More than two dozen knives were stolen from a car left unlocked Monday in Sioux Falls, prompting police to again warn residents against leaving valuables in unsecured vehicles.

At 11:27 a.m., the owner reported that six rifles, one shotgun and 24 folding knives had been stolen from display cases in a car parked near 46th Street and Palisade Lane, Sgt. Aaron Benson said.

There was no sign of forced entry to the car, leading police to believe it was likely left unlocked, Benson said. It's unclear why that many weapons were in the vehicle.

"This is another unfortunate case of another unlocked vehicle with stolen firearms," he said.

During the past few years, Sioux Falls has seen a rash of guns stolen from unlocked cars that then ended up being used in criminal activity. Sioux Falls City Councilor Pat Starr even proposed penalizing gun owners who did not lock up their guns in vehicles.

After eight guns were stolen from unlocked cars in less than a month last June, police shared their exasperation in dealing with the issue.

"We keep saying this over and over again," Officer Sam Clemens said last year. "People have to learn to lock their cars if they're going to leave guns in it."
