CLEVELAND - The man suspected of kidnapping three women in Cleveland and holding them in captivity at his home for years calls himself a sex addict, a source close to the investigation said.
According to the source, Ariel Castro, 52, is quiet and cooperating with investigators. At some point since his arrest Monday, he told them he has a sex addiction.
Castro is also in "administrative segregation" at the Cuyahoga County Jail, which means he's in a cell by himself and has not come in contact with other inmates in the jail, the source told Scripps station WEWS. A sheriff's deputy has also been assigned to monitor Castro around the clock.
As a part of his incarceration, he's under "suicide prevention" due to the high-profile aspect of the case. However, the source said he was deems "not suicidal" when he was evaluated by a medical team at the jail.
The source said among the hundreds of items seized during the investigation, there is a note written by Castro in either 2004 or 2005. In the note, Castro said he is remorseful for what he has done and claims to be a sex addict.
According to a report from CNN's Martin Savidge, a high-ranking law enforcement official said the note was suicidal in nature and Castro included information about previous abuse against him by another family member.
Castrol is charged with rape and kidnapping for allegedly holding Amanda Berry, Gina DeJesus and Michelle Knight in his Seymour Avenue home for years. Berry was able to signal a neighbor for help Monday night – and then called 911.
On Thursday, a judge set his bond at $8 million -- $2 million for each charge.
