Robert Durst had a latex mask, a fake ID and $42,000 cash — mostly in $100 bills packed in small envelopes — in his room at the New Orleans hotel where he was arrested over the weekend, authorities revealed on Wednesday.
The disclosures came in an affidavit filed by Houston police on Tuesday — and made public Wednesday — as they sought a warrant to search Durst's home there.
Durst, an heir to one of New York City's most powerful real-estate empires, was arrested on Saturday and charged with the 2000 murder of his former spokeswoman, Susan Berman.
The arrest came a day before HBO, in the final episode of a six-part documentary on his life, aired audio of him on an open mic in the bathroom mumbling to himself: "What the hell did I do? Killed them all, of course."
Durst was also questioned but never charged in the 1982 disappearance of his wife, and he was acquitted on a self-defense claim after he killed and dismembered his neighbor in Texas.
According to the papers made public on Wednesday, the FBI estimated Durst's net worth at about $100 million at the time of his arrest. He had also begun withdrawing as much as $9,000 per day from his bank account beginning last fall, according to the FBI.
The search of his Houston home turned up bank statements, boxes of court transcripts and copies of three books — "Without a Trace" and both hardback and paperback copies of "A Deadly Secret." Both titles were about Durst.
