<text>  A failure in LAPD handwriting analysis 14 years ago meant that Robert Durst was free to kill again, according to a search warrant. Durst, a member of a wealthy New York real estate family, was arrested in New Orleans over the weekend and charged with murder for the shooting of Susan Berman in December 2000. Police focused on Dursts handwriting 14 years ago, after a note in an envelope tipped them off to Bermans death. But a document examiner wrongly concluded that the handwriting did not match Dursts. Scroll down for video . Accused: Robert Durst was arrested after he seemed to give himself away during a taped interview for an HBO documentary investigating his possible links to three killings . Evidence: The handwriting on this notorious note that tipped off police was eventually matched to Durst . Missed: The handwriting was initially thought to belong to somebody else after LAPD analysts made errors in their assessment . Match: Eventually, the writing was compared against samples of Dursts writing and the similarities were found to be striking . Sinister: Robert Durst is escorted into Orleans Parish Prison after his arrest. He escaped police attention for years, partially due to a failed handwriting analysis 14 years ago . Writing on the note and envelope, which was written in block lettering, misspelled Beverley Hills Police and included the word cadaver along with Bermans Beverly Hills address. In 2001, Los Angeles Police Department document examiner William Leaver concluded it was highly probable that it was written by Nyle Brenner, Bermans manager and friend. The assessment was rubber stamped by Leavers supervisor, who told detectives in September that she had not backed the findings up with an independent technical review. Investigators had initially failed to analyze examples of Dursts handwriting, and it wasnt until eight months later that a comparison was made. Leaver said similarities were enough to request more writing samples, which police eventually obtained. In June 2003, Leaver revised his assessment to conclude that the handwriting was likely Dursts. The conflicting analyses meant that valuable time lost. By then, Durst had been charged in Texas with the murder and dismemberment of Morris Black. Investigation: Law enforcement officers stand outside the Robert Dursts Houston home . Forensic: Durst himself may have implicated the property in a recording made while talking to himself after a tense interview for the HBO series . Eventually, the envelope, letter and writing samples were sent to the California Department of Justice and an investigator concluded that Durst was probably the author of the cadaver letter and note. The Los Angeles case went dormant, and wasnt revived until 2012, when law enforcement learned of a six-part HBO series about his links to three killings entitled The Jinx: The Life and Deaths of Robert Durst. He is suspected of killing his first wife, who disappeared in New York in 1982; Berman, the daughter of a mobster, who acted as his spokeswoman after his wife disappeared; and a 71-year-old neighbor in Texas, whose dismembered body was found floating in Galveston Bay in 2001. The filmmakers say they shared tape with police months ago of interviews with Durst, including his reactions to handwriting analysis and what appears to be a confession to Bermans killing. In October and November, the LAPD had two independent examiners analyzed the documents and both concluded that Durst was the author. Durst was arrested earlier this month, shortly before the finale of the HBO documentary. He has only ever been tried for the Texas killing, and he was acquitted of murder. Authorities on Tuesday searched Dursts Houston home, and the warrant released Wednesday details the timeline of the Berman case. The LAPD has declined comment until Durst is in its custody. He is currently being held in Louisiana on gun charges. Dursts attorney, Dick DeGuerin, said the conflicting determinations on the handwriting shows you what junk science really is. He also questioned what evidence police expected to find in Dursts Houston home. But Durst himself may have implicated the property in a recording made while talking to himself after a tense interview for the HBO series, which concluded Sunday. Just before saying he killed them all, he says, I dont know whats in the house. The search warrant affidavit showed that authorities were concerned Durst, who has an estimated net worth of 100 million, might be preparing to flee the country. He had withdrawn large sums of money from multiple bank accounts, including daily amounts of 9,000, for 35 days starting in October. Durst was under FBI surveillance. Agents arrested him in a New Orleans hotel under the name Everette Ward, finding nearly 43,000 in cash, a gun and a rubber mask that could cover his head and neck in his room, the affidavit says. A law enforcement official with knowledge of the investigation said that it was a kind of old man mask, and investigators were looking at whether he had been using it to travel anonymously. Durst could face the death penalty if convicted of killing Berman.
