'The Jinx' Star Robert Durst Admits A Disturbing Drug Secret

New court documents have uncovered shocking details about Robert Durst and his secret drug past which he claimed "should have been obvious" to fans.

"I was on meth. The whole time I was on meth," Durst said during a jailhouse interview in March of 2015 in Los Angeles. The interview was finally filed on Dec. 16, where the star went on to admit even more.

"And, when I looked at the little pieces of it, I was going like this, and like that. And it was… it should have been obvious." To his surprise, Durst was shocked his lawyer continued to let him film the miniseries detailing his life because it "looked like there was something going on."

As RadarOnline.com reported, evidence continues to mount against Durst, who seemed to confess to killing a woman, Kathleen McCormack, (along with two other people) after being caught talking to himself on a live mic feed while filming The Jinx.

The 72-year-old is currently waiting for his trial in regards to killing Susan Berman in the 2000 murder case. So far, he's denied killing his late best friend.
