Angel Hernandez (AKA Eduardo Velasquez) spent thirteen years in prison for a crime he did not commit. On November 23, 1988, a jury convicted Hernandez of assault and battery by means of a dangerous weapon, indecent assault and aggravated rape. His conviction was affirmed on August 12, 1991. Blood typing was the only biological evidence presented at the trial in 1991. This test indicated that Hernandez had the same blood type as the assailant, but it was also stated that approximately eleven percent of the Hispanic population shared this blood type. A motion was filed to gain access to the evidence for DNA testing. In 2001 DNA testing was performed on sperm that had been collected as evidence. The results excluded Hernandez, who was exonerated and released on August 15, 2001. Angel Hernandez was represented by Sam Silverman.
