I can't get Christina out of my thoughts since I first heard about her. I've been drunk and stupid in Shops of Legacy many times and can't help but think it could have been me. I'm wondering if EA didn't harm her intentionally; that perhaps it started out "innocent" enough then something happened which caused him to panic and try to cover himself.
She got in the car with him for some reason. He makes a pass at her and she gets mad and gets out of the car, he accidentally hits her. He panics and puts her in the trunk thinking shes dead. He drives somewhere to dump her body and discovers shes not dead and finishes the deed, hence the bite marks and bruises.
They go for a ride so she can try some new drug and she has a bad reaction and dies. He dumps her somewhere. Her "friends" keep their mouth shut because they don't want to get linked back to drugs.
I pray she gets found soon. I can't imagine her familys pain.
