Gwinnett County police say Kai Yee was located at a family friend's house in Lawrenceville and was returned home safely.
Yee's mother had told police he had wandered away before, but has always returned home.
Kai Yee apparently became upset and walked away after he was verbally disciplined by his mother for acting inappropriately while on an outing at the park.
