HELP MY LIFE IS AT RISK!!!!!!!!!!!!!!!!?

There is a criminal in my town. I saw on the news taht you should contact 911 immediately when you see him. So surprisingly, I went to walmart to which I saw him in the parking lot. I was in m ycar. I called 911 and told them but he saw me and in his eyes I knew that he knew that i was calling 911. He then looked mad. I immediately drove home but the police are saying that they don’t have a track of him and I fear he may of followed me home. We have a pistol here at home but the firing pin broke and I’m getting it fixed so we have no defense. HELP ME MY WHOLE FAMILY MIGHT GET KILLED
