If he went out for food at 12:50 and returned at 1:34...they chowed and then went for a walk?? Usually one gets logey(sp) right after eating. Did Howard encourage the walk? Whoops...both other witnesses are dead.
I think it lends more credence to his being absent from the hospital from about 2 am to 4 am.
I doubt Daniel and Anna were that quiet leaving and entering the room for Howard to claim he was asleep during their walk. Didn't Anna have her I.V. still in her hand at the time? Wouldn't she have been pulling around an I.V. stand? I don't know how long women have I.V.'s after a C section. I never had one.
