Authorities found nearly 150 grams of marijuana and a revolver in millionaire Robert Durst's hotel room when he was arrested over the weekend, a prosecutor said Tuesday.
Durst appeared before a judge for a second straight day to face the drug and weapons charges. He also is charged with murder in a Los Angeles killing 15 years ago.
He has been suspected in the disappearance of his first wife and he won an acquittal on a murder charge in Texas.
In a documentary about Durst's troubled life, he mumbled about how he "killed them all," providing a dramatic kick to the end of the series. But a law enforcement official said his arrest on the murder charge was based on words he wrote.
Analysis linking a letter Durst wrote to his friend Susan Berman a year before her killing with one he said "only the killer could have written" to point police to her body was the key new evidence in the long-dormant investigation into the 2000 killing, the official not authorized to speak publicly told The Associated Press on the condition of anonymity because the investigation was ongoing.
Durst, 71, was charged Monday in Los Angeles with first-degree murder in the shooting of Berman, the daughter of a prominent Las Vegas mobster. He could face the death penalty under special circumstances that allege he ambushed her and murdered a witness to a crime.
He waived extradition in New Orleans, but authorities there charged him late Monday with being a felon in possession of a gun because he had a revolver when he was arrested there Saturday. Assistant District Mark Burton said they found the pot and gun in his hotel room.
