Tulsa Police Department Deputy Chief Eric Dalgleish says dispatchers received a call about an active shooter at the Natalie Medical Building, a physicians' office building on the St. Francis Hospital campus.

According to the deputy chief, the officers who arrived could hear shots inside the building, which directed them to the second floor.
