The gray Ford pickup truck veered into a ditch with such force that people who live on the block assumed it was an accident and rushed over to help the driver.
Instead, according to witness and police accounts, Salvador Rolando Ramos emerged wearing tactical gear and carrying an AR-15-style rifle he bought this month, just after his 18th birthday. Bystanders scattered as Ramos hopped a fence, exchanged gunfire with a school police officer and entered through a side door to Robb Elementary. Inside, he embarked on a deadly rampage that brought the national scourge of school shootings to a fourth-grade classroom in this southern Texas town.
