Dozens look on at the mangled wreckage of two cars that collided in Houston, Texas, killing mother Silvia Zavala. Police say a teenager is responsible for Zavala’s death. Investigators say the 14-year-old was driving an SUV with other teens who were throwing eggs at cars. That’s when one car started chasing them on the road. The teen then ran a red light, crashing into Zavala’s pickup truck, police say.
