It's about a pair of brothers who are serial killers. They are middle aged or young adults.
They live in a house, in a woody area. The older and bigger brother takes the victims home, kills them, chops them up and the younger brother does the cleaning. The younger brother was slightly retarded and had a speech impediment. His name was something like Toby or Doby.
For some reason the older brother doesn't kill a woman he took home, but instead forces her to be a part of the cleanup crew, alongside his younger brother.
