ARUNDEL, Maine (AP) — Police are investigating whether a woman with Alzheimer's disease witnessed or was involved in her husband's shooting death before she ended up in the woods, where her body was found Friday, investigators said.

The body of Matthew Coito, 63, was found Wednesday inside their home, and his wife was nowhere to be found. His death was declared to be suspicious, and authorities began searching for her. On Friday, her remains were discovered several hundred yards from their home.

Sue Kim Coito, 65, could be a suspect or a witness in the death of her husband when the investigation is concluded, State Police Sgt. Chris Harriman told reporters.

"We've narrowed it down to a couple of scenarios," he said at a news conference.

Investigators hope an autopsy planned for Saturday on Sue Kim Coito will provide additional answers as to whether Matthew Coito's death was a homicide or suicide, along with how she died, said Stephen McCausland, spokesman for the Maine Department of Public Safety.

The body of Sue Kim Coito was found in the woods in a swampy area covered in patches of snow, said Game Warden Lt. Kevin Adam.

The husband was serving as a caregiver for his wife, police said. Family members told state police they were aware of no problems.
