Here's what the trip would've looked like that night on Google Maps.
goo.gl
1 - hotel that she was staying at or walking to
2 - this is his apartment at the time - Sunset Lodge. I don't think they stopped here but just a reference point that they would have literally drove by his apartment if in fact, they did make it as far as the boat launch.
3 - Pole Yard Way location that has been referenced throughout the case
4 - the spot shown at :08 in the video is the last spot I have on the trip which is the area that they recovered her body.
