He shoplifts a sandwich because HE DOESN'T FEEL LIKE PAYING FOR IT???

There was nothing that Berman knew about the mob that would make her a target for them. She was the daughter of an associate of Bugsy Seigel. She's an outsider, nothing more. Durst killed her because the district attorney was In the process of reopening the case and he didn't want her talking to anyone.

Touch darkness and darkness touches you back.

This guy doesn't live in the reality that the rest of us live in. He has created a different one for him self.

A Philosophy professor I many years ago told us about the Professor he worked closely when he was in grad school as a TA. The guy had sort of adopted the personality of his specialized field. This guy was walking around in a school of higher learning suffering under the delusion of Solipsism. He thought the entire would and all of existence was his dream once he slept or even left the room it stopped happening. He had a team of grad students that supported this delusion because well he was on the board for the dissertation and also they where his teaching his classes.

Just like Mr. Durst this long dead Philosophy professor had a mistaken view of the world. They both have a support system who have the means and motive to uphold those beliefs. Dursts' family don't want to have there son who is by his words "jinxed' put away for deviant behavior. Just like the grad students in my story don't want the crazy Prof they can manage get upset and they PhD hopes to be ruined.

Tl;Dr- Some times people are crazy, sometimes people help crazy people maybe they are the luckiest people in the world?

Shut it down

The Berman lady could of been killed by Bobby or by the mob. She was writing a documentary about the mob dealings in Vegas and naming people that didnt wanna be named in that documentary. She could of easily been wacked by the mob just as easily as been wacked by Bobby to shut her up.

That one can stay unsolved as far as I'm concerned...

Maybe he has shop lifted before, but this is the first time he got caught.

Nope, he killed her. Why would the mob send the cops such a letter after a hit. And the icing? Did it in the same style writing as Durst.
Now Durst does say in the series, in a mocking kind of manner, oh yeah someone spelled Beverly wrong and then when confronted at the end of episode 5, he was shown a letter he had written to Berman with the office address he had in New York. So he verified it, then shown the letter he had written to Beran with the same return address, and her address with the same misspelling and very similar block style lettering in the same handwriting he was visible taken aback. He couldn't explain it, the same misspelling and he had nothing to say except I can see how they would think I wrote it. He kept hammering on the block style lettering because in some books about how to get away with a crime, some forensic show I saw, the perp used a forensic handwriting book and one of the things was using block style lettering to make it difficult to discern who wrote it. However, it is apparent this guy did a poor job and you can see, I mean Ray Charles can see, the handwriting is very similar if not the same.

His face told it all. He knew the jig was up. He wasn't expecting to be confronted with evidence.

My girlfriend, who is getting her Masters in social work and is studying mental disorders, says he has classic symptoms of Dissociative Identity Disorder aka Multiple Personality Disorder. A couple examples being talking to himself and referring to himself as "we" or in the third person from time to time. It is very possible that one part of Durst wanted to get away with his crimes while having another part who actually felt guilty and wanted to be caught. You could even say his request for doing an interview was a sign of this since it was against the advice of his lawyers. Also, the cadaver letter.
