Police in Kansas City, Kan., said they are searching for two people involved in a bar dispute early Sunday morning that left four people dead and five injured.

The city’s police department said that two men wielding handguns walked into the Tequila KC bar at 10th Street and Central Avenue in Kansas City about 1:27 a.m. and opened fire, sending panicked patrons fleeing into the street.

On Sunday evening, the department released surveillance cameras with photos of two men – both wearing baseball jerseys, including one from the Kansas City Royals – and asked for the public’s help in identifying them.

The investigation is ongoing, but police said they don’t believe the attack was random or a hate crime.

“There was a disturbance or a fight in the bar earlier that evening, and we’re investigating whether people removed from the bar or who left after the disturbance came back,” a police spokeswoman said.

Police spokesman Thomas Tomasic told reporters at the scene that police are interviewing patrons at the bar whose stories “varied a lot” given the hour of the attack, and that the investigation will “go from there.”

The injured, who range in age from their 20s to the 50s, were taken to four nearby hospitals, and two have been released with minor injuries, authorities said. Police said the four dead were Hispanic males but gave no further details.

Sunday morning’s tragedy came as an off-duty Wyandotte County deputy in his 50s was shot and killed at his home Saturday night in an incident police said is not related.

Sunday’s attack was the latest shooting to strike the area. In April, one man died and three others were injured in a shooting outside a home on Michigan Avenue.

In 2014, a former “grand dragon” of the Ku Klux Klan, Frazier Glenn Miller Jr., shot and killed three people outside a Jewish community and retirement center in Overland Park, Kan. He was convicted and sentenced to death the following year.
