Police in the southern part of the state are investigating a pair of deaths while also searching for a missing woman.

State police say the death of an Arundel man found dead inside his home Wednesday is suspicious and the man’s wife is unaccounted for.

Relatives found the body of 63-year-old Matthew Coito in the kitchen of his home on Campground Road on Wednesday afternoon, police said. Troopers and York County sheriff’s deputies have been searching the wooded area near the home for any sign of the wife, 65-year-old Sue Kim Coito, who police say has Alzheimer’s disease.

Police described Kim Coito as 5 feet 2 inches tall, weighing 130 pounds and with black hair and brown eyes. If she is not located Wednesday night, an expanded search will take place Thursday, according to a news release from Stephen McCausland, spokesman for the Maine Department of Public Safety.

The couple had not been seen or heard from since early last weekend and relatives went to check on them Wednesday, according to McCausland. After finding Coito’s body inside his home, they called the York County Sheriff’s Office.

In Sanford, state police are working with Sanford police and the Maine Warden Service after a woman’s body was discovered along Hancock Way off Route 109 Wednesday afternoon.

The body is not that of the the missing Arundel woman, according to McCausland.

The body was found by Warden Sgt. Tim Sphar, who has been involved in the search for Kerry Rear, missing from Sanford since mid-January. The positive identification and cause of death will await findings from the State Medical Examiner’s Office on Thursday, McCausland said.

According to the news release, Rear’s family has been notified of the discovery. The location of the body was about half a mile from where Rear was last seen.
