The prime suspect in last year’s slaying of a popular Atlantic City casino supervisor admitted in court today that he committed the crime. Mark McGee was in court and pleaded guilty to charges that he fatally shot 57 year old Ray Kot at the Trump Taj Mahal in 2009. Kot worked as a gaming supervisor, and McGee says he killed Kot because he felt casinos electronically changed table games. McGee will likely have to spend 30 years in prison before he becomes eligible for parole.
