Second Circuit OKs Use of Now-Defunct DNA Testing Method

In United States v. Jones, the Second Circuit (Kearse, Cabranes, Sack) considered the admissibility of DNA evidence based on the “Forensic Statistical Tool” method (“FST”), which was previously utilized exclusively by New York City’s Office of the Chief Medical Examiner (“OCME”), but has since been abandoned because it does not meet the requirements of the FBI’s national DNA database.  One presumes that the mode of analysis used by the Circuit will be used by district courts to analyze the new methods of DNA analysis, meaning that the case will outlive the specific facts presented.


Second Circuit Rejects Coin Dealer’s Coram Nobis Petition

Robert du Purton was convicted of mail fraud and conspiracy to commit mail and wire fraud in 2001 for participating in an “elaborate scheme of fraudulent representations” in his rare coin business.  According to trial evidence, du Purton lied to customers about the sources of coins, concocted phony auctions to drive up prices, and had his employees impersonate competitors or independent sources, among other things.  His conviction was affirmed on direct appeal.  Nearly fifteen years later, he brought a petition for writ of error coram nobis, claiming that the government presented false expert testimony at trial.  In a per curiam decision, the Second Circuit (Katzman, Leval, Andrew Carter, District Judge) affirmed the denial of the petition.
