Robert Durst had three crime-related books inside his Houston apartment when it was searched by police on Tuesday, according to authorities.
A book, titled "Without a Trace," and two copies of another tome, "A Deadly Secret," which details the search for Durst's first wife who went missing in 1982, were found in the 71-year-old's Houston apartment, according to a list of the items recovered in the execution of a search warrant, police said.
The search warrant does not list the authors of the books in question, but there are books with those titles that focus on the disappearance and search for Kathie Durst, who went missing in 1982 and was declared dead in 2001 even though her body was never found.
Court records detail how the accused murderer had seven credit cards, seven blank checks and five boxes containing court documents and news articles in his possession. He also had a trash bag filled with court transcripts.
The subject of the court transcripts were not specified.
Durst was arrested on Sunday in New Orleans and charged for the 2000 murder of his friend Susan Berman, who was found dead in her apartment in Los Angeles.
Durst is now being held at a mental health facility in Louisiana after sheriff's office officials expressed concern that he could be a suicide risk.
Durst was previously acquitted of killing his neighbor Morris Black in Galveston, Texas in 2001, after saying that he shot Black in self-defense before dismembering his body and dumping the parts in garbage bags in Galveston Bay.
Durst’s lawyers have maintained that he did not kill Berman and have said that they want him extradited to California to face trial, though he may now face additional charges in Louisiana because he was allegedly found in possession of a weapon and marijuana when he was recently arrested.
