No, nothing to do with mental illness.

Via USA Today:

A white, middle-aged gunman, in what appears to be a politically motivated anti-government attack linked to immigration, fired more than a hundred rounds at buildings in downtown Austin early Friday and tried to set fire to the Mexican consulate before he died of a gunshot wound.

The unidentified suspect was described as white male in his 50s with a criminal record.

Police were investigating whether the gunman was killed by a police officer who fired at him in front of police headquarters or died of a self-inflicted gunshot wound.

The police chief said the suspect’s targets indicated that he might have had anti-government motives linked to immigration.

“If you look at the targets, it doesn’t take a genius (to suggest) that that is the potential,” Acevedo said.

“I would venture that political rhetoric might have fed into some of this, but that is speculation on my part,” he added.
