Detectives investigating the case of a woman found seriously injured on a Whitman County road have secured evidence and questioned several people, including the victim’s boyfriend.

Kristen E. Grindley, 23, remains in critical condition at Sacred Heart Medical Center. She’s been unconscious since she was found in a pool of blood on Pullman-Albion Road about 1:40 a.m. Wednesday.

Investigators think she fell from a vehicle or was hit while in the road.

“We do have a vehicle in mind,” said Whitman County Sheriff Brett Myers. “We have had that vehicle since shortly after the incident.”

Grindley graduated in May from Washington Sate University, where her boyfriend is believed to be a student, Myers said.

Detectives have applied for search warrants and will be reviewing cell phone call histories, Myers said.
