yes but the way she was both murdered and disposed of doesn't suggest he had known her or even known of her, she was strangled with her guard case this suggest a sexual sadist, and or power orientated. Since her garments were tapered with I am personally leaning more to sexual sadist. For the fact that he used the guard case suggest that he didn't have a personal relationship with her, because if he did he would have wanted her death to be more intimate and would have used his hands. The fact that he dumped her body in an open area suggest hes not a native of the town. If he was he would have disposed of her body in a more discreet place for fear of it leading back to him.
