NASHVILLE, Tenn. (AP) — Hundreds of people have gathered at a candlelight vigil to mourn the three children and three adults slain in a school shooting in Nashville, Tennessee. The crowd in the city’s downtown was largely somber and silent and filled with young people. First lady Jill Biden and Sheryl Crow were among those featured. So were fellow musicians Margo Price and Ketch Secor. Civic leaders were also in the evening’s lineup. Mayor John Cooper called Monday’s shootings at the private Christian school “our worst day.” Earlier in the day, Pope Francis sent his condolences to the city and offered prayers to those affected.
