Marco Antonio Leal Garcia, mayor of the city of Hidalgo, was driving a truck around 4:30 p.m. when he was killed, state prosecutors said in a statement. They did not provide details about the attack.
Leal’s daughter, who was riding with him, sustained non-life-threatening injuries, prosecutors said.
“It was not just attack against a person. It was an attack against institutions,” Tamaulipas Governor Eugenio Hernandez Flores said in a statement Sunday night.
He said police were still investigating the attack, and called on federal authorities to send reinforcements to the state in response to a notable increase in crime.
Mexican President Felipe Calderon’s office released a statement condemning the attack.
“This cowardly crime and reprehensible violent acts which occurred recently in this state reinforce our commitment to use all the resources of the Mexican state to continue fighting criminal gangs seeking to intimidate the families Tamaulipas,” the statement said.
