Northern Arizona University said Thursday that one person was dead and three wounded overnight outside a dorm at the university's Flagstaff campus. The suspected shooter is in custody and the campus isn't on lockdown, the university added. NSU spokeswoman Cindy Brown didn't provide many details about the shooting, except that it was first reported at about 1:20 a.m. local time happened outside Mountain View Hall, a dormitory that ABC News says houses most of the students involved in Greek organizations.
