SHAWNEE, Kan. (AP) — Suburban Kansas City police say they are looking for possible links between a botched gun shop robbery and other thefts in the area.

Shawnee Police Department spokesman Maj. Dan Tennis said “a ton of information” was coming in after 44-year-old Jon Bieker was fatally wounded Friday. Bieker was an owner of She’s a Pistol, which caters to female gun owners.

Two suspects were transported from the store in critical condition. Police said that the other two suspects, including one who suffered less serious wounds, fled but were located a short time later on the porch of a nearby home.

The Kansas City Star reports that jail booking records show all four suspects are Missouri teenagers. Two of the suspects previously had been accused of weapons-related crimes in Kansas City.
