The sheriff says four people died after a crash in Camden County between a dump truck and a pickup.  The crash was about 8 a.m. Wednesday on the Niangua Bridge on Missouri 5, five miles north of Camdenton.  

All four people died at the scene.  Three of the fatalities were people in the pickup.  The fourth was someone in the dump truck. 

The highway was closed in that area for six hours as crews worked to clear the scene. Fuel spilled, so a hazardous material cleanup crew was called.

Police have not released the identity of the people killed.
