Former Pasco Police Officer Arrested For Murder

SPOKANE, Wash. (AP) — Spokane police say they are continuing to investigate a former Pasco police officer who has been arrested in the slaying of a woman in 1986.

51-year-old Richard Aguirre was arrested Tuesday in the Tri-Cities and taken to the Spokane County Jail, where he is being held on a charge of first-degree murder.

At a news conference Wednesday, Spokane Police Captain Eric Olsen says investigators have seized many of Aguirre's electronic devices. He says information on those devices leads detectives to believe there are additional sexual assault victims.

Aguirre is charged in the slaying of Ruby Doss, a prostitute, in 1986.

He was arrested based on a recent DNA analysis that arose from an unrelated rape case in the Tri-Cities. Aguirre has pleaded innocent in that case.
