Matthew W. Coito, 63, was found dead inside his Arundel, Maine, home on Campground Road on March 8, 2017, after relatives checked on him and his wife following several days of no contact. State Police described the death as suspicious; an autopsy later confirmed a gunshot wound as the cause of death. Authorities reported no signs of a break-in at the residence.

Matthew’s 65-year-old wife, Sue Kim Coito, who suffered from Alzheimer’s disease, was missing from the home when he was found. Their dog was alive inside the house. Two days later, on March 10, Sue Kim’s body was located in woods about 375 yards from the couple’s home; investigators said she likely died from exposure. Police indicated they had narrowed possibilities and believed no one else was involved other than the husband and wife. No arrests or outside suspects were announced.

Are there any neighbors or visitors who remember seeing the Coitos in early March 2017 who might help fill in what happened those final days?
