Suspect in deputy deaths arrested in Utah in 2003 (Boston Herald)
Police in West Valley City, Utah, said they took a fingerprint from a man using the name Marcelo Marquez during a misdemeanor hit-and-run arrest in 2003. Court records show that he pleaded guilty, received a year of probation and was fined about $500.
However, Utah authorities never connected him to his real name or his previous criminal record.
In Utah, fingerprint data is entered into a biometric database for all people booked into jail. But for those who are cited and released, police take a print from a single finger that’s kept in state criminal records.
Unless there’s a request from an investigator, the print is not run against the biometric database to determine whether the person has a prior record outside Utah or is using an alias, said Alice Moffat, director of the Bureau of Criminal Identification.
Biometrics are a great way to root out criminal aliases, but only if procedures are in place to run the biometric search.
