I dont know the motive for this, Det. Sgt. Matt Kavanagh said Thursday.

I believe what the police have said is that the truck was a target not that it was the motivation for the crime. The idea that this was "all for a truck" makes a neat soundbite, but it doesn't actually explain motivation as the next obvious questions are "Who on earth would do such a thing for a truck and why?"
Is anyone actually thinking, "Yep, the truck's the motive. That makes perfect sense."
Archangel7 points out above why a broken engagement is indeed relevant. I think police would be negligent if they didn't attempt to to question the ex-fiancee and just said, "No need to talk to her. They did it for the truck, after all."
Thanks everyone for the welcome.
