On May 4, 2018, at approximately 3:15 a.m., 27 year old Almighty Saints gang member Ernesto “Ernie” Godinez was acting as a lookout for his gang in Chicago's Back of the Yards neighborhood when he opened fire on members of an undercover joint task force who he mistook as rival gang members, striking 28 year old ATF agent Kevin Crump. Crump and other agents were placing court-approved tracking devices on vehicles belonging to suspected gang members during a joint mission by Chicago Police and the Bureau of Alcohol, Tobacco, Firearms and Explosives. Kevin Crump and other members of the strike force were acting on information that the Almighty Saints gang in the Back of the Yards might have just received a number of guns, according to a law enforcement source. Crump was part of the strike force formed in June 2017 to cut the flow of illegal guns into Chicago and crack down on people repeatedly arrested on gun charges. 20 ATF agents were assigned to the task force, along with a number of officers from the Chicago Police Department and the Illinois State Police. No other officers were hurt in the incident, but he was the 4th law enforcement officer shot in the city's Back of the Yards neighborhood in the past year, the Tribune reported.
