It's the ever evolving motive. If the first one doesn't make sense or is proven to be incorrect, then move on to the next. That one also is shot down? Then go on to the next one in line. Repeat this for a few more motives. Finally Amanda admits to playing a prank with help on someone. Nothing was stolen, nothing was broken, no one was killed or injured BUT it doesn't matter. We finally have a motive that "fits". Never mind the fact that the one that killed Meredith has a history of breaking and entering, using knives, tried to attack someone when his exit was blocked and was a problem with/for women. That person that had his DNA, fingerprints, footprints at the scene of the crime was just an innocent bystander in the crime. Even though he lied about why he was there that night, smearing Meredith's name and reputation in the process.
Of course the "prank gone bad" motive works. It just doesn't make any sense that a breaking and entering went bad. Nope, not at all.
