An out-of-control monster truck shot into a crowd of spectators at a Mexican air show, killing eight people and hurting 79, officials said. The driver was detained Sunday on suspicion of manslaughter and officials said they were investigating possible safety violations in the setup of the show. Carlos Gonzalez, spokesman for the Chihuahua state prosecutors’ office, said driver Francisco Velazquez appeared to lose control of the truck after leaping over cars it was crushing during a demonstration at the "Extreme Aeroshow" on Saturday.
