DNA test cleared rape allegation against prison guard

Here's a story of a front-end DNA exoneration I hadn't heard before which occurred in the Texas prison system - a guard falsely accused of raping a female inmate. The anecdote appeared in a recent Marshall Project story on Nigerian guards working in the Texas prison system:

In 2009, a Nigerian officer in Huntsville named Marshall Akpanokop was accused of raping and impregnating a female prisoner. He was later proven innocent when a DNA test revealed that he was not the father, but Akpanokop sued the agency, arguing he had been “singled out as the culprit” because “he was a dark-skinned, Nigerian national with an accent.”
