(CNN) A gunman opened fire on people waiting in line to get into a Kansas City bar Sunday night and was stopped by an armed security guard, police said.

A man, who police believe was the shooter, and a woman were found dead in the bar's parking lot. Kansas City police Capt. David Jackson said the armed security guard engaged the gunman in the parking lot.

The suspected shooter was identified as Jahron Swift, 29, and the woman was identified as Raeven Parks, 25, according to Police Chief Richard Smith.

During a press conference Monday, Smith maintained at least 15 people were injured in the shooting and no motive has been identified despite rumors on social media. Authorities are still working to figure out the extent of the injuries among those people, whether they're all gunshot wounds or other injuries, Smith said.

The shooting came hours after the Kansas City Chiefs clinched a trip to Super Bowl LIV , beating the Tennessee Titans at Arrowhead Stadium in Kansas City.
