Spokane Major Crimes Detectives traveled to Tri-Cities this morning to take 51-year-old Richard Aguirre into custody for the 1986 homicide of Ruby Doss.

Spokane Police Major Crimes detectives took Aguirre into custody after a court hearing in Tri-Cities this morning. He will be booked into Spokane County Jail on the charge of 1st Degree Murder.

This arrest comes just over a month from when Aguirre was initially identified as a suspect in the nearly 3 decades old homicide. Detectives have been working tirelessly over the last month to ensure the best evidence is brought forward for this case. This included a number of trips to the Tri-Cities as well as tracking down witnesses from almost 30 years ago.

“Spokane Detectives still continue to review cold cases for new leads and evidence, so these perpetrators are held accountable for their crimes,” said Assistant Chief Selby Smith. “Because of the diligent work of multiple detectives and agencies over the last 30 years, we were able to present this case to prosecutors and help those affected by this tragedy.”

Detectives are still asking that any women who may have been assaulted by Aguirre, or anyone with information relating to the Doss homicide, contact SPD Major Crimes detectives at 509.622.5849.
