San Francisco's police chief says officers have shot and killed a man who was pointing a rifle at a hospital from atop an adjacent construction site.
Police Greg Suhr said the unidentified man opened fire on officers responding to reports of an active shooter near California Pacific Medical Center's St. Luke's campus on Wednesday afternoon.
Suhr says three officers confronted him at the building site where a new hospital is under construction and fatally shot him. No one else was injured.
Suhr says investigators think the gunman came to San Francisco after acquiring the rifle and ammunition during an armed robbery at a sporting goods store south of the city.
He says they do not yet have a motive.
The hospital was locked down for about an hour as police warned people to stay away from the area.
