Cory Martin's murder of Brandy Odom is one of the most calculated true crime cases we've covered. He spent a year planning—taking out $200,000 in life insurance and studying Dexter daily to learn how to kill.

Built from 2,977 pages of federal court documents and trial testimony, this episode reveals how digital forensics and a co-conspirator's confession finally brought justice after the case went cold for two years.

Martin is now serving life in federal prison. Court documents are sent exclusively to subscribers when episodes drop — subscribe now at https://truecrimeunheard.com/subscribe so you don't miss future case files.
