Over a month after a Michigan woman mysteriously vanished, authorities appear to be making some progress in the investigation.

As CrimeOnline previously reported, Adrienne Quintal has not been seen since October 17 when she was staying alone in a family-owned cabin in Honor, Michigan. Her boyfriend had been staying with her but had left two days before she vanished.

In the early morning hours of October 17, Quintal, 47, called a friend to say that two armed men were outside the cabin, and that she had shot one of them in the face. The friend called police, who were somewhat delayed due to an error in the reported address. When they arrived to the cabin, Quintal was gone but her car and her possessions had been left behind. Police reportedly found her boots and cell phone on the roof of the cabin, and her gun was on the ground next to the home. Authorities reportedly found evidence of shots having been fired from inside the home, but no evidence that anyone had been injured.

According to the Traverse City Record-Eagle, Lt. Troy Lamerson of the Benzie County Sheriff’s Office said that law enforcement agents have been interviewing people who know Quintal, including her adult son and her boyfriend.

The boyfriend, who has not been publicly identified, has been named a person of interest in the investigation, Lamerson said.

“We’re learning more every time we talk to them,” Lamerson told the newspaper, adding that Quintal’s family “believes she is being held against her will.”

The family is now offering a $100,000 reward for information about Quintal’s disappearance, and Lamerson said this has prompted a number of tips.

At least one of these tips appears credible, Lamerson said. The possible witness reportedly told police they had seen someone matching Quintal’s description and provided a specific time and location. Authorities are working to review security camera footage that may help corroborate the tipsters’s account, according to the report.

Investigating authorities are reportedly organizing a search of the woods surrounding the cabin to begin next week, and will use the aid of canine teams.

Anyone with information is urged to call Benzie County Central Dispatch at 231-882-4487 or the Michigan State Police silent observer line at 1-866-774-2345.
