something i dont understand
what happened between the father at the start of the movie and the killer. when the cops were watching the killers interview and realised who he was, they went through all the victims and said wot happened. but with the father from the start, i think they said "thats when it really went bad."
but they didnt say wot happened. im halfway through the film so unless it explains at the end, then i have no clue wot went down between them.
