A pickup truck blew a tire and smashed head on into another pickup crowded with women and children returning from a religious service, killing all eight people in the two vehicles.

Thelma Rodriguez Vasquez and six of her female relatives were heading home from a weekly prayer meeting Thursday night on a remote stretch of highway just northeast of this ranching town.Hugo Rafael Gutierrez may have been speeding when the tire blew on his truck, sending it into the path of Vasquez, said Tom Vinger, spokesman for the Texas Department of Public Safety.
