Four people were killed and five wounded in Kansas early on Sunday when one or two suspects opened fire inside a Kansas City bar, and police were hunting for the shooters, local authorities said. Authorities believe the suspects had been involved in a dispute at Tequila KC Bar, a private club, earlier in the night and left before returning around 1:30 am and opening fire with handguns, the Kansas City Police Department said in a statement. The four people killed were all Hispanic men and ranged from their mid 20s to late 50s.
