The Florida gun shop that sold the AR-15 assault weapon used to kill 17 people in a Parkland high school last week has shut its doors.

The owners of Sunrise Tactical Supply, the Coral Springs shop that authorities said in November sold suspected shooter Nikolas Cruz the AR-15, has been ‘‘closed indefinitely,’’ according to the Miami Herald. Cruz was arrested after the massacre at Marjory Stoneman Douglas High School, which also left 14 people wounded.

The owners of the small business, located in a strip mall near the school, said they ensured that Cruz had filled out all of the required paperwork which included his driver’s license and assurances that he did not suffer from mental illness. The store owners said, through their attorney, that Cruz only purchased the semi-automatic rifle off the shelf and did not purchase any accessories, modifications, or ammunition so as not to raise eyebrows.
