Kayaba, the man who made SAO, had to have a internet connection to play the game. Was it ever explained why he was never caught?

He had an accomplice Koujiro Rinko, who has not yet appeared in the anime adaptations. She took care of his body in a small cottage in the mountains. She’s arrested shortly after his death, but due to apparently being forced to help under threat of death she’s acquitted.

She’ll show up for sure in the next arc, where she’s a fairly important character.
