The family of a woman found dead on I-95 in Florida last week is suing the man who claims she fell to her death off the back of his motorcycle on their first date. The Florida Highway Patrol says it is still investigating the death of 33-year-old Jennifer St. Clair of Fort Lauderdale. According to The Daily Beast, St. Clair's family filed a wrongful death lawsuit in Broward County accusing 34-year-old Miles McChesney of being impaired by alcohol when he was operating the motorcycle that St. Clair is believed to have fallen from. McChesney allegedly told investigators he would only talk to them if he's guaranteed full immunity. St. Clair's body is said to have been almost unrecognizable after being struck by several cars on the interstate.
