I was saddened to hear that Chris Kyle was murdered. He was a warrior and a hero.
He also left behind a family. As a writer, I can tell you that if I die, my wife is still going to be collecting my royalties as long as my books keep selling. So if you’ve not picked up a copy of his book American Sniper, you should.
EDIT: I was just told that the proceeds of his book all go to charity. http://www.mercuryone.org/ is taking donations for his family.
