Corrected entry: Kimble searches records of people who have had prosthetic arms installed, which is how he eventually finds Frederick Sykes. Kimble and his lawyers should have been given access to those records prior to his trial, and if so, there's a good chance they would have found a record of Frederick Sykes.

Correction: It's unlikely that Kimble was allowed to just browse a medical database and meet the resulting names face to face back while he was on trial. It would have been the police following up on Kimble's claims of a one armed perp, but they already didn't believe Kimble was telling the truth, so they wouldn't have pursued it the way Kimble would have wanted. Plus, Sykes himself mentioned that he was questioned about the murder a year ago, but he had an alibi. It was only after a determined Kimble broke into his house and violated due process that they were able to actually begin to get evidence.

Yes, but Kimble gave his car to Nicholls on the night of the murder, and there was a phone call placed from Kimble's car phone to Sykes. Also, why would Kimble, who was a doctor and very smart, make up such a bizarre story about a one-armed man killing his wife?
