State police use high tech link to solve murders

BATON ROUGE, LA (WAFB) -

Agencies across South Louisiana are training agents on a high tech link that helps solve crime faster in and around Baton Rouge.

The state police crime lab is one of the first agencies to get the upgraded technology known as the National Integrated Ballistic Information Network.

The system is housed at the State Police crime lab, but belongs to the federal government. It's commonly called: NIBIN. The network uses high tech tools to match parts of bullets left behind after someone uses a gun to commit a crime.

"In a lot of cases the detective may not have a lead or any kind of information that's going to help him solve his case," said Jeff Goudeau the firearms supervisor for Louisiana State Police Crime Lab.

"We can tell him, ‘hey the gun that did your shooting is the same as the one in another shooting' which can sometimes be in a whole different agency or at least a different part of the city," Goudeau said.

Crime lab officials say they've linked 600 shootings to each other so far. Sometimes a single gun has been used at many different scenes- in one case, at least eight different scenes.

The system works when a gun is used and evidence is collected which is then entered into the system. The markings on the bullet may match others already in the computerized system.

"The technology only helps provide us with leads," Goudeau said.

"The technology helps us say, 'hey these two cartridge cases look like they may have been used in the same gun.' We still have to manually put it on the microscope and confirm and it has to be two examiners to confirm that it is the same gun that was used in those two scenes."

Depending on the crime, and urgency of the matter, the system can provide real time results and even with normal cases the results can be much faster than before.

"We still can't do things in an hour like they do on TV, but from the time a shooting occurs normally we can have a report in a detectives hand within two to three weeks," Goudeau said.
