I don't remember much, I just remember someone shooting and everyone running and running, screaming. Who did this to us? Why?

I remember my girlfriend being shot, she was hit in the back...I remember begging my parents to call for help...It's all a blur as I wrap my arm around her, she's breathing hard next to me. "Does it still hurt? Do you need a doctor?" I asked, apparently she and I just woke up and she'll be limping forever. I don't care, I love her.
