When firefighters arrived on scene, they found one male victim dead and other suffering from serious injuries, Fontana police Sgt. Robert Morris said.

“Based on their preliminary investigation it appears that both men were working outside in an area used to coil cable under high pressure,” Morris said. “While the cable was being rolled into coils it appears that a portion of the cable possibly snapped causing the cable to strike both men.”
