I read somewhere that the neighbor, Mrs. Medina, was up early on Dec. 24 and looked out her window and happened to see Scott's truck in the driveway at just about 5:00 a.m.
Now, we're postulating that Scott did Laci in after 8:30 p.m. on Dec. 23, right? So now I'm estimating a window of time for all Scott's body disposal activity--a window between about 8:40 p.m. and 5:00 a.m. Still very possible, still plenty of time, but the time has been shortened up a bit, hasn't it?
