A system upgrade through the bureau of Alcohol, Tobacco, Firearms and Explosives is helping local law enforcement solve gun crimes in Memphis with forensic ballistics.
“We match bullet casings and cartridges found at crime scenes and match them to firearms,” said TBI Forensic Scientist Supervisor Shelly Betts.
ATF numbers show that in 2012 more than 2,400 of the 6,300 guns recovered and traced in the state of Tennessee were recovered from crime scenes in Memphis.
The guns themselves are traced back to the manufacturer and retailer through the ATF’s e-Trace system.
Those crime scene guns are tested at TBI headquarters in Nashville, where forensic experts collect the bullets and shells and then compare them to the bullets and shell casings collected at the crime scene.
A camera zooms in on the casings and shows large images on computer screen for comparing purposes.
