I'm disgusted at some of these comments and at people's ignorance and lack of compassion. I'll keep it clean, though. Clark was not a "nut job". He was a beautiful man with a kind heart. People can't control having mental illness or developmental disabilities any more than someone can control having Diabetes or Cancer. Mental illness does not define a person. I will define Clark for you. He was honest, generous, loving, friendly and funny. He made me smile every time I saw him. Please refrain from negative comments. Clark had parents, sisters and other family and friends who loved him. Derogatory comments, especially during their time of grief, are rude, immature and unnecessary. Let him rest peacefully, please.
