CROWN CITY, Ohio -- The FBI has joined the search for a missing Ohio couple.

Willard Frye, 76, and Patty Frye, 72, went missing Thursday. They were last seen driving away from a gas station in East Lynn, W.Va., and heading toward Wayne, W.Va.

They both have Alzheimer's disease and Patty is a diabetic. Family members said they do not have their medication.

They were driving a dark blue Ford Focus with Ohio plate DEZ-5765.

Willard walks hunched over, is bald with some white hair and has blue eyes. He frequently wears ball caps.

Patty is 5 feet 4 inches with straight brown hair and brown eyes.

Family members said Patty would be driving if they are in the car.

The couple has been living in Crown City, near Huntington, W.Va., but has strong ties to northeast Ohio.

Willard and Patty lived in the Cleveland area for about 50 years. Until about three years ago they lived in Grafton.

Willard is retired from the Ford plant. They attended Christian Unity Church in Grafton for over 30 years. They still have family and friends in the area and they considered it home. The family feels they may have gone back to the area or are trying to do so.
