In the past two years at Ohio's Correctional Reception Center, nine inmates have died, three have been slammed to the ground and knocked out, and a 16-year-old on suicide watch was pepper-sprayed and left in his cell for nearly three hours without being decontaminated, state records show. The reception center south of Columbus is where thousands of inmates are assigned security levels before moving to other prisons. The cases come to light after a review of hundreds of pages of records obtained by the USA TODAY Network Ohio through public records requests. The cases illustrate issues with the state-sanctioned violence, substandard medical care, concerns about management of staff and security camera blind spots.
