(CLEVELAND) -- Cleveland prosecutors say the three women who were kidnapped, tortured and held captive for years by Ariel Castro kept diaries of their ordeal.
The revelation is in a released memorandum that prosecutors say they will use at Castro’s sentencing Thursday to convince a judge that he should be given the prison sentence he agreed to in a plea deal: Life plus 1,000 years.
The memorandum provides additional shocking details of Amanda Berry, Gina DeJesus and Michelle Knight’s time in captivity.
The women were abducted between 2002 and 2004 when they were 14 to 20 years old. They were rescued in May.
Prosecutors say their ordeal included the use of chains, access to only plastic toilets in the bedrooms which were rarely emptied, and the use of the "cold of the basement" and "heat of the attic" as punishments.
Prosecutors say Castro once kept the women locked in a vehicle for three days while he had a visitor.
Authorities tell The Cleveland Plain Dealer that at least one of the women -- and possibly all three -- is expected to speak at Castro’s sentencing hearing.
Castro, 53, pleaded guilty to 937 counts of a 977-count indictment in a plea deal last week that is expected to put him behind bars for life without parole, plus 1,000 years.
In addition to statements from the victims, Castro will be given the opportunity to speak at Thursday’s hearing.
