The driver of a tractor-trailer dump druck had a heart attack, crossed the center line and side swipped another dump truck on Rt. 173 west of Rt. 59 in Antioch. The two trucks ended up a few 100 yards from each other. Several cars headed for the hills as the Mack dump truck shot down the road out of control. The Antioch Fire & Rescue Squad arrived at the scene to find cars off the road on both sides of Rt. 173, one truck inside the boat storage area leaking fuel and the other on it's side blocking the highway. The driver of the Mack did not survive and the driver of the Peterbuilt was transported by Antioch Rescue.
