Details were scarce — and a police spokesman, Sgt. Vincent Cole, declined to elaborate, saying investigators didn't want to alert the alleged assailant to what they know.

But "throughout the course of the investigation, detectives were able to gather enough evidence to name Joshua Bagley a suspect in her death," police said.

Cole would not say how or why investigators identified Bagley, or whether he had any connection to the victim.

On Monday Bagley was still on the run.

Police attempting to locate Bagley ask that anyone with information about the incident or Bagley's whereabouts call them at 602-262-6151, or contact Silent Witness at 1-480-WITNESS.
