1. Where didn't the girl come from?
2. No...the woman did have a child.
3. The girl was compelled to kill because of mistreatment by her father.
4. After the girl got out of the mental hospital, apparently.
5. I dunno...It's a movie.
6. The video was made to tell her story, not to rescue the corpse. How? Again, it's a movie.
7. Damn kids...
8. The child was killed and mother committed suicide after both were released from the hospital.
Pretty well made movie, in my opinion. Made your blood run cold...
