What is worse is he was on parole and it is reported the parole officer checked up on him. I guess they never talked to the neighbors or went into the back yard.
In the presser, the Sherriff said that the girls were kept in a screened-off portion of the yard. He said it was really quite unusual, but you could visit the house and go into the back yard without realizing that this area was even there. Couldn't be seen from the neighbors either.
Really odd.
