BOWDOIN, Maine — A Maine Warden Service plane was headed to Bowdoin on Wednesday afternoon to help search for an 85-year-old man reported missing just before 3 p.m.

Family members of John Tarr Road resident Guy Kittle, who suffers from Alzheimer’s disease, reported that Kittle left his home for a walk and hasn’t been seen since, Eric Sawyer, director of the Sagadahoc County Emergency Management, said Wednesday.

Crews including deputies and a police dog from the Sagadahoc County Sheriff’s Office, as well as members of several area fire departments, initially conducted a search around Kittle’s home and nearby roads.

Sawyer said the warden service plane left Greenville and was due to arrive in the Bowdoin area just after 4:30 p.m.

Kittle was likely wearing a tan coat, although Sawyer said it’s unclear whether the coat was warm enough for Wednesday’s temperatures.

He said additional volunteers had not been requested as of 4:30 p.m.

Kittle was the subject of a previous search in September 2014 after an all-night search by the warden service and local sheriff and fire departments. He was found just after 7 a.m. the following morning at a private work site between Adams Road and Lewis Hill Road, officials said at the time.
