People have been seen on CCTV fleeing a masked gunman who killed nine before he was shot dead by police outside a bar in Ohio.
Officers gunned down Connor Betts, 24, after he opened fire in a popular entertainment district in the city of Dayton.
The attack came just a few hours after 20 people were killed in a mass shooting in El Paso, Texas.
Police said Betts, whose 22-year-old sister was among his nine victims, was wearing body armour and carrying a .223-caliber rifle with magazines capable of holding 100 rounds of ammunition.
Footage showed panicked people fleeing from outside a bar as the 24-year-old opened fired.
CCTV later showed police officers shot him dead before he could enter the premises.
Police chief Richard Biehl said the gunman was killed no more than 30 seconds after the attack began.
Bett’s sister Megan was the youngest of the dead.
The other victims were identified as Monica Brickhouse, 39; Nicholas Cumer, 25; Derrick Fudge, 57; Thomas McNichols, 25; Lois Oglesby, 27; Saeed Saleh, 38; Logan Turner, 30; and Beatrice N. Warren-Curtis, 36.
Mayor of Dayton Nan Whaley said at least 27 more people were treated for injuries.
The gunman was a familiar face at another bar in his hometown Bellbrook, southeast of Dayton.
Bartender Andy Baker said he saw Betts at Romer’s Bar & Grill last Monday and seemed fine.
Fellow customer Mike Kern said he sometimes played trivia at Romer’s with Betts, who was good for answers about current affairs and popular culture and was “the kind of kid you’d want as a son”.
He added: “I never heard him talk about violence, say a racist word, or anything like that.”
The gunman was white and six of the nine people killed were black, police said.
Although they’ll investigate the possibility of a hate crime, they said the quickness of the rampage made any discrimination in the shooting seem unlikely.
Bellbrook Police Chief Doug Doherty said he and his officers weren’t aware of any history of violence by Betts, including during high school.
They added they had no previous contact with him.
