A Denver-based journalist for Fox News had an emotional reunion with her son while reporting live from his high school in the aftermath of a shooting there on Wednesday.

Alicia Acuna, a senior correspondent, halted her coverage outside East High School mid-sentence when she saw her son.

She told anchors John Roberts and Sandra Smith that she had been working on another story on Wednesday when her son texted her that police officers had just interrupted an assembly.

The officers ordered the students to shelter in place, and “I kept in contact with him over text because he had to stay silent,” Acuna explained.

One of the faculty members shot was in critical condition, Denver Police Chief Ron Thomas said in a press conference.

The East High incident on Wednesday was the 18th such school shooting where at least one person was killed or injured, according to data from the Gun Violence Archive.
