Stephen Marlow, a “person of interest,” is likely armed and dangerous, Butler Township Police Chief John Porter told a news conference.
Porter said Marlow is 5-foot-11 and weighs 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 gunfire just before noon, Porter said, and all four victims died at the scene.
“This is the first violent crime in this neighborhood in recent memory,” Porter said. “We are working to determine if there was a motive for this horrific tragedy or if mental illness played a role,” the chief said.
“I would never, even in this neighborhood, expect anything, ever,” Chapman told the Dayton station.
Police do not believe there is an ongoing threat to the neighborhood, but have deployed additional teams and the Dayton Police Bomb Squad out of an abundance of caution, Porter said.
Porter said people should call police dispatch if they have any information about Marlow’s whereabouts or if they see the Ford Edge. He also urged residents in the neighborhood to watch the video footage from last Friday.
Butler Township is a town of just under 8,000 about 9 miles north of Dayton.
