 The drunk driving suspect in a deadly crash at a New York City park that left three people dead is a substance abuse counselor. That's according to multiple sources, which also say Daniel Hyden wrote The Sober Addict, a book about living with addiction. The 44-year-old from New Jersey is accused of drunkenly speeding down a street, blowing through a red light, jumping the sidewalk, and mowing down people at a park as they were celebrating the Fourth of July last night. Hyden is charged with driving under the influence and is expected to face more serious charges.
