AUSTIN - A man apparently upset about US immigration policy was fatally shot on Friday after firing more than 100 rounds of ammunition at buildings including the Mexican consulate, a US courthouse and police headquarters in the Texas capital, police said.
Police identified the gunman as Larry McQuilliams, 49, an Austin resident with a criminal history.
Police said they were investigating whether McQuilliams died of a self-inflicted wound or from a shot fired by a mounted officer who was bringing horses into a stable near police headquarters.
No one else was injured in the incident, police said. "The sergeant was right there getting ready to put the horses away for the night," said Austin Police Chief Art Acevedo.
"As he held two horses with one hand, he discharged at least one round with a single-handed shot." McQuilliams also tried to set fire to the Mexican consulate, police said.
In a statement, the Mexican Foreign Ministry expressed its"deep concern and condemnation of the incident." Acevedo said the targets indicated the attack may have been over US immigration policy.
"When you look at the national debate right now about immigration, that ... comes to mind. Sometimes our political discourse becomes very heated and sometimes very angry," Acevedo told reporters.
President Barack Obama this month imposed the most sweeping US immigration changes in a generation, easing the threat of deportation for some 4.7 million illegal immigrants.
Police said they received a call at 2:22 a.m. about shots being fired in downtown Austin. No bombs were found on the suspect or in his vehicle, Acevedo said. Police examined McQuilliams' home in north Austin and said "the residence has been secured and is safe."
