Grant County Prosecutor D. Angus Lee wrote in an e-mail to KXLY. " We are very satisfied with this ruling and look forward to sentencing.  I hope this ruling brings greater closure to the families of the victim, Sage Munro."

Sage Munro was shot point blank in the chest in front of his home on Dec. 29, 2009. He was found by police responding to the scene inside his living room, where he had walked to before he collapsed and died.

Six months later in June 2010 Nickels was arrested in Montana for Munro's killing. Court documents reported at the time that Nickels, upset that Munro was dating his ex-girlfriend, traveled from East Helena, MT. to Ephrata, confronted Munro and then shot him.
