Jonathan Josue Martinez was 19 when he left his Bonita Springs home on foot and was last seen on March 25, 2009. He had depression and required medication, but he did not take his medicine and may have been disoriented and unable to remember his name or other identifying details when he disappeared. His family did not report him missing until June 2009.

Jonathan is described as 4 feet 11 inches and about 130 pounds, with brown hair, brown eyes and a scar on his upper left arm. Investigators have struggled to develop leads, and age-progressed images have been released as efforts to identify him continue. If anyone has information on Jonathan’s whereabouts, please contact the Lee County Sheriff’s Office.
