The Cumberland County Sheriff’s Office is asking for help finding a 73-year-old Harrison man.

Police are looking for Arthur Lewis, who they say left his home on Wednesday morning around 6 a.m. His wife says he left driving his red, 2017 Chevrolet Colorado pickup. Police believe he suffers from mild dementia and may be lost or confused. His intended destination is unknown.

Arthur is a white male, 6 feet tall, weighing 210 pounds with balding grayish-brown hair and brown eyes. He was last seen wearing blue jeans, a gray long-sleeve t-shirt and a gray hooded jacket. He also wears prescription eye glasses. Police say he does not have a cell phone.

Authorities activated a CodeRED alert to residents and businesses in the area, and were working Thursday afternoon to activate a silver alert notification.

Anyone with information is being asked to contact police.
