im a huge fan of horror, and die hard fan of Scream. however when i watched scream 3 i noticed the killer left the pic which read I killed her. now if im not mistaken, billy and stu killed maureen (sids mom). so when we discover its roman, he mentions that he gave billy the motivation to kill maureen. now here is my question the line "I killed her" does that mean that roman was the one that physically killed her? or does that mean that he is responsible for setting the whole thing up (filming her with billy's dad, giving billy motivation)? i understood the part about him being an unwanted child and that he was "rena's" child. but i just never understood if HE really killed her or just put the whole idea in motion for billy.
