A jury found Colin Gray responsible for the alleged actions of his teenage son, who is awaiting trial on charges of killing four people during a shooting at a Georgia high school. During the trial, Gray said he bought his son, Colt, a rifle for Christmas when he was 13 years old. The following year, Colt allegedly launched his shooting spree. Colt has pleaded not guilty. The father took the stand in his own defense and said he never thought his son would commit a crime.
