People were gathered in the entrance to a nightclub in Amarillo when a vehicle pulled up at about 2:05 a.m. on Jan. 26 and a gunman exited the vehicle, opening fire into a large crowd with a rifle, the Amarillo Police Department said in a statement.

The Amarillo Police Department announced it would hold a press conference Monday morning in the wake of the Sunday mass shooting that killed one person and injured eight others at a South Polk Street nightclub.
