No cause of death was determined from an autopsy completed Monday on a 46-year-old woman.
Coni Lee Shaw-Powell died Monday morning at Kadlec Regional Medical Center, said Benton County Coroner John Hansens.
She had been at the hospital since Dec. 11 after she was found unresponsive at a Pasco home. Shaw-Powell is suspected of having health complications, Pasco police said.
Hansens said the cause of death will have to wait on toxicology tests. Dr. Carl Wigren, a forensic pathologist from Seattle, performed the autopsy.

She worked as an optician at the Richland Walmart.
