Sacramento police said they were still searching for a sole suspect, whom they described on Twitter as a “male Tongan, white shirt/beige cargo shorts, last seen fleeing (on) foot from the shooting.”

The gunman opened fire on the busy Sacramento City College campus Thursday afternoon killing one person and left two  people with serious injuries.

Sacramento Police Department spokeswoman Traci Trapani said the attack appeared to be an “isolated incident” rather than a campus shooting spree.
