Joseph Sledge Jr. (born 1942) is an American man who was convicted of the murders of two women, Josephine and Aileen Davis, for which he was imprisoned for over 36 years before being exonerated by new DNA evidence.
 His case represents the longest duration of incarceration for a case that has been overturned by DNA evidence, and he is the longest-serving inmate to have been exonerated in North Carolina.
Satish C. Sekar (born September 1963) is a British author and journalist, and a consultant in forensic evidence.
 Sekar has specialised since the 1990s in the investigation of miscarriages of justice.
 His work has been published in newspapers including "The Guardian", "The Independent" and "Private Eye", and he has also worked for television documentaries including "Panorama" and "Trial And Error".
 He has worked on a number of high-profile cases in the UK including the Cardiff Newsagent Three, Gary Mills and Tony Poole (wrongly convicted in 1990 for the murder of Hensley Wiltshire), the M25 Three, and Michelle and Lisa Taylor (wrongly convicted in 1992 for the murder of Alison Shaughnessy).
 He also worked on the case of the Merthyr Tydfil Two (Donna Clarke and Annette Hewins), presenting scientific findings to South Wales Police regarding the fire that resulted in the police's expert accepting his conclusions that the petrol bought by Hewins that night was not the petrol used in the fatal fire.
 In 1992, his work helped overturn the convictions of the Cardiff Three and while researching a book about the case, "Fitted In: The Cardiff 3 and the Lynette White Inquiry", he uncovered errors in the original evaluation of forensic evidence from the crime scene.
 His submissions to the Home Office about the DNA evidence were instrumental in reopening the case and the eventual extraction of a DNA profile which led to the arrest and conviction of the real killer, Jeffrey Gafoor, in 2003.
 The "Australian and New Zealand Journal of Criminology" said that Sekar's "extraordinary work on the case of the Cardiff 3 [put] academic criminology to shame."
Tina Marie Harmon (born June 9, 1969 – October 29, 1981) was a 12-year-old American girl who was abducted, raped and murdered on October 29, 1981 after being dropped off in Lodi, Ohio.
 After the discovery of her body, she was later buried at the Maple Mound Cemetery.
 One man was originally convicted of the victim's murder on circumstantial evidence but was eventually released when the conviction was overturned.
 Harmon's murder was solved in 2010 when DNA from the individual who raped her was matched to Robert Anthony Buell.
Robert Anthony Buell (September 10, 1940 – September 24, 2002) was a former Akron, Ohio Planning Department worker, convicted of the murder of 11-year-old Krista Lea Harrison on July 17, 1982.
Gary Dotson is an American man who was the first person to be exonerated of a criminal conviction by DNA evidence.
 In May 1979, he was found guilty and sentenced to 25 to 50 years' imprisonment for rape, and another 25 to 50 years for aggravated kidnapping, the terms to be served concurrently.
 This conviction was upheld by the appellate court in 1981.
 In 1985, the accusing witness recanted her testimony, which had been the main evidence against Dotson.
 He was not exonerated or pardoned at that time, but due to popular belief that he was a victim of a false rape accusation, Dotson went through a series of paroles and re-incarcerations until DNA evidence proved his innocence in 1988.
 Dotson was subsequently cleared of his conviction.
The murder of Krista Lea Harrison occurred on July 17, 1982, in Marshallville, Ohio.
 The case remained unsolved for two years, until Robert Anthony Buell was convicted of her murder in 1984.
 Harrison's case appeared on the fifth season of the American television show "Forensic Files" in an episode titled "Material Evidence."
Recorded Live: The 12 Year Old Genius is the first live album by Stevie Wonder.
 The album was released on the Tamla record label (catalog #240) in May 1963, the same month as the single release of "Fingertips" (catalog #54080).
 "Fingertips" topped both the "Billboard" Hot 100 chart and the R&B Singles chart, and "Recorded Live: The 12 Year Old Genius" topped the "Billboard" 200, all of which happened in 1963.
 This is the last album to use the "Little" in Stevie Wonder's name.
 Starting with the next album, his name goes by just "Stevie Wonder."
The murder of Kelly Ann Tinyes occurred on March 3, 1989.
 Tinyes was a thirteen-year-old Valley Stream, New York resident who was strangled, stabbed, and mutilated.
 Her body was discovered in the basement of her neighbor, twenty-one-year-old bodybuilder Robert Golub, who was charged and convicted of her murder.
 Golub was convicted based on DNA evidence that showed that he matched the genetic markers found in a blood sample discovered on evidence.
 The trial was the first case in New York state to have a case won by DNA forensic evidence.
The murder of Eric Morse occurred on the evening of October 13, 1994 in the Ida B. Wells Homes housing project on the south side of Chicago, Illinois.
 The killing was particularly notable for the young ages of the victim (5 years old) and the killers (10 and 11, respectively).
 Morse's murder drew national attention to the plight of children in Chicago's housing projects.
 The event occurred only a month after 11 year old Robert Sandifer fatally shot a 14 year old girl, and was then murdered by his fellow gang members.
