Manuel Colio was 94 when he was last seen on April 6, 2007, in Concord, California. He was living in a homeless shelter at the time; staff reported seeing him that day but there has been no sign of him since. Manuel is described as a Hispanic male, 6 feet 2 inches tall, about 145 pounds, with black hair.

His disappearance is worrying given his advanced age and the complete absence of communication or confirmed sightings. Very few leads have surfaced and the case remains unsolved. If anyone knew Manuel, saw him in Concord around April 6, 2007, or has information about where he might have gone, please share what you know.
