The Washington State Patrol says a medical event is to blame for an accident that sent a missing woman’s car down an embankment on US Highway 12 North of Oakville. Her 1993 Chevy Lumina drove off the eastbound shoulder and was discovered near milepost 33 around 1:33 pm Sunday afternoon.

Trooper Megargle said the car struck two trees 30 feet down an embankment and was found perpendicular to 12, facing the highway. The driver, 70-year-old Sharon Lee Leaming was airlifted to Harborview Medical Center with undisclosed injuries. She had been reported missing out of Rochester last Tuesday.

The Thurston County Sheriff’s Office said Leaming left her Rochester the morning of the 23rd and was headed to a family property in North Cove. A friend reported that she left the North Cove property Tuesday because her back hurt. She intended to return to Rochester but didn’t make it home.

The Pacific County Sheriff’s Office got a ping from her phone in the Oakville area and a family member tracked it to a home off of US Route 12 in Oakville. Searches in both areas failed to locate her.
