Denver, Colorado 2021-07-17 11:29:08 –

Pueblo — Shots are fired. The suspect is not immediately identified. However, if one shell casing is found, police are more likely to resolve the crime.

For example, consider the 2017 murder in Pueblo. In this particular case, investigators rarely continued, with the exception of the four shell casings where the bodies were found and recovered at the scene. Originally, those casings National Integrated Ballistic Information Network (NIBIN)..

NIBIN is a database containing 2D and 3D images of cartridge case launches collected from crime scenes and photos of shell casings submitted by law enforcement officers testing guns collected as evidence. As more local law enforcement agencies join NIBIN, more images of shell casings will be submitted, increasing the likelihood of finding a match for a particular crime. Detective Greg Egan of the Pueblo Police Station said, “Regaining the results of the shell casing reveals that the gun was used in another scene. This may allow us to continue something we have never seen before. Maybe. ” He is also a Task Force Officer of the Bureau of Alcohol, Tobacco and Firearms (ATF).

“Each gun is located in a place like a thumbprint or fingerprint. There are no two guns in the same way.”

Detective Eagan said the ATF spearheaded NIBIN in 1999, but in 2015 the system was promoted nationwide.

Detective Egan had News5 see behind the scenes how a gun was test-fired at the Pueblo police station. The shell casing is then sent to the Colorado Research Office (CBI) in Pueblo, where it is entered into NIBIN. “For the caliber you enter, it’s usually 9mm or 40mm, but about 50-100 images are returned and need to be checked. Check the top 50 for potential law enforcement leads. I’m a partner. ” Janel Lions, a CBI Pueblo laboratory engineer, said.

Data collected by the Pueblo Police Department show the density of drive-bys, shootings, and shootings fired between January and May 2021.

In the 2017 Pueblo murder, the cartridge cases found did not immediately ignite Reed, but murder investigators were able to identify the person of interest after months of investigation. The person of interest was arrested after being contacted by Colorado Springs police. A 9mm pistol was found in the car during his arrest and was confirmed through NIBIN as a murder weapon used in Pueblo a few months ago. A person interested in the murder became a suspect and was found guilty of the second murder. They were sentenced to 47 years in prison.

Detective Egan said the conclusion of the case was the result of both Pueblo and Colorado Springs police believing in NIBIN. “You got the right part in place, the next part in place, and you’ve ruled 47 years from almost nothing. That’s the volume … NIBIN is there. Would we have been there if we weren’t there? “Eagan said.
