Panicked children and teachers placed half a dozen calls to 911 emergency services from the Texas classrooms where a massacre was unfolding, according to an official on Friday, who also said that a teacher propped open a door minutes before the shooter entered.
At least two children called the 911 emergency number from the two connecting classrooms after 18-year-old Salvador Ramos entered with a rifle, said Steven McCraw, director of the Texas Department of Public Safety.
