Without retrying the case here and just going off of the verdict & juror comments -
The jury obviously disregarded Wayne's testimony. The State never actually proved Jimmy was ever inside the house. It was pretty clear to me that the jury felt the conspirators were Mark & Wayne, hence his acquittal on the conspiracy charge. Per at least one juror, the primary evidence that convicted JR was the disposal of the jumpsuit and his phone.
If I was the defense and had this info, I would have argued that Wayne and Mark had yet another motive to murder Teresa. They were going to be charged with fraud. Jimmy was clueless when it came to the Medicare fraud, why would he want her dead? IDK if it would change the verdict but I don't think the jury found Wayne credible at all. I just think this would have been another reason for them to believe Wayne committed the act, as opposed to JR.
