Just get over it, and develop theories that take it into account. Why are people so certain Danielle died so soon?
The very theories according to which she died SOON, are also the ones that put her parents and their minions in a position to have refigerated or sealed away the body inside out of reach of flies.
Because it's unusual to not get rid of the body quickly..the longer the perp keeps the victim, the chances of him getting caught increases....
