Murder convictions overturned or death row inmates released?

Any links/stories where DNA evidence has caused a murder conviction to later be overturned after the person has done time or caused a death row inmate to be cleared? My son needs ideas for a criminal justice report.
Type 'death row DNA' into your search engine. I got over a million hits. There is a good selection of sites with stories and facts about the DNA evidence and releases.
There was the one governor in Ohio who released I think it was 8 females from deathrow to life terms something like 4 hours before his term expired.
