I got to know Mark a little over the years, I met him once, and have talked with him on the phone a number of times. We were first introduced when he headed Audio Alchemy, and I've done business with him at AV123. He was a warm, likable guy, though admittedly I did not know him well at all. It is sad to hear this.
That being said, if he did defraud people, especially with children,s charities as the rouse (or any charities for that matter), I hope he gets the harshest sentence the legal system can impose. I have no sympathy for that kind of bullshit. I'll give him the benefit of the doubt for now, but it's not looking good for him.
