In the No. 4 lane was a big rig driven by Byron Vasquez, 26, of Los Angeles. Zizi didn’t know how fast both drivers were traveling. “For unknown reasons, (Vasquez) swerved to the right then to the left which caused his rig to lose control,” Zizi said. The truck went across all lanes, heading toward the Focus. He said it broadsided the car and pushed it toward the center divider, where it was pinned. Many drivers from both directions stopped to help. While some kept Marrott alert by talking to her, others called 9-1-1 and several tried to direct traffic, Zizi said. “It was a group effort out there. Fortunately no one got hit,” he said. Zizi believes that the good Samaritans around the Focus were trying to talk to Marrott to keep her from looking in the back seat where her daughter was. Firefighters with the Los Angeles County and the Santa Fe Springs fire departments had to extricate mother and child from the Focus. Grant was pronounced dead at the scene. Zizi didn’t know where Marrott was heading that day. Due to her injuries, officers haven’t been able to interview her. Two northbound lanes were closed for five hours because of the crash and subsequent cleanup.
