Roscoe Pond: "Dateline" 21 Security Camera footage erased after wife goes missing

DATELINE on NBC. Did you watch last night's episode called, "The house on Sydney's cove?." What a sad, sad episode. A husband has 21 security cameras in and outside his home. All of it placed to spy on his wife and family. He is a controlling and manipulative man who says his wife was abusive and unstable after she goes missing.
