didn't the DNA test come back as belonging to YY? My concern though, is that if he simply manhandled YY in the room and then picked up the bat he could transfer her DNA to it -- doesn't mean he ever hit her with it... I mean how do you bash someone in the skull with a bat and be assured no neighbor will hear it (apt. walls are usually a tad thin); or what if you miss a little and hit the wall or plumbing fixtures; just doesn't seem a likely action to take; so many quieter ways to kill, with all the knives available or smothering or drowning in tub. There is a memorable scene in "American Psycho," however, of a victim being bashed in head with a hatchet as I recall.
