AKRON, Ohio—Four adults who had been shot in their heads were found dead Thursday in the basement of a townhome.

Someone discovered the bodies at a complex on Akron's northeast side, according to Akron Metropolitan Housing Authority executive director Tony O'Leary. He said police told his office no weapons were found in the home.

Police said that two men and two women who appeared to be in their 20s had been shot in their heads, but they didn't release any other details. It was unclear whether police were looking for any suspects.

At the housing complex, about 35 miles south of Cleveland, crime scene tape cordoned off one area as officers canvassed for information about what happened.

The units, in an older, small complex near a mall, are normally quiet and don't have a history of crime, O'Leary said.

"It's certainly not what some people see as a typical public housing unit," he said.
