The death sentence of a Texas prisoner has been overturned after prosecutors withheld evidence that could have aided his defense. Alfred Dewayne Brown was convicted in 2005 for the murder of a Houston police officer in a robbery gone wrong. Brown has always maintained his innocence. His death sentence was nixed after lawyers found records of a phone call he had said he made from his girlfriend’s apartment at the time of the murder. Prosecutors say the phone record was withheld by accident, not intentionally. The case now goes to a lower court, but it’s unclear if prosecutors will retry it.
