From my understanding they cant or suppose to kill you out a blood gang at that age, females are not shot , or maybe she didn't come to the meeting, I don't know., but same time it not being enough to be shot. This was a dislike dispute.
The best thing to do in those time is find the girl blood gangs which should have not been as hard to do, they are not very deep or hard to miss.. Check her school year book, you should find a few in there, a lot same folks from school area didn't show up that week.. Its not hard to miss. A few should've be around the corner from her. time has elapse so much they may be long gone..
The last bet for them is find some who were in the gang from her area and question them in the prisons. I think her best friends know who did it. they was at the party. They know who she left with.
sorry to be off topic
If you ask, Le ruin a lot cases playing the waiting games in them, trying to find every single person, they had a few suspects or POi . LE sometime is out right scared to make an arrest in them. They could've put a decoy in the school that same week or in her area and heard the whole matter detail for detail. Arrest whom ever, they will talk are some hard time
