(CNN) -- The mayor of a city in the Mexican border state of Tamaulipas was killed and his 10-year-old daughter was injured Sunday, officials said.
Marco Antonio Leal Garcia, mayor of the city of Hidalgo, was driving a truck on his property around 4:30 p.m. when he was killed, state prosecutors said in a statement.
State prosecutor Hernan de la Garza Tamez said police recovered 18 casings and three shotgun shells at the scene. According to the results of an autopsy, Leal suffered 27 bullet wounds in the head, thorax, abdomen and back regions.
Leal's daughter, who was riding with him, suffered non-life-threatening injuries, prosecutors said. She was injured by two gunshots to the leg, which fractured her tibia, officials said.
"It was not just [an] attack against a person. It was an attack against institutions," Tamaulipas Gov. Eugenio Hernandez Flores said in a statement Sunday night, the state-run news agency Notimex reported.
Mexican President Felipe Calderon's office also released a statement strongly 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 of Tamaulipas," the statement said.
Tamaulipas, which borders Texas, has seen a spike in recent violence. On Tuesday investigators found bodies of 72 migrants.
A young man from Ecuador who led navy personnel to the scene of the massacre said he escaped after pretending he was dead.
Officials are investigating whether the Zetas drug gang carried out the killings, as the young man reportedly told police.
