Motive map - I like that, Mamamerced. He was the only one with her and he did something to make her really mad, so mad she fought him. If there was blood in the garage, then I'm thinking he must have hit her first (blood out of her nose/mouth), maybe even knocked her out cold...then panicked, and put her in the car. I'm thinking she came to, started to fight him and that's what made him crash the car. Then he really lost it. IMO this is how it worked out. I think the others kept quiet because of their participation in the night with drugs. I just wonder what Christina was thinking when she decided to leave. I would have already passed out on somebody's sofa at 4am just from drinks, so what drugs were they doing? Did the girls left at the apartment make her uncomfortable in some way? Brought up the past or something? So scary out there (and I lived thru the 70s heydays!). I also think the shed is going to be significant in some way. His clothes, her purse, drugs hidden? Sorry for all the questions!
