Alfredo Estrella—AFP/Getty Images The worry now is that the Mexican government’s decision to release Guzman sets a precedent. Not at all. Not at all. Mexican security forces flee after cartel gunmen launch a full-scale war to release El Chapo’s son at drug lord’s bastion Culiacan Ovidio Guzman was briefly arrested after federal police patrol came under fire from a house where he was holed up with three others on Thursday afternoon. Who knows how many people were killed in Culiacán Thursday, but the cartels demonstrate the government of Lopez Obrador has not gotten the best of them. On 17 October 2019, a large convoy of vehicles drove up to Guzmán López's house in Culiacán based on an extradition warrant from a US judge when it came under fire. It had an urban population of 785,800 in 2015 while 905,660 lived in the entire municipality. Culiacán (Spanish pronunciation: ) is a city in northwestern Mexico. The military succeeded in capturing Guzmán López, but quickly found themselves surrounded by cartel enforcers. It is also the seat of Culiacán Municipality.
