Answer:
He was trapped inside the game
Explanation:
He is the confirmed killer of 11 children. His story is told through 8-bit-styled minigames in Five Nights at Freddy's 2, Five Nights at Freddy's 3, a cameo in Five Nights at Freddy's 4 as well as hints through Sister Location .Later on in the franchise, when the Virtual Reality game came out, he is trapped inside the game as a character known as Glitchtrap. He is also the father of Elizabeth Afton and Michael Afton. I dont think he died.
In the first five night of freddy's:
While William Afton is not seen in this game, he is referred to in newspaper clippings. He is described as an employee dressed as a company mascot that lured two children on the night of June 26th into a backroom. Sometime after, five children were linked to the incident, and while the suspect was charged, the bodies were never found. Go to william afton fandom and you'll see how and why.
