The Blade of Toledo reports attorneys for 59-year-old Nathaniel Cook are expected to file for his judicial release as early as this week under terms of his plea agreement.
Cook pleaded guilty to attempted murder and two counts of kidnapping, for a 20-year sentence that ends Tuesday.
Prosecutors say Cook was with his older brother and helped him with three of the nine killings. Anthony Cook is serving two life terms in prison.
The Lucas County prosecutor's office wants Nathaniel Cook to be evaluated for a possible designation as a sexual predator so he'll be forced to register his address.
This story has been corrected to show that Nathaniel Cook admitted taking part in three slayings, not nine of the killings.
