The first time I heard about him I thought the guy telling me was lying about it or pulling my leg. Then he told me during his interview process one of the people in our company asked him if he had anything in his background like being a convicted ax murderer?
At that point I called "bullshit" on it and he said go ask Charlie, he is the one who asked me. So I phoned Charlie and he sure enough told me the story and said google it yourself.
My sickness comes from the idea that this guy wasn't using a fake name or anything and he gets hired on at the company and then they are "surprised" about it. A criminal background check should have exposed that in a heart beat when just a regular Google search did. That is the sick part for me, along with the murder.
Thanks for the congrats and in answer to your question about if "those people know?" Nobody has a clue where he went to work after he left our company so I don't have an answer for that question.
