CLEVELAND (CBS/AP) As a registered sex offender, Anthony Sowell seemed to do everything right. He checked in regularly with U.S. law-enforcement authorities, who also monitored him by making home visits.
But since Sowell wasn't on parole or probation, they didn't have the right to enter — until Thursday when they had search and arrest warrants after a woman said he had raped her there. That's when they made a gruesome discovery - badly decomposed bodies in the house.
By Sunday, authorities had determined there were six bodies, all of them women, and each was the victim of a violent homicide.
Officers had last visited Sowell at home as part of his sex-offender monitoring on Sept. 22, just hours before the woman reported being raped there.
At least five of the women apparently had been strangled, said Powell Caesar, a spokesman for the Cuyahoga County coroner. Decomposition made it difficult to determine how the sixth died, he said.
The bodies "could have been there anywhere from weeks to months to years," Caesar said.
None of the victims has been identified. Two were black, but the race of the others hadn't been determined, Caesar said.
Sowell, 50, previously spent 15 years in prison for the attempted rape of a 21-year-old woman who was lured to his bedroom in 1989, police said. He was arrested Saturday when officers spotted him walking down the street in his neighborhood.
The first bodies were found Thursday night when police went to arrest Sowell on new charges of rape and felonious assault, but he wasn't home. The woman in that alleged attack said she knew Sowell, and he raped her at the house.
Court records and jail officials had no information about whether Sowell had an attorney. No charges have been filed regarding the bodies.
The three-story house with neat white siding is in a crowded inner-city neighborhood of mostly older houses, some boarded up, and small corner stores. The windows on the third floor, where the first two bodies were found, were wide open Sunday as a slight breeze blew. Some neighbors said a bad smell came from the house several months ago, but they thought then that it might be natural gas.
The gruesome discovery left some in the community concerned about women who hadn't been seen in a long time. Ida Garrett, 72, who walked to church Sunday just one block from Sowell's house, said she was worried that a friend who went missing six months ago might be among the dead.
The friend, 43-year-old Nancy Cobbs, lived one street away from Sowell. She was reported missing in April, and her family told police they fear she is among the victims.
"She seemed to be a very nice, quiet girl," Garrett said. "I've known her since she was a teenager."
Clovice Ramsey, minister at All Nations Deliverance Ministries in nearby Maple Heights, held a "PEACE" sign on a corner within sight of the Sowell house and said the discovery of the bodies had damaged people's trust in law enforcement.
"They don't see the system working for them," Ramsey said. "They are not keeping a watch on him."
Sowell often walked around his neighborhood asking for money and looking for scrap metal to sell, neighbors said.
He returned to the family home in 2005 after his release from prison. The house was owned by two of Sowell's relatives, including a woman — described by neighbors as either Sowell's stepmother or aunt — who maintained it.
Neighbors said the woman moved into a nursing home after Sowell was released from prison. Teresa Hicks, a neighbor, said people feared that she might be dead. Police were looking into her status.
EDITOR'S NOTE: The Associated Press has withdrawn reports referring to Sowell as a "convicted rapist." The AP says that Sowell was only convicted of attempted rape, according to police.
