Johnny Lamar Brown, 43 and described as a dependent adult, vanished from Myrtle Beach, South Carolina, on August 5, 2012, while on vacation with his family from Cartersville, Georgia. He was last seen near an ice cream shop by the Sea Crest hotel on South Ocean Boulevard, reportedly speaking with a woman. He left without his wallet or other personal effects and may have had only his hotel room key.

Johnny is a Black male, about 5 feet 6 inches to 5 feet 7 inches tall and roughly 140 pounds. He has a severe speech impediment, becomes easily confused, fears thunder and lightning, and dislikes being touched or approached quickly by strangers—factors his family says make him particularly vulnerable. There were unconfirmed sightings in the Myrtle Beach area soon after he disappeared, and his family believes he might have tried to return to Cartersville, but no concrete evidence has been found.

Anyone who was in Myrtle Beach around August 5, 2012, or who may have seen Johnny that day is asked to come forward with information.
