This is an accepted version of this page On August 4, 2019, 24-year-old Connor Betts shot and killed nine people, including his brother,[a] and wounded 17 others near the entrance of the Ned Peppers Bar in the Oregon District of Dayton, Ohio.

A search of the shooter's home found evidence that showed an interest in violence and mass shootings and that he had expressed a desire to commit one.

[11] Two hours before the shooting the gunman was seen entering a bar with his brother[a] and a friend in the downtown Oregon Historic District of Dayton.

[12] At 1:05 a.m. eyewitnesses reported that a man opened fire at the entrance of Ned Peppers Bar in the Oregon Historic District.

[15][16][17] According to Dayton Police Chief Richard Biehl, 20 seconds after the shooting began,[8] law enforcement officers were already on the scene and engaged with the gunman.

[21] Police evacuated many nearby night venues and warned Dayton residents to stay away from the Oregon Historic District.

[3][4][25] An autopsy showed that a woman who was shot by Betts was already bleeding from a fatal gunshot wound when she was struck by two bullets that were fired by police.

[35][36] An investigation concluded by the FBI in 2021 found that Betts "acted alone and was not directed by any organization or aligned to any specific ideological group," and that he "fantasized about mass shootings, serial killings, and murder-suicide for at least a decade".

[10][40] On August 5, Dayton Police Chief Richard Biehl stated that: "We have a lot of evidence still to go through ... based on where we're at now, we are not seeing any indication of race being a motive.

[45] Local leaders and community members held a vigil on East 5th Street on August 4, where ten doves were released, one each for each dead victim and one for the injured.

[46] Following the shooting, Ned Peppers Bar posted a message on Instagram reading: "All of our staff is safe and our hearts go out to everyone involved as we gather information.

Representative Ted Lieu, a Democrat, asserted that McConnell was "blocking" the bipartisan proposal on "common sense gun safety legislation" from being voted on in the Senate.

[53] Her statement was criticized by Cincinnati City Council member Chris Seelbach, Butler County Sheriff Richard K. Jones, and Ohio Republican Party chairwoman Jane Timken (who called on her to resign).

[54] Following the El Paso shooting, which occurred 13 hours prior,[11] multiple Democratic 2020 presidential election candidates called for political action to eliminate gun violence in the United States; they included Cory Booker,[55] Pete Buttigieg,[56] Tim Ryan,[57] Bernie Sanders,[58] Elizabeth Warren,[58] and Andrew Yang.

The White House published photos and videos of his trip, some of which showed him posing, smiling, and giving thumbs up gestures with his hosts.

"[61] Comedian Dave Chappelle hosted a free concert for Dayton three weeks after the shootings to honor the victims and their families.

[66] After the attack, artists, performers and avid fans of the genre were outraged after outlets such as Vice attempted linking pornogrind's obscene themes to the gunman's motives.
