Charges were filed early Monday morning in a Saturday night shoot-out that injured an officer and left the ringleader of an alleged drug cartel dead.
The two surviving members of the possible drug ring -- Augustin Toscano, 29, of the 2100 block of West Cullerton, and Raul Seguar-Rodriguez, 36, of the 3000 block of South Keeler -- are charged with three counts of first-degree murder and three counts of attempted first-degree murder.
Lt. Nick Roti said police had been actively investigating the cartel for months when they found two men stabbed to death in an apartment in the 5800 block of North Winthrop Avenue.
Arturo Ibarra, 37, Toscano and Seguar-Rodriguez fled the apartment building and gave chase to officers across Edgewater.
The three rammed into a marked squad car and fired shots, striking an officer in the leg. The chase continued with the suspects reportedly continuing to fire shots at the officers until police stopped the car and returned fire, shooting and killing Ibarra.
Roti said the cartel, which may be linked to a dozen murders, lured customers with cocaine and killed them.
The injured officer is recovering this morning. Toscano and Segura-Rodriguez are scheduled to appear in court Monday.
