Tyler was a young kid, 21, presumed to be the starting QB next season for Washington State. He committed suicide today, via gunshot to the head and left behind a suicide note. This reddit thread has a lot of commentary and tweets/releases surrounding the event. In reading through these things, I cannot find a concise reason for the suicide other than what people are suspecting to be mental illness (such as severe depression), but that's not proven beyond speculation.
Rest in Peace Tyler, many thoughts and prayers for you and your family. You will be missed.
