A former engineer for BP has been arrested and charged with obstruction of justice for deleting text messages related to how much oil was flowing into the Gulf of Mexico from the Deepwater Horizon spill in the spring of 2010. Kurt Mix, of Katy, Texas, is accused of deleting hundreds of text messages from his iPhone that he exchanged with a co-worker and a contractor. These are the first criminal charges brought against any worker involved in the accident.
