[PAR] [TLE] 2015 Tanhuato–Ecuandureo shootout [SEP] On May 22, 2015, a three-hour shootout broke out between the Mexican Federal Police and alleged members of the Jalisco New Generation Cartel (CJNG) in Tanhuato and Ecuandureo, Michoacán, leaving 43 dead.  One of the fatalities was a Federal Police officer, while the others were suspected to be organized crime members.  The confrontation started when the Federal Police spotted a suspicious vehicle on a highway.  The authorities had received information that one of the properties in the area had been overrun by criminals.  Unconfirmed reports suggested that the CJNG leader Nemesio Oseguera Cervantes was in the area.  When they tried to pull over the vehicle, however, the men onboard opened fire at the police units.  A vehicle chase ensued and the security forces made their way into a large, rural property where the shootout intensified.  The Federal Police then called for ground and air reinforcements and neutralized the situation.
