Zachary Hartwell's parents allege the stuntman was "reckless and negligent" for getting behind the wheel of his Porsche and driving at high speeds while under the influence of alcohol, according to TheWrap.

A police report indicated Dunn's blood alcohol level was more than two times the legal driving limit when he crashed his sports car in West Goshen Township, Pa., in June 2011.
