HONOR, Mich. (AP) — Authorities confirmed Monday that a body found near a cabin in northwestern Michigan was that of a 47-year-old Detroit-area woman who was reported missing in October.

A medical examiner didn’t immediately determine a cause of death for Adrienne Quintal, but investigators don’t suspect foul play, according to the Benzie County Sheriff’s Office.

Relatives of Quintal called authorities Saturday afternoon to report finding the body in a flooded area on the family’s property near the village of Honor, about 20 miles (32 kilometers) southwest of Traverse City.

The last known communication with the Southfield woman was about 2:30 a.m. Oct. 17 when she called a friend, according to her sister, Jenny Bryson. Quintal told the friend she had been in a shootout with two men near the family’s cabin.

Authorities found no signs that someone had been shot or injured, but evidence was found suggesting shots were fired out of the cabin from the inside. Quintal’s 9mm handgun also was discovered on the ground and her boots and cellphone on the roof.

The body found Saturday was in about 3 feet (0.9 meter) of water in an area where searchers had looked for Quintal. The ground around the cabin is swampy and nearly impassable in some areas, making a search very difficult, Benzie County Undersheriff Kyle Rosa said.
