FALMOUTH — Police on Monday said human skeletal remains were found off Route 100 Sunday morning, April 8, by a couple walking in the woods.

“We still don’t know if this is a man or a woman, how old they are, or how long the remains have been there,” Stephen McCausland, public information officer for the Maine Department of Public Safety, said Monday afternoon.

McCausland said the Office of the Maine State Medical Examiner is conducting an examination of the bones and there’s no timetable for when the work will be completed.

But he also said the remains don’t appear to be related to any open or cold homicide cases.

“Nothing stood out to indicate this was related to any unsolved (murder),” McCausland said, adding that the remains were also not found in what might have been a historic or old family burying ground.

McCausland said the bones were visible and that’s why the couple called 911. Falmouth police then called in the Maine State Police for assistance, he said.

McCausland would not provide any details about where the remains were found, but did say “they were fairly close to the Portland city line.”

He said there are no missing persons cases in Falmouth, but the state police are now expanding their search to surrounding communities.

“The public might be useful at some point,” he said, “but right now there are a still a lot of unanswered questions.”
