Duncan, OK - Three people have been fatally shot, including the gunman, at the Duncan Walmart Monday morning.
Two men and one woman were killed in the parking lot by a gunman with a handgun. The gunman is reported to be among the dead.
Two people were shot inside of a vehicle and one was shot outside.
No more information about the circumstances are immediately available.
Gun-control activist Shannon Watts took to Twitter after the shooting to suggest that the gunman never could have killed anybody if it were simply illegal to possess guns in the Walmart parking lot.
We're fairly certain she's serious.
