I found this article about Garrett Hughes, who’s been missing from Georgetown, South Carolina for seven years this month. Hughes was disabled from a head injury. He had seizures and memory loss, was partially paralyzed and couldn’t walk far. He lived in an assisted living facility.
Actually, there were several articles on this case, but the Georgetown Times one is the most detailed and has some quotes from Garrett’s brother. His brother believes another resident of the assisted living facility, who had a car, may have taken Garrett somewhere on the day of his disappearance.
I doubt Garrett is still alive. But he could, I suppose, be living in an institution in another state as a John Doe, or he could be homeless in some city. I wish he would turn up.
