An Alaska man was sentenced to prison Wednesday after a national ballistics database linked him to five separate shootings in Anchorage last year. The 41-year-old has a criminal history in at least three states.

Christopher Kofi Noble of Anchorage was sentenced to serve 10 years in federal prison for being a felon in possession of ammunition, a release from the U.S. Attorney for Alaska's office said Thursday.

Noble was connected to five different 2018 shootings in Anchorage, all of which occurred during a three-month timespan. The Anchorage Police Department used the National Integrated Ballistic Information Network to connect the shell casings from the shootings to the same firearm.

"The NIBIN system is a database that catalogues shell casings found at crime scenes and makes comparisons to other shell casings at other crime scenes," the release states. "It allows the Anchorage Police to compare shell casings and determine if the same firearm was used on different occasions during different shootings."

Noble was connected to the following shootings:

•     April 3, 2018: A shooting where police say he shot at a woman who owed him money.

•     April 18, 2018:  A shooting where he shot at an apartment building.

•     May 18, 2018: A report of gunshots near the Sullivan Arena.

•     May 30, 2018: A shooting where he shot at a man he was arguing with.

•     June 14, 2018: A shooting where he handed a firearm to a man who shot and killed someone.

According to the release, .45 caliber shell casings were found at each scene. Those shell casings were all traced back to being shot from the same firearm.

“NIBIN has proven to be an invaluable tool in the fight against crime,” said APD Captain Josh Nolder, Commander of the Detective Division. “Thanks to NIBIN, we can now link seemingly random cases to one firearm and bring the individual behind that firearm to justice.”

Noble has five priory felony convictions out of Illinois, Indiana and Alaska for crimes ranging from assault to eluding law enforcement and possession of cocaine. As a felon, he was prohibited from having firearms or ammunition.

“ATF is committed to working with our partners across the state to protect Alaskans from violent offenders like Mr. Noble, whose contempt for law and order led to his continued criminal use of firearms, placing the community at risk,” said Bureau of Alcohol, Tobacco, Firearms and Explosives Seattle Field Division Special Agent in Charge Darek Pleasants. “Sentences like this one serve as a deterrent to others while removing a repeat violent offender from our streets.”

At Noble's sentencing hearing, Chief U.S. District Judge Timothy Burgess said Noble has 28 prior criminal convictions and over 29 other arrests. Noble was given the maximum sentence for his crime, after Burgess said he was concerned about Noble's "history of violent and assaultive behavior" and protecting the public.

APD and ATF investigated the case against Noble, which was prosecuted by Assistant U.S. Attorney Kelly Cavanaugh.
