"I think it started outside. He tried to get into the house. The person must have followed him in here," said Jean Stafford, Walker's sister. "I was in my room and we heard the shots. The shots came up here. The main thing I wanted to do was try to get with him and try to help him because he was covered with blood.”
Stafford said her brother served in both the Air Force and Navy.
