DDC: DNA Test Sets Inmate Free After 18 Years

DNA Diagnostics Center’s Forensics Division provided the DNA testing that eventually resulted in the release of inmate Robert McClendon. McClendon had spent 18 years in prison, convicted of a child rape that he has always maintained he did not commit.

McClendon’s is 1 of 30 cases in Ohio that were identified to have “legitimate claims of innocence” in an investigation conducted by The Columbus Dispatch together with the Ohio Innocence Project (OIP). DDC has volunteered to provide DNA testing for the OIP's post-conviction cases free of charge.

DNA Testing Holds Promise of Justice

A 5-day series in The Columbus Dispatch published in January examined Ohio’s criminal justice system and its ability to use DNA evidence for possible exoneration of wrongfully convicted inmates. With the help of The Ohio Innocence Project, The Dispatch’s yearlong investigation resulted in a list of 30 cases that it considered prime for DNA testing. DDC is pleased to announce that it will provide the appropriate DNA testing for these inmates in the interest of justice.
