"He came running and swinging at my neck, as I tried to get out of the way," she said.
Harris County Sherriff Adrian Garcia said that when emergency calls came into the department, there were indications that "students or faculty were actively responding to work to subdue this individual."
"So we're proud of those folks, but we're glad no one else is injured any more severely than they are," Garcia said.
Media and police swarmed the quiet neighborhood about 10 miles from the campus after the attack. Some neighbors described him as quiet, and noted that he didn't appear to have many friends, staying indoors most of the time unless his parents were outside working in the yard.
Michael Lincoln, who lives next door to the Quick family, described the suspect as friendly.
"If he's outside, he speaks to me, 'Hey neighbor, how you doing?"" Lincoln said.
He added that Quick had never been aggressive, which makes the accusations against him shocking.
"He stayed inside most of the time unless they were doing yard work," he said.
Elva Garcia, 46, who lives two houses down from the Quicks, described him as a nice young man who stayed out of trouble and only came outside with his parents. She saw him, she said, just this past weekend, working with his parents in the front yard.
"We can't even believe it. What motive would he have?" Garcia said.
The attack came three months after a different Lone Star campus was the site of a shooting in which two people were hurt. The suspected gunman in that incident is charged with aggravated assault.
