FBI re-checking its fingerpint database

WASHINGTON – The FBI is checking its computer database containing the fingerprints of roughly 45 million people to make sure it’s working properly, following the bureau’s admission that it missed a fingerprint match for a man who authorities say later killed four women.

The FBI says its Integrated Automated Fingerprint Identification System did not experience a systemic breakdown when it failed to match the prints of a man arrested on a trespassing charge in Georgia in 2004 with those already on file belonging to someone wanted since 2000 for sexual assault in Oklahoma.

Jeremy Brian Jones has been charged with three murders committed after his release and police say he confessed to a fourth.

“It doesn’t make every match. It never has and it never will,” said FBI spokesman Joe Parris. “Obviously, the fact that the system didn’t pick up this match had tragic consequences. We don’t deny that.”

Still, the incident is under review and the FBI is checking the system with a focus on fugitives, he said.

“Once people are entered into the system as fugitives, we’re taking the prints and running them back through the system to ensure that the system will make the match,” Parris said.

FBI officials have called the system, in use since 1999, a big improvement over manual identification, which took 15 days or more and was less accurate.

The current system usually produces results in two hours.

Even when functioning well, the fingerprint system is 95 percent to 98 percent accurate as it pores over 50,000 prints a day, Parris said. The system contains 450 million individual prints, which equates to roughly 45 million people.

That accuracy rate would translate into many mistakes each day, given the high volume of fingerprint searches, said Simon Cole, a criminology professor at University of California at Irvine who specializes in fingerprints.
