…"They soon heard people yelling, and walkie-talkies crackling, and then they heard police asking someone to drop the gun, put the gun down, and hold his arms up, she said. She did not hear another gunshot, though the people doing the talking could have moved farther away, she said. Soon, they heard police ordering them out."
