The man accused of killing Clark County sheriff's Sgt. Jeremy Brown pleaded not guilty Thursday to new charges in connection with the July 23 shooting.
Guillermo Raya Leon, 27, of Salem, Ore., was arraigned in Clark County Superior Court on amended information of possession of a stolen firearm, first-degree trafficking in stolen property, first-degree burglary and theft of a motor vehicle. He was already charged with first-degree aggravated murder and another count of possession of a stolen firearm.
His trial is scheduled for Oct. 31.
Investigators have said that Raya Leon admitted to shooting Brown, 46, while the detective was seated in an unmarked police SUV at an east Vancouver apartment complex.
Detectives were following Raya Leon, his brother, Abran Raya Leon, 29, and his brother's wife, Misty Raya, 36, that day as part of an investigation into the theft of dozens of firearms and 20,000 to 30,000 rounds of ammunition from a Hazel Dell storage unit in early June.
Investigators and the prosecution say they believe the weapon used to shoot Brown was one of the stolen guns.
Court records state that Misty Raya's friend, Lani Kraabell, was helping them find buyers for the stolen guns when Guillermo Raya Leon shot Brown.
Kraabell pleaded guilty June 10 to second-degree manslaughter in connection with Brown's death and pursuant to an agreement that she cooperate with the criminal cases against her co-defendants. She was sentenced to six years in prison.
