Israel Patrón, the Michoacán state director of public security, said the police convoy consisted of 41 police officers who were going to pick up a woman and her daughter to testify as victims of domestic violence.
As they were crossing through the village of El Aguaje, they were attacked from behind by the armed gunmen, he said. The attack also injured three officers.
Federal and state forces, including the National Guard, were conducting a manhunt to find the attackers, Mr. Patrón said.
It “is not new in terms of violence,” Mr. Ernst said. “It’s more concentrated so you are producing a spectacle. So there is a symbolic language behind this.”
The Jalisco cartel has a history of attacks on state forces, he said, while their rivals in the state, the Knights Templar and the Viagras, try to maintain a better relationship with the police. The Jalisco Cartel is moving from the mountainous border between Jalisco and Michoacan into the Tierra Caliente region.
Control over that territory allows criminal gangs to produce drugs — including methamphetamine — and exert control over the local avocado and lime industries, Mr. Ernst said. The National Guard has been deployed in some parts of Tierra Caliente.
“It’s positive that the government is trying to address root causes” of crime, Mr. Ernst said. “But there is no short-term component of the strategy and that allows regional conflicts to spin out of control.”
Meanwhile, civilians are left unprotected in lawless regions like the Tierra Caliente, he said. “It’s an ad hoc policy that is driven by daily events.”
