Louisville experiences second deadly shooting in one week.

Two people were killed and four others were injured in a shooting at Chickasaw Park in Louisville, Kentucky, less than a week after a mass shooting at a bank in the city left five people dead. Police responded to reports of the shooting around 9 p.m., and two victims were pronounced dead at the scene. The shooter is still at large, and police have no witnesses to the shooting. The incident continues a string of mass shootings in the U.S. that has renewed debate over gun control and gun rights.
