Officers fatally shot a patient at a Dallas-area hospital who had a gun in an emergency room, authorities said.

A nurse called police Wednesday night after she saw that the 34-year-old patient had a gun at Baylor Scott & White Medical Center in Irving, said city police spokesman Robert Reeves.

A hospital officer and an Irving police officer confronted the man, who opened fire, Reeves said. The officers fired back, killing him.
