New clues in Maine teen's 1986 disappearance?

CANTON, Maine -- Cadaver dogs gave several indications that human remains were on land adjacent to property owned by one of the last people to see a Maine teenager alive nearly 30 years ago, and investigators plan to return there "in the near future" to resume the search, a state police detective said Monday.

State Police will meet this week with geologists before determining the next step after four days of searches on and around Canton property owned by Brian Enman, said Sgt. Mark Holmquist.

"We remain cautiously optimistic," he said. "This case in particular is challenging because it's 29 years old. Essentially it's trying to find a needle in a haystack. It's a big challenge."

Kimberly Moreau, of Jay, was 17 when she disappeared on May 10, 1986, after going out with a group that included Enman, police say. Enman has denied any involvement in her disappearance, and he has never been charged with a crime in the case.

Moreau's father, Richard Moreau, said Monday he's confident state police are getting closer to solving the mystery of his daughter's disappearance.

"The best way to describe this is putting a 10,000-piece puzzle together. We've got to have the final piece to tell us where the body is," the 73-year-old said.

He told CBS affiliate WGME the family is anxiously awaiting news.

"We're thinking that this can finally be the time that Kim is going to finally be found and brought home," he told the station.

The search of the property appeared to be a big break.

State police obtained a search warrant, and Moreau said he was told that there was new evidence in the disappearance.

Police spent four days searching Enman's land and nearby woods with ground-penetrating radar, cadaver dogs and even a backhoe. Medical examiners and University of Maine geology professors were part of the effort.

The land was owned by someone else in 1986, but Enman later purchased it. He filed a building permit in 2004, and there's a home on the property. Holmquist declined to say what made investigators zero in on the land.

Richard Moreau said he only wants closure.

He said his daughter was with Enman and another man and a friend, Rhonda Breton, before she went missing. Breton has since died.

Enman told the Kennebec Journal that he and the other man drank alcohol and did cocaine together that night. He said he dropped Kim Moreau off near her home, and that's the last he saw of her, he told the newspaper.
