22 year old nebraska drunk driving accident into tree

My son was out with his friends at a bar in Nebraska, on his way home from the bar he was driving drunk. He swayed into a tree which had ended his life, I will never know why he did what he did. I hope that this teaches other kids about the bad effects of driving drunk. He just made a bad choice, which turned out to be very bad, our family is very sad because we will never be the same without him.
