Authorities are continuing to look for a Virginia boy who went missing while he was home alone more than 10 years ago.

Quinn R. Woodfolk was 11 years old and had been by himself at his Charlottesville home on July 4, 1988. He was gone when his father came home, and authorities don’t know where Quinn went or why he disappeared, said Melinda Stevens, director of the missing children’s division at the National Center for Missing and Exploited Children.
