HONOR, Mich. (AP) — Police turned to a drone and dogs to try to solve the disappearance of a Detroit-area woman in northern Michigan, but the latest search didn’t result in any new findings.

TV station WPBN reports that the search Tuesday was focused on a half-mile radius of a cabin in Honor in Benzie County. Adrienne Quintal of Warren was reported missing last week. Police say it could be a case of foul play.

State and local investigators used a drone to map the area and keep track of where they’re searching.

The 47-year-old Quintal called someone in the Detroit area for help early last Thursday. Deputies found her car, purse and phone at the cabin.

Anyone with information can call 231-882-4487.
