Why was Lindsey Williams deleted from wikipedia?

I really don't know who Lindsey Williams is, my guess is a controversial (conspiracy theorist?) old reporter from what I can gather. But what I want to know is what would cause wikipedia to delete him from the wikipedia website? Anyone know?
Update: Well, apparently he was on there. If you google his name and wikipedia it says wikipedia has deleted this, or whatever...
Update 2: nevermind! Found my own answer. Lack of reliable resources by author. Thanks anyway.
Update 3: oh, perfect. Thanks babybishops! I'll probably pick you as best answer when I can:)
