IRVING, Texas (AP) -- A math tutor at a suburban Dallas community college says she saw a man shoot a woman three times in the hallway of a campus building.
Nasrin Nanbakhsh says the woman was sitting in a chair at North Lake College in Irving when the gunman approached her Wednesday and fired.
Nanbakhsh said she ran into a room, locked the doors, turned off the lights and waited for help to arrive. She said she also emailed her supervisors to let them know what was happening.
Irving police spokesman James McLellan says the gunman took his own life after killing the woman.
The school northwest of Dallas was closed for the rest of the day.
North Lake College is a two-year public school that's part of the Dallas County Community College District.
