Are we supposed to believe that... (SPOILERS)
There wasn't ANY evidence that could incriminate Lila? She wasn't super careful or trying to cover any trace. They could have easily found fingerprints on Alonzo's girlfriend house, a door handle or something.
And I know the police didn't found any evidence but how could she have gotten away with all those murders just because she had alibis from the women of the group even if it was so damn obvious that she did everything/confessed to the detective?
