As reported Tuesday the evening, the death toll in the Robb Elementary School Shooting stands at 19 students and 2 teachers.

One of the teacher’s identities has already been revealed, Eva Mireles, but we are now starting to learn of the identities of the children as families take to social media to mourn their loss.

Benito Martinez, one of the children killed is encouraging parents across the country to hold their own children close, as they never know when it will be the last time.

“For everybody else that has kids out here, cherish these moments just like your parents cherished you every day,” Martinez, a family member of the deceased told Fox News. “Tomorrow’s not promised, so make today worth it.”

As originally reported by Fox News, Martinez is the uncle of fourth-grader Xavier Lopez, 10, who was killed when a gunman broke into the school and fatally shot at least 19 children and two teachers.

“I am still trying to process everything that is going on,” he said during an interview with Fox News Digital.

Martinez and his own four children visited the school after the shooting to pray about the loss of young Xavier and to pray for the others who lost loved ones.

“I believe in the power of prayer, especially in circumstances such as this,” he said.

“I am going to pray, and I am going to keep them in my prayers as well,” he continued. “They are mourning the same way. You don’t expect to take your kids to school and think today is the last day you are going to see them.”
