Sebesta had convicted Robert Carter for the murders and tried to get Carter to say Graves was an accomplice. However, just a day before the trial, Carter told Sebesta he acted alone and Graves was not involved. Sebesta withheld the information from the defense and presented false testimony implicating Graves. Sebesta also blocked an alibi witness by telling the court that the witness was a suspect in the murders and could be indicted. The witness then refused to testify.
After his conviction was reversed, a special prosecutor found in 2010 that there was no credible evidence that Graves was involved in the murders.
