The killer fisherman is the father of the girl Susie. He killed the boy who they thought they'd ran over, then the kids ran him over. Barry is killed and so is Helen along with Elsa, Max and some police guy escorting Helen home from the pagent. Ray was Billy Blue, but he just wanted to see Missy so he used the name of his boat. The killer takes off in a boat with Julie but as he's about to kill her Ray cuts the guys hand off and he falls in the water. A year later Julie is in a shower when she sees "I still know" written on the wall. The fisherman then bursts through the glass. We don't find out Julie's fate until the sequel.
