CHICAGO - A shooting at a shopping mall in the US Midwest state of Indiana Sunday evening left four dead, including the gunman, and two injured.

The shooting happened in the food court of the Greenwood Park Mall south of Indianapolis, capital of Indiana, around 6 p.m. local time (2200 GMT). An adult male carrying a rifle and several magazines of ammo walked into the food court and began shooting.

Three people were killed and two others were injured, said Greenwood Police Chief James Ison at a press briefing. Police believe an armed bystander killed the gunman at the scene.

The gunman's motive remains unknown.
