Missing 6 year old in FL

Nancy Grace has on tonight and talking about a missing 6 year old boy in FL. He is disabled and has a mind of a 2 year old. They don't know if it is an abduction or if he just went out to play. They have searched. He can't speak or understand English. I feel sorry for his family. Grandmother found him gone after found missing when playing with friends. Why would you let him out to play if he has the mind of a 2 year old. They are using over 150 officers. I pray for his family and him. May they find him safe. He was lost on Saturday. Poor baby.
