David McCarthy admitted to striking and killing Melissa Lech in a hit and run accident three years ago. He was arrested in a bizarre set of circumstances following a hit and run apology when he apparently went to the home of Lech's sister and confessed to the crime over the weekend.
Now a review of McCarthy's driving records show a history of reckless driving previous to killing Lech as well as a drunk driving episode following Lech's death, reports the Chicago Sun-Times. It wasn't reported if McCarthy is suspected of driving under the influence at the time of Lech's death.
