@Manzambi Pedro, in response to your comment: at the end of the movie when Shia’s character goes into the neighbours house he goes to the vent. Open its and sees the red haired girl inside. Then when Shia goes into a room further down the house he comes across a red wig. (Which implies the neighbour put it on and drove the red haired car away to make it look like it was her) did you even pay attention to the movie?
