(CNN) -- Investigators discovered four more bodies Tuesday at the Cleveland, Ohio, home of a convicted rapist -- making a total of 10 since last week, Police Chief Michael McGrath said Tuesday.
Authorities on Tuesday charged Anthony Sowell with five counts of aggravated murder after unearthing the bodies of women at his home last week, police said.
Sowell, 50, also was charged with rape, felonious assault and kidnapping, police said. His arraignment is scheduled for Wednesday morning.
Police arrested Sowell on Saturday, two days after discovering the decomposing bodies of five females inside his home and another woman's body outside the house.
Earlier Tuesday, a source close to the investigation had told CNN that a seventh body had been found in the home. The source, who was not authorized to speak on the record, did not reveal the gender of the seventh body found at Sowell's home. The source did not say exactly where the body was found at the residence.
Authorities found the first two bodies last week while trying to serve an arrest and search warrant on Sowell related to a sexual assault investigation, and an intensive search began. Sowell was not home at the time; officers found him after a tipster told them of his whereabouts.
The decomposing bodies of the first six women, all of whom were African-American, could have been lying where they were found for "weeks, if not months or years," Cuyahoga County Coroner Frank Miller III told CNN on Saturday
