New Mexico DOJ data: Shell-casing tracking links shootings in Doña Ana County

LAS CRUCES, N.M (KFOX14/CBS4) — A gun-tracking program that uses shell casings to connect shootings is already helping investigators link crimes in Doña Ana County, according to new numbers released by the New Mexico Department of Justice.

The effort is part of New Mexico’s Crime Gun Intelligence Center, which uses ballistic evidence such as shell casings to track guns believed to be used in multiple crimes. The program relies on the National Integrated Ballistic Information Network, or NIBIN, a national database that compares ballistic evidence to determine whether shell casings may have come from the same weapon.

In April, New Mexico Attorney General Raúl Torrez described how the technology can connect cases across jurisdictions.

“There may be a shooting that occurs in Deming that’s actually connected to a crime gun that’s recovered in Las Cruces. We may find shell casings in Silver City that are connected to something that happened in T or C,” Torrez said.

Four months into the program, the Department of Justice said 210 bullet casings have been analyzed in Doña Ana County. Those casings helped link 32 incidents to 13 guns.

Statewide, more than 700 casings have been entered into the system, connecting 74 shootings to 31 guns.

One person reacting to the numbers said, “That’s crazy. Honestly, all those shootings all coming from that little amount of weapons is crazy.”

New Mexico officials say the system is designed to help law enforcement share information faster and build cases more efficiently.

Also in April, Doña Ana County Sheriff Kim Stewart pointed to a local case she said the technology helped resolve quickly.

“We resolved a homicide with a suspect arrest in four days. We know that those casings may lead to another 1 or 2 incidents in another city,” Stewart said.

Some residents said the technology alone will not solve gun violence, but they see it as a step forward. One person said, “I mean, growing up, like hearing gunshots in the distance. That wasn’t something crazy. I have stories of, like, friends who’ve gone to parties that had guns go off there. So, yeah, I would say guns are a problem there.”

Another person said, “I would think that it’s a good thing. I’m personally like, just anything to help the gun crimes, you know?”

KFOX14/CBS4 contacted Las Cruces police and the Doña Ana County Sheriff’s Office to ask how the leads are being used in local investigations, but we are awaiting a response.
