The Scarf...
Can someone explain...
At the end of the movie, the killer tries to strangle Jane with the red and black scarf.
But...
We already know that the police have the red and black scarf in their possession, because they found it on the body of an earlier victim and held it up as evidence when they were lecturing the students. So the killer would have to have bought another scarf.
Since the colour of the scarf has no special significance for the killer and he already knows that the police are looking for the person who wore the original red and black scarf, why would he go and buy an identical scarf?
Why not buy a green scarf and really confuse them. LOL
