Isaac Carlos, 68, was last seen on March 4, 2017, when he left for a walk in Sells, Arizona, on the Tohono O’odham Nation. He is an American Indian / Alaska Native male with gray or partially gray hair and brown eyes, about 5 feet 4 inches tall and 140 pounds. At the time he vanished he wore a hat, a brown flannel jacket over a purple t-shirt, and blue jeans.

Family reported that Mr. Carlos had a history of wandering off, which raised particular concern when he failed to return from the area of Federal Route 19 and Main Street. The Tohono O’odham Nation Police Department opened a search and investigation, but the reservation’s large, sometimes difficult terrain has complicated efforts.

If anyone saw Isaac on or after March 4, 2017, or has information about where he might have gone, please share what you know.
