A 75-year-old Union man was found safe and sound May 12 nearly 24 hours after he walked away from his home.

Gerald “Pete” Brooks was found about 10 a.m. off Hart Road in Warren by a surveyor, said Knox County Emergency Management Agency Director Ray Sisk.

Brooks had been reported missing the afternoon of May 11. He lives on Route 17 in Union and is known for taking long walks every day. He left his Union home to go for a walk at approximately 11 a.m. on May 11, and was reported missing by family at approximately 4 p.m., according to Lt. Kevin Adams of the Maine Warden Service. He was last seen at about 4 p.m. on Folger Road around the Union-Hope line.

Brooks was wearing blue jeans, a blue flannel shirt, a navy blue windbreaker jacket, and a tan baseball cap. Temperatures dropped to about 32 degrees overnight.

The Maine Warden Service led the search, with help from volunteers from Maine Search and Rescue, Maine Search and Rescue dogs, the Union Fire Department, and Waldo County, Lincoln County, and Midcoast search and rescue teams. They began looking for Brooks on May 11 at around 9 p.m. The Hope Fire Department was also called in May 12 to help with the search.

The search started off Folger Road in Hope, near the Union-Hope town line. A command center operated out of the Union Fire Station.

The Maine Warden Service used its new thermal imaging camera system from a plane, and had been flying over the area since 5:30 a.m. on May 12.
