Although it says on screen that the film takes place in Melody, Texas beginning in November 2000, the events depicted actually took place in Hearne, Robertson County, Texas, which did begin in November 2000, and were based on the the case known as Regina Kelly v. John Paschall. Melody, Texas is a fictional town name, created for this film.
The real district attorney, John Pischall, is now a convicted felon and can no longer practice law. Paschall was found guilty of stealing over $200,000 from a dead woman's estate in 2015. He was sentenced to six months in jail, 10 years probation, and must pay restitution.
