The state medical examiner’s office has revised the death toll from a tornado in an Oklahoma City suburb to 24 people, including nine children.

Spokeswoman Amy Elliott said Tuesday morning that she believes some victims were counted twice in the early chaos of the storm. Authorities said initially that as many as 51 people were dead, including 20 children.

Elliott says nine children are confirmed dead, including seven who were pulled from the wreckage of an elementary school in Moore, 10 miles south of Oklahoma City.

Teams are continuing to search the shattered community after the Monday afternoon tornado.
