**Update 10/9/15 7:10 a.m. — NAU Police Chief Greg Fowler has identified the shooter as 18-year-old freshman Steven Jones. Jones is police custody and is said to have opened fire following an altercation in a parking lot.
**Update 10/9/15 12:15 p.m. — NAU has released the names of the four victims: Colin Brough was fatally shot, while Nicholas Prato, Kyle Zientek, and Nicholas Piring are being treated at Flagstaff Hospital. Their conditions remain unknown.
One person is dead and three others are wounded following an early-morning shooting at Northern Arizona University, according to officials at the Flagstaff campus.
A statement from the University reports that the shooter is in custody and that the three injured victims are being treated at a Flagstaff hospital.
The first call to the police about gunfire outside Mountain View Hall occurred at 1:20 a.m., and the dormitory was temporarily put on lockdown.
Tweets from NAU show that by 3 a.m., the situation was stabilized and that the shooter was apprehended.
No details have been released so far about the identity of the victims, but concerned parents are encouraged to call 928-523-0007. Additionally, a Family Assistance Center has been set up in the ballroom of 1899 Bar & Grill, 307 West Dupont Avenue in Flagstaff.
The shooting — the 295th so far this year nationwide in which four or more people have been shot — comes just eight days after 26-year-old Christopher Harper-Mercer opened fire on Umpqua Community College killing nine and injuring nine others. Harper-Mercer committed suicide during a subsequent shootout with police.
The incident reignited a national debate about gun control and mental health services in the country.

Earlier this year, Arizona State University professor Sherry Towers published a study showing that mass shootings are contagious. According to Towers' research, within 13 days of a shooting with four or more victims, there is a heightened probability of another shooting occurring — about 20 percent to 30 percent of mass killings happen during these so-called infectious periods.
NAU officials are expected to give a live press conference sometime Friday morning. New Times will post new information as it becomes available.
