The execution came 20 years after Davis was convicted of the murder of Mark Macphail, a 27-year-old police officer who was shot and wounded after intervening in a fight outside the store. The case has been in and out of court ever since, as increasing doubts were cast on his conviction.
There was no physical evidence, blood samples, or DNA linking Davis to the crime. The murder weapon was never found. His conviction instead relied on witness statements from nine people, seven of whom have since recanted their evidence, saying they were coerced into delivering it by police officers.
Several members of the jury have since come forward to say that they reached the wrong verdict. Meanwhile, a further witness has claimed that another man, Sylvester Coles, privately confessed to the murder.
