Helena Ann Negrete, known to family as Ann, disappeared from the Gwinn, Michigan area on the evening of June 14, 1997. At about 5:30 p.m. she went for a customary walk from a residence in the 2700 block of County Road 456 and was last seen walking down the driveway. When she had not returned after roughly thirty minutes, family members searched and could not find her.

Helena was 45 at the time, petite at about 5 feet 5 inches to 5 feet 6 inches and 100 to 110 pounds, with shoulder-length blonde hair and blue eyes. She wore a white sweatshirt with a pink heart and green trim, light blue jeans with a hole in one knee, white tennis shoes with blue accents, and a red and black head scarf. She also wore distinctive jewelry including a bracelet spelling Ann in diamonds and a ruby-and-emerald piece trimmed with diamonds. Family reported she had a stutter and may have had early signs of dementia.

Extensive searches of the rural area surrounding where she was last seen have not produced clues, and no one has reported hearing from or seeing Helena since that evening. Does anyone who lived or walked in the Gwinn area in June 1997 remember seeing her or have information that could help locate her?
