hmmmm, but medical offices wouldn't be open in the middle of the night...but hey, i also think he did a LOT of driving...night & day, so it's possible, since he was out & about driving on that Friday.....
if he did this (& i think he did) he HAD to get blood on himself, IMO.....i'm guessing once he was 'done', he took whatever clothing he had on, off....(heck, maybe he put on some type of coveralls, prior to getting back to the house)....he would have had to be very careful about his shoes & blood, as far as footprints....(course he could have purchased some cheap shoes, prior to all of this).....see there i go speculating....i REALLY have to stop giving 'the perp' so much planning credit..... :doh:
