Four people were killed and five others wounded after a suspect entered a bar in Kansas City, Kansas early Sunday and started shooting, police said.

Police had responded to the incident overnight at Tequila KC on 10th & Central Avenue after receiving the first 911 call at about 1:27 a.m., according to Thomas Tomasic of Kansas City Police Department.

Authorities do not have a suspect in custody and are working to find surveillance video of the shooting.

"We do not have a good enough description yet to put anything out for suspect or suspects," Tomasic said. "We don’t even know how many."

The four people who died were all Hispanic males. Authorities did not identify them further. Five others were taken to local hospitals and in stable condition.

Police said they had no reason to believe the shooting was racially motivated and that it appeared to be an isolated incident.

The weapon that was used was a handgun, police said.

Agents from Kansas City's Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) said they were responding to the shooting later Sunday morning.
