At an LA Fitness gym, there was a devious incident which occurred that included the killing of three people.George Sodini was said to have been the gunman involved in the incident and he has stated proudly that he would not be ashamed of anything of his that is published, as he would be dead, anyway.
Allegedly, George was influenced by relationship guru, R. Don Steele's book, For Men Over 35. He was seen in a seminar that was held by Steele, and he has even taken part in confidence building exercises at these very seminars.
