UNION — Maine game wardens say a pair of surveyors found an elderly Maine man with Alzheimer’s disease who went missing overnight in the Union area.

Wardens say 75-year-old Gerald “Pete” Brooks of Union left home to go for a walk at about 11 a.m. Tuesday and was reported missing several hours later.

He was found Wednesday morning in good health.

About 130 people from a variety of agencies participated in the search. Wardens used an infrared camera system, aircraft, search dogs, professional search teams and volunteers.
