The Murder of Penny Anderson (Massachusetts)

When a woman was found murdered in her Springfield, Massachusetts apartment during the spring of 1984, it only took a matter of days to zero in on a suspect and secure an arrest. And then at trial, a jury decided Edward Wright was guilty beyond a reasonable doubt. The New England Innocence Project has since taken up his case. So, who really killed Penny Anderson? Was it the man serving a life sentence for her death or someone else?
