Four people have been shot dead, including a mother and her daughter, in a small Ohio town.
Police were called over reports of shots fired in Butler Township, just north of Dayton, shortly before noon on Friday, Butler Township Police Chief John Porter said at a news conference.
They found the bodies of four victims in multiple locations, Mr Porter said.
Police are looking for Steven Alexander Marlow, 39, in connection with the murders.
He is described as 5’11” (180 cm), 160 pounds (72 kg), with brown hair, blue eyes, and possibly driving a white 2007 Ford Edge with registration number JES 9806.
He was last seen in shorts and a yellow shirt.
“If anyone sees Marlow or the vehicle they should call 911 immediately as he is likely armed and dangerous,” Porter told reporters.
“This is the first violent crime in this neighborhood in recent history,” he added.
A man told WHIO that his daughter and granddaughter were among the victims.
There was a large police presence at the scene of the shooting Friday afternoon.
WHIO reported that the police had sealed two houses on Hardwicke Place with masking tape.
Butler Township is a town of just under 8,000 residents about eight miles north of Dayton.
