Seven suspected undocumented immigrants were killed and eight others injured when a truck being chased by police crashed into a security barrier at a Navy facility in Texas, authorities said Thursday. Fifteen people were in the truck, with 10 crammed inside the cab and five under a tarp in the truck’s bed, said John Gagne, spokesman for Naval Air Station Kingsville. The crash occurred late Wednesday when the extended-cab pickup sped past an officer at the main gate at the base, south of Corpus Christi, Gagne told CNN.
