On October 6, 2019, gunfire erupted inside Tequila KC bar in Kansas City, Kansas, during a night that had started with about 40 patrons. A dispute earlier in the evening involving two men — 23-year-old Javier Alatorre and 29-year-old Hugo Villanueva-Morales — led to their ejection after one reportedly threw a cup at the bartender. The two returned armed and opened fire into the crowd.

The shooting left Francisco Garcia Anaya, 34, and three other men dead: Everardo Meza, 29; Alfredo Calderon Jr., 29; and Martin Rodriguez-Gonzalez, 58. Five additional people were wounded. Alatorre was arrested the next day in Kansas City, Missouri; Villanueva-Morales fled to Mexico and was arrested there in December 2019. Both were charged with four counts of first-degree murder.

What details about that evening or the victims’ lives might help clarify how the dispute escalated into such deadly violence?
