Case closed: No charges filed in fire that left a mother dead

WEST RICHLAND, Wash. -- West Richland Police still do not know what caused a fire last year that left a mother dead. Prosecutors decided not to file any criminal charges Thursday related to the fire, death or a possible sexual assault.

Police said this does not prevent them from investigating the case further if new information comes to light.

Sandy St. George was killed by a fire at her home on the 700 block of S. 45th Ave. in West Richland last March. Her husband escaped. Three-children were staying somewhere else when the fire started.

The cause of the fire has never been determined. The coroner also listed her autopsy results as "inconclusive."

Thomas St. George was accused of having an affair with the couple's young babysitter. He denied any wrongdoing in regard to the teenager or the death of his wife.

Multiple agencies worked together to investigate this fire during the last year and a half.

West Richland Police plan to hold a news conference at 2 p.m. Friday at the West Richland Council Chambers regarding this case.
