"I feel disgusted about the whole case," she said then. "I lost my son, my grandchildren lost their father. No one thinks about all the tragic things that we are going through and then they are making a circus about someone who is guilty as can be."
Seven witnesses have since changed their testimony. Darrell Collins, a friend of Davis', said in an affidavit that he initially denied that Davis was involved in the murder, but "after a couple hours of the detectives yelling at me and threatening me, I finally broke down and told them what they wanted to hear. They would tell me things that they said had happened and I would repeat whatever they said."
Another witness said she was on parole and feared she would be sent back to prison if she did not tell police that Davis killed MacPhail.
"We need to have a day in court where a judge hears the evidence and explanation showing why that person likely did testify falsely," Ewart has told ABC News.
