All of Taylor's appeals have been unsuccessful.
The head of the commission began Thursday's hearing by saying the physical evidence in the trial was missing 16 years ago.
A former prostitute testified that she saw Taylor in an SUV and the victim was outside his driver's side window. But there are problems with the case.
An investigator for the commission said the former prostitute's testimony is inconsistent with past stories.
Also, a substance thought to be blood on Taylor's truck was never tested for blood. His DNA did not match any DNA found on the victim.
The hearing is scheduled to wrap up Friday.
The General Assembly created the Innocence Inquiry Commission in 2006 with the purpose of investigating imprisoned convicts who claim innocence.
Taylor's case is the third one to go before the panel.
