Algo le pasa a la tía Diane

There's a fatal traffic accident that left aunt Diane, her daughter, 3 nieces and 3 men in the other car dead. The case is revealed slowly. In fact, it's done too slowly. What went wrong? After watching so many police procedurals, it's obviously that we need the tox report but they keep holding it off. Instead, they keep going to family and friends who repeat the same sentiment. She's a great mom, and they have no idea what happened. Once we really get into it. It is a fascinating story. The family starts giving more insights. The story gets moving. However in the end, we don't really get the whole story. The movie could be a simple hour-long investigative piece that ties in with the larger drug epidemic. It's not necessary to drag this out so much.
