A woman whose name has not been released also received medical treatment. It was initially believed she suffered a heart attack, but Garcia said she was treated for an anxiety attack.
Berry is scheduled for a court hearing Thursday, which could be delayed because of his medical condition, officials said. He faces a total bond of $60,000.
The volley of gunshots around noon Tuesday at the college, located in north Houston, prompted a lockdown then evacuation of the campus. Students were allowed to return to campus and retrieve their vehicles later Tuesday. Classes at the campus resumed Wednesday.
Steve Head, president of the college campus, said at the news conference that employees and students who returned to school Wednesday had questions and were a bit jittery, but he said overall it was a "good day."
"The students are concerned but we are trying to emphasize that this is an isolated incident," he said.
Head said the school was reviewing its procedures, including whether the campus alert system notified people as quickly as possible.
