The exact subject of the argument that led to a shooting a Houston-area community college hadn't been determined Wednesday, but Harris County Sheriff Adrian Garcia said he had a general idea of the cause.

"Idiocy. Stupidity," Garcia told reporters. "We had individuals who did not care about putting other people in harm's way. It was a ridiculous, adolescent confrontation that occurred. But if we can make an example out of anyone, we will."

Pressed for details, Garcia added, "We're still clearing that up. But a confrontation occurred, and somebody thought, in their peanut-sized brain, that maybe a firearm on a campus would be the way to settle it."

Garcia's blunt assessment came a day after three people were wounded at Lone Star College. One of those shot, 22-year-old Carlton Berry, has been charged with two counts of aggravated assault and remains under guard at a hospital, Garcia said. The other two were still hospitalized as well, he said.
