Thanks anniem15.
http://www.trutv.com/library/crime/criminal_mind/forensics/imbo_petrone/1.html had some good info. Everyone reading this should check it out. It settles the issue of where Danielle's car was. This is significant I believe.
I have always believed that the Truck disappearing with the victims is consistant with a driving mishap and not consistant with a double murder. Apparently I am not alone in my suspicions. As I have learned more, I feel stronger about this. A double abduction/murder that night seems unlikey. My reasoning is as follows:
Danielle went into Philly with Richards mother. She had no plans to go anywhere with Richard; that came up at pretty much at the last minute. How would any "hit man" know where to find them? Someone suggested they followed them (all evening through the streets of Philly?) If they did, where would they do the deed? Not near State St. Valenitine said there were lots of people on the street. A friend of mine, from the area has confirmed that there would be crowds on the street Saturday night a midnight. Crimes can and do happen but a "hit man" would not select such a spot. The same would apply to anywhere between there and Mt Laurel. These are city or suburban streets. There would be plenty of cars around and cops, cruising for DUI's, would take notice of any accident, "staged" or not.
Danielle'd condo is a possible abduction site. Everything I've read suggests that LE believes it occured "on the way back to Mt Laurel", not at the condo. Since the initial focus of the investigation was seaching waterways and other possible "mishap" sites, I going to assume that nothing was found at the condo to indicate that it was a crime scene. Nothing of interest in the condo; nobody saw or heard anything etc. We now know Danielle left her car there. It wouldn't take a criminal genius to figure out she was probably with some guy. They wouldn't know who she was with, when she would get in or even IF she were coming back at all. Who would sit in their car for hours where any neighbor might take notice? Finally, I found he condo (Brittany Commons) on Google Earth. The "row house" type condo has no attached garage. Parking is perpendicular to the driveway with no roof or any other shelter. Anything unusual like an abduction or carrying two bodies fron the condo to a car would have to be done out in the open. Not an ideal spot.
Some have suggested that the "ex", a middle class mortgage broker with no criminal record would have the where-with-all to retain a Mafia type profissional "hit man" who would be able to pull this caper off inspite of the problems. I find this most improbable of all.
I think we, and LE (assuming they don't know something earth-shattering we don't) need to reopen the possibility of a vehicular mishap.
