Cops are searching for Adrienne 'Ada' Quintal, from Michigan
Quintal was last seen at a cabin in the village of Honor, in Michigan
Her friend then called the police, who arrived at 2.58am, just 13 minutes after the first call was made.
But when officers arrived at the cabin in Honor, 250 miles west of her Detroit home, they found no one there.
'POSSIBLE FOUL PLAY'
Cops said they had "observed evidence of possible foul play" but weren't sure whether Quintal – who goes by Ada – was "missing voluntarily or in danger".
The missing woman's mobile phone, purse, keys and vehicle were all left at the cabin, WPBN reported.
Her son Nick White told Fox 2: "He was up there with her, he came home to drop supplies off, we are working on the condo here.
"She was also just getting ready for hunting and hanging out and enjoying the wildlife."
Nick said his mum's boyfriend, who has not yet been identified, had returned home to on Wedneday to her home in Southfield, Detroit.
Cops have searched a swampy area surrounding the cabin and have interviewed her boyfriend.
They've now launched a $5,000 (£3,900) reward for information that could help to find her.
