First, there was a shooting at Northern Arizona University early this morning, leaving one dead and three wounded.
The attack began as a confrontation between two groups of students that "turned physical" before Jones pulled a gun and opened fire, Fowler told reporters and students at news conference.
The shooting occurred in a parking lot near the Mountain View Hall dormitory, where most of the school's fraternity members live, school officials said.
Fowler said he did not know whether the gunman or the victims were members of fraternities. But the national executive director of the Delta Chi fraternity confirmed that members of his organization were among the victims.
A gun always changes the calculus. Perhaps there might have been a confrontation without dead students if there were no guns involved?
Later in the day, there was another shooting near the campus of Texas Southern University.
John Cannon, a spokesperson for the Houston Police Department, said officers responded to calls about a shooting at 11:30 a.m. Friday. One person was fatally shot and another wounded, he said.
The injured person is in serious stable condition, according to the university.
Two persons of interest have now been detained, according to university officials Friday afternoon, but the assailant remains at large.
The campus-wide lockdown was lifted, but the Courtyard Building 1 remains restricted and locked down. All classes were canceled.
