Answer:
DNA evidence that does not match Ronald.
Step-by-step explanation:
DNA evidence is the most reliable. it does not rely on the interpretation of man, but instead the work of science.
Ronald recanting his confession is wrong, because he already gave a confession and reciting it twenty years doesn't change the fact that he already confessed to it.
New witness information is wrong, because a new witness twenty years later is not trusted or reliable. It is harder to confirm whether they were at the scene or not.
A negative polygraph test is wrong, because are inadmissible in court since they cannot definitively detect when someone is lying, but truly just detect physical changes that could be triggered by a multitude of emotions.
