It was a bittersweet feeling for viewers of ABC’s World News Tonight, as host David Muir returned to the network following a brief hiatus.

The 51-year-old journalist’s return came with a slew of heartbreaking news, and one story in particular left fans feeling uneasy. Speaking to viewers from his iconic ABC news desk, David announced, “Back in the US tonight, there has been a workplace shooting, a standoff for hours and word tonight that two supervisors have been killed.”

“Here’s Stephanie Ramos tonight,” the star added, as he passed on to his colleague who was reporting live from where the incident took place.

Clips played of cops gathering outside of the location where the shooting took place, as Stephanie could then be heard in a voice-over explaining, “The 10th hours long standoff in Cleveland, Tennessee, after a deadly workplace shooting.”

Then what appeared to be a cop radioing in an update on the situation played, as a man could be heard saying, “Caller advised they heard a gunshot. They’ve got a female screaming.”

Stephanie continued, “The horror unfolding shortly before 10:30 this morning, gunfire erupting at the Barku plastics plant just outside Chattanooga, two male supervisors shot and killed.”

Another police radio call was then heard, as the cop shared, “They’re advising suspect left in a black BMW, unknown direction of travel,” before the reporter gave more context to the developing stoty, “Police tracking the suspect, who is also an employee to what is believed to be his home just miles away, SWAT teams swarming the scene. Late today, authorities say the suspect was found dead.”

Stephanie concluded her reporting, telling David back in the studio that officials are still trying to figure out what prompted the man to open fire as they continue their investigation.
