Robert Durst, who was the focus of HBO's documentary The Jinx, was attempting to change his identity at the time of his arrest on Sunday.

According to the search warrant obtained by TMZ, Durst was found in possession of a latex mask which, when worn over his head and neck, completely changed the appearance of his face. Law enforcement also discovered a fake Texas ID with the name Everette Ward in his New Orleans hotel room.

Durst was seemingly planning to use the mask and ID to flee the country. He had over $42,000 in hundred dollar bills divided into small envelopes, which the police believe he planned on sending to his ultimate destination. However, the warrant states that Durst was planning to mail much more than $42,000. According to his bank records, Durst withdrew $9,000 a day for 35 consecutive days, adding up to a total $315,000. (Durst is reportedly worth more than $100 million.) Officers also discovered a UPS tracking number in Durst's room, which he admitted was to ship a large sum of cash.

In addition to the cash, a .38 Smith & Wesson revolver with one spent shell casing and four live rounds was found on the scene, along with both a paperback and hardcover copy of of A Deadly Secret: The Strange Disappearance of Kathie Durst, which is about the presumed murder of his wife.

Durst was charged with first-degree murder on Monday for the death of his friend Susan Berman. The Los Angeles police reopened the investigation into Berman's 2000 death as a result of The Jinx. He is also the person of interest in the disappearance of Kathie Durst and the murder of his neighbor Morris Black.
