Twenty-nine years and tens of thousands of missing posters later, Richard Moreau still holds out hope that he can bring his daughter, Kim, home.
"It ain't about revenge, it ain't about nothing," he said. "Bringing my daughter's the only thing that's important to me."
With the help of Maine State Police and cadaver dogs, he thinks he may find her remains in the woods of Canton.
"I honestly felt that this day would come," said Richard Moreau.
Kim Moreau was 17 when she disappeared on the night of May 9, 1986, after spending time with then-25-year-old Brian Enman.
He was named a person of interest, but never a suspect. Police never had enough evidence to obtain a search warrant for his property - until this week.
Investigators are using ground-penetrating radar and K-9's, but haven't explained the sudden progress in the case.
Over the years, the case had seemingly gone cold, but her father kept working, putting missing person signs all over the state - including one right across the street from Enman's property.
"I did it intentionally," he said bluntly.
Richard Moreau estimates he has put up more than 50,000 posters since his daughter's disappearance. If Friday's search turns up nothing, he says, all he knows is that it's time to put up even more.
Necn's attempts to reach Enman were unsuccessful. Earlier, he told a local newspaper that he had nothing to do with Kim Moreau's disappearance and that police are grasping at straws.
