MAPLE GROVE, Minn. -- Both police and Amy Sue Pagnac's mother are working under the assumption that anything is possible, including that the missing girl could still be out there...alive.
"People wonder why I believe Amy is still alive. It's not just because of the girls in Ohio that were found, or any of those previous ones, it's because there is no evidence that she is gone, meaning dead," says Susan Pagnac.
Though police are searching Susan's home right now looking for clues in the case, they too acknowledge that with the lack of evidence to the contrary, they have to assume it's possible.
"If she's alive and she's in another state, just please call us so we can touch base with you," says Capt. Keith Terlinden with the Maple Grove Police.
Capt. Terlinden says they've never stopped working Amy's disappearance. The last time she was seen was August 5, 1989. She had taken a trip up North to family property in Isanti County with her adoptive father Marshall Midden. Marshall is married to Amy's mother Susan and he adopted Amy when she was a small child. Marshall says the two stopped at a gas station in Osseo on the way home, he went inside, when he returned, Amy was gone. It has been 25 years of following tips and leads, and just this week, it lead investigators back to her childhood home.
"It's not a specific piece of information, it's more of a process that brought us to their house," says Capt. Terlinden.
Investigators will not comment on what exactly it is they are looking for or how long it will take.
"We have a goal in mind within the search warrant and we'll leave once that goal has been accomplished," says Terlinden.
Susan Pagnac and Marshall Midden are not considered suspects at this point and Susan actually welcomes all the attention to her daughter's case.
"They are doing something, they are doing something, it may not make sense to me but they are doing something. If this is the thing they have to do to get to the next step and the next step, then we'll do it," she says.
As for the questions about Amy being buried somewhere on the property, Susan says it's absurd.
"I know they will not find Amy there because Amy was last seen at the gas station by my husband."
