Stephen Marlow, a “person of interest,” is likely armed and dangerous, Butler Township Police Chief John Porter said at a media briefing.
Porter said Marlow was 5’11” and about 160 pounds, with brown hair. Authorities believe Marlow, 39, was wearing shorts and a yellow T-shirt and fled in a white 2007 Ford Edge.
Police responded to a report of shots fired just before noon, Porter said, and the four victims died at the scenes.
“This is the first violent crime in this neighborhood in recent memory,” Porter said. “We are working to determine if there was any motive to this horrible tragedy or if mental illness played any role,” the chief said.
“I would have never, even in this neighborhood, I would never expect anything, never,” Chapman told the Dayton station.
Police do not believe there is an ongoing threat to the neighborhood but have deployed additional crews and the Dayton Police Bomb Squad out of an abundance of caution, Porter said.
Porter said people should call the police dispatch if they have information on Marlow’s whereabouts or see the Ford Edge. He also urged residents in the neighborhood to look at video footage from earlier Friday.
Butler Township is a town of just under 8,000 residents about 9 miles north of Dayton.
