Nancy Grace weighed in Thursday morning on the Texas mass shooting that claimed the lives of 19 children and two adults.

As CrimeOnline previously reported, numerous children were killed Tuesday morning when 18-year-old Salvador Ramos opened fire at Robb Elementary School in Uvalde, just two days before the end of the school year.

Law enforcement sources not authorized to speak publicly told the AP that a Border Patrol agent was in the area when the shooting started and rushed into the school without waiting for backup. The agent, who was wounded, shot and killed the gunman, who was behind a barricade.

Uvalde Consolidated Independent School District Police Chief Pete Arredondo told reporters that “the intruder is deceased, and we are not looking for anyone else.”

Multiple agencies — federal, state, and local — responded to Robb Elementary School just after 11:30 a.m. Tuesday morning on reports of the shooting. Ramos is believed to have been shot and killed by law enforcement

“This guy, so full of hate and evil, that he guns down little children,” Grace told Fox Digital News, adding that the killer planned the shooting after posting photos of guns and bags of ammo.

“I feel like we’re failing parents.”

Uvalde is a small town about 80 miles from San Antonio. Nearly 75 percent of its population is Hispanic. Robb Elementary has about 600 students, all second, third, and fourth-graders.
