Two Bay Area mothers and their four children burned to death in a van Tuesday while their fathers tried to pull them from the flames. The van was hit by a semitrailer after an accident with another car. It fell down an embankment and then burst into flames. “Words can’t describe it,” California Highway Patrol Officer Dan Williams told the Associated Press. “It was very horrific seeing them try to get their families out, us trying to help get their families out.” The minivan driver, 34-year-old Aaron Hon Wing Ng, and front passenger, 45-year-old Wei Xiong Li, escaped. The car was completely engulfed in flames almost immediately, authorities said. Officer Ron Pomeroy said, “Those two gentlemen along with our CHP officers attempted to extinguish the flames and pull the other occupants out of the vehicle, but they were unable. They were overcome by flames.” Eventually, police had to hold Li and Ng back as they hysterically tried to reach their wives and children. They were airlifted to a hospital with non-life-threatening injuries. At least one of the officers was also treated for burns.
