Blast outside Oklahoma Memorial Stadium kills one

One person was killed in an explosion in a traffic circle about 100 yards from a packed football stadium at the University of Oklahoma on Saturday night in what authorities were calling a suicide. "We are apparently dealing with an individual suicide, which is under full investigation," OU President David Boren said in a statement. The loud noise of the explosion could be heard inside Oklahoma Memorial Stadium, where 84,000 people were watching the Oklahoma Sooners play Kansas State. Officers cordoned off an area west of the stadium after the explosion and nobody was allowed out of the stadium immediately after the blast, which occurred shortly before 8 p.m., about halftime of the game. People were allowed out about 30 minutes later. (USA Today)
