The truck = unlikely plot device

It's impossible that the truck would be left sitting on the street through an entire double homicide investigation. Obviously the vehicle was necessary to draw all the characters together sooner or later, but it really screams out as a screenwriter's handy invention. In reality, the house and surrounding neighbourhood would be crawling with investigators for at least a few days, and the truck would quickly be discovered NOT to belong to anyone in the neighbourhood, at which point it would be examined, impounded, examined some more, which would immediately trace it back not only to Anika, who owns it, but also to her lover Esther, whose prints were very clearly all over it. Yeah, I know, no movie without it, and frankly I do wonder if the writer/director could've come up with anything more logical to get his characters where they needed to be plotwise. With a two-plus hour run time, I suspect he could have, although it would've required a sizeable rewrite, I suspect.
