'The Jinx': Ex-Girlfriend Alleges Robert Durst Had a Creepy Extra Room with a Saw

If you haven't watched HBO's amazing documentary "The Jinx," watch out: spoilers follow.

Whether you watch the show or not, chances are you've heard by now about the startling ending that had Robert Durst seemingly confessing to the murders he's been accused of while muttering to himself off-camera. Durst was arrested the same night as the finale, and will now stand trial for the murder of Susan Berman.

Now that Durst's story is in the public eye again, stories about the man are starting to come out of the woodwork. The latest is an allegation from an ex-girlfriend of Durst's that claims he had a separate room in his apartment with a concrete floor...where he kept only a saw.

According to sources who spoke to the building's manager, Durst apparently wanted the extra room because he "used a lot of chemicals."

All we can say is that it's a good call on the part of the judge in his current case that Durst is being held without bail.
