A maintenance worker inspecting a northeast Minneapolis apartment made a startling discovery last fall: a duffel bag full of guns stashed in a closet.
Police think the recovered handguns are linked to the theft of more than 30 firearms from a pawnshop in northern Wisconsin last year, a case that has piqued the interest of federal law enforcement agents, but remains unsolved.
The firearms were among the more than 700 handguns, shotguns, rifles and other semiautomatic weapons seized by police around the city last year, thanks to what authorities are calling a combination of old-fashioned police work and modern technology.
If the current pace of gun recoveries keeps up — 258 guns in the first four months of 2019 — police will top that total by the end of this year. Still, gun recoveries are down nearly a third over the past decade.
Minneapolis Police Commander Jason Case said police investigating gun crimes are making greater use of high-tech DNA analysis and forensic science, such as the National Integrated Ballistic Information Network at the federal Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), which lets investigators tap into a national database of weapons evidence that can help link firearms to crimes.
"I think our goal is always to use our analytics and our forensic evidence to always drive what we do," said Case, who heads the police division that includes the homicide, robbery and weapons units.
He said authorities are also concentrating their efforts on the relatively small number of individuals and locations that drive most of the violence in the city.
Data released by the department through an open-records request shows that roughly 40% of the 704 firearms recovered last year were seized in drug-related cases. Another 112 guns were recovered in connection with a homicide, robbery or serious assault. Sometimes, it's during a traffic stop, like earlier this year when officers pulling over a vehicle discovered a black Colt .22-caliber semiautomatic rifle, with an obliterated serial number and the word "killer" carved into its side. That firearm, like many others seized by police, appeared to have been obtained illegally.
