Editor's Note: Early reports indicated five people were killed. It was later clear that number included the attacker. Additionally, more injuries have been reported. This story has been updated to reflect this information.
At least four people were killed and eight others, including a police officer, were injured after an individual opened fire inside of a bank building in downtown Louisville near Slugger Field, the Louisville Metro Police Department said Monday morning.
The suspected lone shooter also died at the bank, Louisville Metro Police Chief Paul Humphrey told reporters at a news conference Monday morning, though it was not immediately clear if the shooter was killed by police or died by suicide.
According to officials, Louisville police just after 8:30 a.m. responded to a call of shots fired at Old National Bank at 333 E. Main Street. When officers arrived, they encountered an active shooter inside the building, Humphrey said.
Around 9:15 a.m., Louisville police posted an update saying "there is no longer an active aggressor threat," adding that the suspected shooter had been "neutralized."
Humphrey said the eight wounded victims were hospitalized at University of Louisville Hospital in varying conditions. At least one of those injured was a Louisville Metro police officer.
