“Obviously, this is an important case, and we are doing what we can to solve it for the family,” said Kent County prosecutor Chris Becker.

In February, the 40th anniversary of the girl’s disappearance, Deanie’s mother said she yearns for answers.

“I’m 74 years old,” Mary Peters told WOOD-TV. “How many more years do I have left before they find something, or are they never going to find something? I’m running out of time.”
