NASHVILLE – A growing crowd of mourners stood shoulder-to-shoulder in front of the Metro Nashville Courthouse steps and filled the grass plaza Wednesday afternoon ahead of the evening’s citywide vigil.

Some stood quiet, arms crossed, holding small white candles and waiting, focused on the courthouse doors. First lady Jill Biden visited The Covenant School earlier and stood alongside the rest of the vigil’s attendees as the event began Wednesday night.

Nashville Mayor John Cooper stepped up to the podium first.

“Just two days ago was our city’s worst day,” Cooper said. “… I so wish we did not need to be here, but we need to be here — together as a community.”

To the grieving parents, friends and family, Cooper said they’re not alone. “A grieving city joins you,” he said. “A grieving country.”

Two officers stopped ‘calculated and planned’ attack

Two police officers are being hailed as heroes for their role in ending the shooting rampage at a local Christian elementary school that left three young children and three staff members dead.

Rex Engelbert and Michael Collazo are the officers whose body camera videos from inside The Covenant School were released by the Metro Nashville Police Department. They were among dozens of Metro Nashville police who descended on the building after the first 911 call came in at 10:13 a.m. Monday – an active shooter was roaming the school’s halls.
