Cannon was last seen at his residence in the 12600 block of Weir Street in Omaha, Nebraska, sometime in March 1995. At the time of his disappearance, he was involved with the Rainbow Family, a nomadic religious group. He has not been heard from since. Cannon was not officially reported missing until May 2004—due to law enforcement initially refusing to accept a report. Few details are available regarding his case. He is a Caucasian male with dark brown hair and gray/hazel eyes. At the time of his disappearance, his hair was buzzed with bangs. He had no tattoos, but his ears were pierced. He was known by the nickname "Ben."
