SILVER SPRING, Md. (AP) - A security guard has shot and killed a 7-Eleven customer who police say was involved in a dispute with the cashier.

Citing a Montgomery County police release, news outlets report that 27-year-old Deon Christopher McDonald was found outside the Silver Spring store early Sunday, and died at the scene.

A preliminary investigation found that McDonald was in the middle of purchasing an item when an argument broke out with the clerk, and an armed security guard intervened. The confrontation between McDonald and the guard became physical and spilled outside, where the 44-year-old guard shot McDonald.
