I NEED YOU ALL....

This is so unreal..i want someone to pinch me and wake me up out of this nightmare. We had a blackout last night and my son asked if he could sleep over his friends house who lives next door. I said it was fine, because we were going to go to the pool today. So...apparently they snuck out to go to his girlfriends house who invited them over to watch a movie. They at first didn't want to go because her dad was home. He's a correction officer. But..they went anyway and stood in the basement. Her father caught her and my sons friend. My son was in the bathroom when he came down. He started screaming at her and his friend and then proceeded to hit her. My son says he freaked out and stood in the bathroom. His friend left the house and came back home. The whole time my son is in the bathroom in the basement, he says there was a lot of fighting going on upstairs and then a loud thud. At 7:30am I was woken up by detectives notifying me my son was missing. I told them how could that be when he was next door?? They told me about an incident that had occured and asked me to check for him..which I did and he wasn't here. They went back to the house and found him at still in the bathroom and he was crying. His girlfriend (15 yrs old) apparently got hold of her fathers gun and shot herself in the chest (which was the loud thud) and died this morning. I am in shock..and can't even begin to tell you all how I am feeling. I knew, and cared for this girl. I just spoke w/her and her father last night..because he came to lend us flashlights since we had a blackout. And now I hear this...I don't even know what to do..say. My son is not saying much...but I know he is very very sad. I hate that this happened..and although I know they are teenagers..I wish they would have never gone over there, because maybe this wouldn't have happened. Apparently there were alot of other problems their family had (which she never let on), and I guess it lead her to do this. Her father was VERY over protective of her..which is understandable...but now he is being questioned because of her getting a hold of this gun. This is a tragedy...one that I don't know how I or her family are going to be able to overcome. I need your prayers ladies...please.
