HONOR, Mich. (AP) — A Detroit-area woman remains missing after a weekend search with police, dogs and volunteers in the northern Lower Peninsula.

Trail dogs picked up the scent of Adrienne Quintal, but cadaver dogs did not, said a sister, Jenny Bryson.

“The search dogs were amazing,” Bryson said Monday on Facebook. “Not able to cover as much area as we wanted because it’s so marshy/swampy up there. Possibly going up in the next couple weeks to rule out some more areas. Much is dependent on weather.”

Quintal, 47, was reported missing in October from a family cabin near Honor, about 20 miles southwest of Traverse City, in Benzie County.

Bryson said Quintal called a friend in the wee hours on Oct. 17 to say she was involved in a shootout with two men who were outside the cabin. Investigators found multiple bullet holes in the empty cabin and shell casings on the ground from what appeared to be multiple guns.

Search teams were out Saturday and Sunday.

“It is a rough swampy area, and it’s difficult,” Benzie County Sheriff Ted Schendel said.

Quintal’s family is offering a $10,000 reward for information that solves the mystery.

“She did have a head injury from a while back that may have triggered something, and she may have run off into the woods. We just don’t know,” the sheriff told WPBN/WGTU-TV.
