Dayton Police Department said the gunman went to the district on the night of 2 August and returned with his sister and a friend at 11pm the following night. “He was not unfamiliar with this territory,” Chief Richard S. Biehl said.
After visiting a bar with them, the gunman left after midnight, the officials said, walking past a police vehicle to go to his car.
They said he went there about 15 minutes before the shooting to retrieve an AR-15-style rifle, ammunition and body armour. He returned wearing a dark hoodie and carrying a backpack, which contained the weapon, they said.

He text his sister and another victim minutes before he started shooting.
“We have radically different views in this regard,” Mr Biehl said of the many officers who reviewed the video evidence. “Based on the evidence of that night, I don’t think we can make that call.”
The gunman started shooting at 1.05am, striking 26 people in less than a minute before he was fatally shot by an officer. The chief added that the gunman did not wear his body armour in the most protective manner.
“Their response was crucial,” Mr Biehl said of his officers. “Their response was immediate. Their response was effective. And their response was compassionate.”
Mr Biehl did not say whether any victims were struck by bullets fired by his officers, leaving that ruling to the coroner’s report.
