SPOKANE, Wash. -- Former Pasco officer and murder suspect Richard J. Aguirre appeared in court on Friday in Spokane County. His trial has been delayed until April 4, 2016.
Aguirre plead not guilty to all charges against him in July 2015.
Aguirre faces charges for First Degree Murder, Tampering with a Witness and Voyeurism in Spokane County. He is also facing a separate rape charge in Franklin County.
Aguirre is accused of the 1986 murder of Ruby Doss. Ross was found strangled near the intersection of N. Fiske and E. Ferry in Spokane.
Detectives believe that Aguirre and Doss got into a fight after a sexual encounter on the night of the murder. They say Doss pulled a knife on Aguirre then tried to run away. They believe Aguirre caught her and hit her twice on the back of the head. Once she was unconscious, detectives believe he strangled her.
Police identified Aguirre as a suspect through a DNA profile match.
The match came when investigators were looking into an ongoing rape case in Franklin County. They matched the DNA they collected from Aguirre in the Doss investigation to the Franklin County case.
