The Santa Barbara County sheriff describes it as quote -- "the work of a madman."
At least six people are confirmed dead from a drive-by shooting near the University of California at Santa Barbara.
Spraying bullets from his car, the gunman wounded seven others before crashing the vehicle.
Witnesses couldn't believe what they heard:

"Around 930 or so we started hearing pops in the background. We heard about five or six and then there was a long pause and then we heard another five. We thought they were fireworks because in IV (Isla Vista) it's pretty normal to hear fireworks going off."
Authorities say the suspected gunman was found dead inside the car, with a bullet wound to the head.
Details are still emerging. But part of the investigation includes a video posted on YouTube that appears to have been made by the suspect.
