IDAHO FALLS - A district judge is allowing an appeal of an Idaho man's 1996 conviction for rape and murder to move forward.

Chris Tapp is currently in prison for the rape and murder of 18-year-old Angie Dodge. Tapp was convicted after confessing to the crime. New DNA testing shows that none of Tapp's DNA matches the genetic samples taken from Dodge's body.

According to the Post Register, Tapp's lawyer argues that videos of three polygraph sessions were never turned over to Tapp's defense and that those videos could have convinced a jury Tapp is innocent. The appeal also claims that a fourth polygraph was likely or destroyed.

District Judge Alan Stephens ruled Thursday against Bonneville County prosecutors' objections that Tapp had filed his appeal too late.
