Cleveland Wright, 55, makes his way to the church he attends at Resurrection Church of God in Christ on Sunday, August 18, 2013, in Washington, DC. Wright seeks to clear his name after serving more than 27 years in prison now that DNA tests last year exonerated his co-defendant in two similar 1978 murders.

Study shows record number of US exonerations

Updated

A new study shows that a record 87 people were exonerated in 2013. Since 1989, the National Registry of Exonerations has tracked more than 1,300 people who were convicted for a crime and later released based on evidence of innocence. Perjury or false accusation contribute to more than half of U.S. exoneration cases, which are most frequently homicides.
