His stories from the beginning: * I dropped her off at the dock * She died, I buried her at sea * She died after a hatch fell on her head that I was holding up, but was too heavy; I dumped her body in the sea, but I did not dismember her * She died from CO poisoning, I dismembered her and I dumped her body in the sea At this point, he's a single step away in his story from admitting to the murder. After that there's one more step from admitting sexual assault (which the 14 stabs to the pubic area seem to suggest).
