A negotiator stationed at a funeral home near Robb Elementary as the Uvalde school shooting was unfolding was trying "every number they could find" to reach gunman Salvador Ramos, the city's mayor has revealed. 

Uvalde Mayor Don McLaughlin, in an interview with The Washington Post, said the negotiator ultimately was unable to make contact with the 18-year-old, who killed 19 students and two teachers in the attack

"His main goal was to try to get this person on the phone," McLaughlin said. "They tried every number they could find." 

The mayor told The Washington Post that he doesn’t believe the negotiator was aware that there were children calling 911 from inside the classroom that Ramos entered, asking police for help.
