Mark was my best friend at Canon Mac Sr High. I only heard about this today. My condolences go out to family and friends of Mark. Even though years went by between visits, he and I could still strike up a conversation about our shared interests. He will be missed.

I went to high school with Mark and we kept in touch a bit via Facebook the past few years. I am so saddened by this unexpected news. I always look for his name in movie credits...and imagine I still will.
