I had heard about this case several years ago but just read the WS thread on it this morning. My questions are about these two vehicles seen in the area:
A dark-colored van or minivan was parked at Caldwell Fields after dark.
A gray or cream-colored early 2000s model Pontiac Bonneville, parked near Caldwell Fields around midnight.

Is the only place to park near Caldwell Fields the parking area where the murder was committed? If so, I don't see how either of these vehicles could be parked there at the times listed and not see something either happening or the aftermath of the crime/Heidi's body on the ground. I have seen photos of this parking area and it seems pretty small, not like a huge parking lot. If they were murdered around 8:30/8:40 PM, I could maybe see the first van arriving before they showed up (all it says is "after dark," and with sunset being at 7:57 PM that day according to Google, I guess it's possible they were there closer to, say 815, but whoever witnessed the van said it was "after dark"). But the midnight vehicle--with headlights on, wouldn't it illuminate the crime scene in that small parking area?
Now obviously, that would be if the vehicle's occupant was innocent. But if it was the killer, it would be kind of stupid to return to the murder scene a few hours later. I wonder who gave police descriptions of these vehicles? I thought the closest houses were about a mile away? So does that mean the witness/witnesses of these cars were also other people out driving around near Caldwell Fields that night? I'm assuming more than one as these sightings span the course of a few hours. If so, within the span of only a few hours when it is pitch dark out, that's quite a few cars in that very remote area! Possibly 12 if there is a separate witness for each of these vehicles in question.
