In the hours after a lone gunman killed 19 children and two adults at a Texas elementary school on Tuesday, the victims have begun to be identified.

While some families made desperate pleas online to help find their missing children, other families mourned the loss of loved ones following the massacre at Robb Elementary School in the town of Uvalde, a seven-square-mile community located about 85 miles west of San Antonio.

Some names of those killed began to emerge by nightfall on Tuesday, many accompanied by photos of smiling children.

What we know so far

Officials did not immediately reveal a motive, but they identified the assailant as 18-year-old Salvador Ramos, a resident of Uvalde. Law enforcement officials said Ramos acted alone and was killed by a Border Patrol agent who rushed into the school without waiting for backup.

The assault at Robb Elementary School was the deadliest shooting at a U.S. grade school since a gunman killed 20 children and six adults at Sandy Hook Elementary in Newtown, Connecticut, almost a decade ago.
