There are five endings you can get in the "Taxidermist" bonus
downloadable content. When you unlock one of the endings, it will be
marked off so you know which ones remain. Each of the ending's names
correspond to the newspaper headline shown once you have finished the
chronicle. You only have to replay the last chapter if you did not do
anything in the previous one to alert Leland of your presence.

In The Middle Of The Horror: Do not use the phone, and escape
without Leland following you outside. He can become alerted that
someone is in the house; just do not let him see you.
Sacrificed In The Name Of Truth: When the killer gets home, sneak
into the first bedroom, and call Sam from the phone on the side of
the bed. After the phone call, alert Leland, and let him kill you.
The End Of Anguish: Use the phone, and wait for the police to arrive.
The End Of The Nightmare: Do not use the phone, and escape with
Leland chasing you outside, or kill him with the chainsaw.
Where Is Madison Paige?: Do not use the phone, and let Madison die.
