Question:

I need help on my story...??? i think that my story is a really common story...can someone give me ideas? thnx

my story is about a young girl who sees the death of 2 innocent teens and also gets a glimse of the shooter, she runs off, scared to death but doesnt tell anyone. the shooter catches the girls name cos of the name tag and tries to kill her but couldnt find her. 7 years later the girl is in a univertiy but one night she suddenly runs over one of the professors while her friends escape from that same teachers house cos they were changeing the scores of their tests. now the girl is really scared and leaves town and goes to london. then 3 years later she comes back for a friends wedding. she feels that she's being watched and starts getting scared when weird things start happening at the hotel that she and her friends stay at. suddenly one of the friends says that he has seen the teacher who they killed alive.. i have and idea something along that..can anyone give me ideas on how to make a really good ending...like i was thinking that the teacher who was killed was the teen who shoots ??
