In 2007, Chris Benoit, a wrestler who had allegedly suffered multiple concussions, killed his wife, his 7-year-old son and himself. Dr. Bennet Omalu, a doctor who examined his brain, diagnosed him with a severe case of CTE. He was the first professional wrestler to receive such a diagnosis. Later, Omalu diagnosed the same condition in another deceased wrestler, Andrew "Test" Martin, and he is examining the brains of three other wrestlers to see if there is evidence of the disease.
In 2008, the WWE instituted a concussion management program. However, the 17-count lawsuit says that the company was well aware of the dangers for a long time and did nothing. For example, it says that the company discussed the dangers of concussions in a scripted event as early as 1995.
