'Just started running': Son calls mom after Polk County bus crash

A Florida mom frantically grabbed her keys, ran out the door, and started driving to her son, who called her moments earlier letting her know that his school bus has been in a crash and flipped over. He's OK. She shared her story with FOX 35's Manny Martinez. In total, 2 people were killed, including a 10-grade student and another driver, and 39 people were hurt in the multi-vehicle crash, officials said.
