Elderly man missing; tan jacket, gray cap

I lost my grandfather yesterday around 6pm in Lewiston. He’s 72, about 5'6" with a slender build, salt-and-pepper hair, and rectangular glasses. He was wearing a tan knee-length rain jacket, a gray knit cap, and brown loafers. He also has a small turtle tattoo on his left wrist and uses a wooden cane with a bright red handle. I last saw him near the Lewiston City Library on Main Street, heading toward the 3rd Street intersection and then toward the downtown market—he can get disoriented in crowds and tends to wander slowly. This is really hard on us—he has medical needs and sentimental value to our family. If you spot him, please help us bring him home.
