And they've found a shallow grave.
The bodies were found on the city's southeast side in a building on East 122 and Imperial.
Sex crimes investigators were serving a search warrant on 50-year old registered sex offender Anthony Sowell.
Sowell's suspected of strangling a woman with an extension cord until she lost consciousness. He even threatened to kill her.
A SWAT unit entered and found the decomposed bodies on the 3rd floor.
They also found what appears to be a freshly dug shallow grave in the basement.
Sowell is still on the run and a person of interest in several other unsolved crimes.
He spent 15 years in an Ohio penitentiary in 1989 for Rape.
He wears eyeglasses and frequently wears a mustache and occasionally a beard. He is known to walk the streets "scrapping" and frequents area scrap metal yards.
