Flags are being lowered and a vigil is planned Tuesday night in Dunwoody as local communities respond to the mass murder of at least 58 concertgoers in Las Vegas on Oct. 1.

The murders, reportedly committed by a gunman who killed himself after shooting into a country music festival from a hotel tower, were widely condemned by local officials and candidates on social media.

“The City of Atlanta stands with Las Vegas,” said Atlanta Mayor Kasim Reed on Twitter. “Our thoughts & prayers are with the victims of yet another cowardly & senseless act of violence.”

A group of mothers is organizing a candlelight vigil to be held Tuesday, Oct. 3, 8:30 p.m. in Dunwoody’s Brook Run Park, 4770 North Peachtree Road.

“There will be no protests or speakers, just a chance for our community to come together in grief,” said organizer Jill Vogin in an email announcement. “Some of us will stand quietly, while others will walk the path along the field.”

Vogin said the vigil organizers are an informal group of friends who began planning their own events following the white nationalist rally in Virginia in August where a protester was killed by a participant. “We started an email list after Charlottesville so we can organize local vigils rather than having to go downtown to do so,” she said.

In Buckhead, Covenant Presbyterian Church will hold a special “prayer service of lament and healing” open to all in response to “the act of unspeakable gun violence in Las Vegas,” according to a press release. The service will be held Wednesday, Oct. 4, 7 p.m., at the church at 2461 Peachtree Road N.E. “All who need a space to grieve and pray are welcome,” the church said.

Flags were lowered to half-staff to honor the Las Vegas victims in the cities of Atlanta and Dunwoody and the counties of DeKalb and Fulton.

State Sen. Elena Parent (D-Atlanta), whose District 42 includes part of Brookhaven, retweeted some gun-control-related posts with her own comments, which included a reference to the Pulse nightclub mass murder in Orlando, Fla., last year. “I am furious that America’s gun violence epidemic reached a new height w[ith] deadliest mass shooting ever, supplanting Pulse barely 1 yr ago,” Parent said in one tweet, adding in another, “Exactly why the notion of ‘politicizing’ the aftermath of a mass shooting is laughable–it’s an excuse for those wanting to avoid the issue.”

The following are some reactions by local officials and candidates on social media:
