Ray Krone was wrongly convicted and sentenced to die because of an expert witness on bite mark evidence. Despite the fact that Ray had an alibi, and that the other evidence at the crime scene did not point to him, the jury was swayed by this so-called expert.
What the jury did not know, however, was that the prosecution paid this expert around $50,000, ten times the total amount Ray had to defend himself. He spent 10 years in prison before his conviction was finally overturned.
