The Secret
Episode of 48 Hours · May 27, 2026 · 41 min
Correspondent Tracy Smith reports on the 2007 disappearance of Georgia 911 dispatcher Teresa Parker and the no-body murder trial of her police-officer husband, Sam Parker.
Summary
This classic 48 Hours episode, reported by Tracy Smith, followed the March 2007 disappearance of Teresa Parker, a Walker County, Georgia 911 dispatcher who was divorcing her husband, Lafayette police officer Sam Parker. Her sister Christina Hall and coworker Rhonda Knox described growing alarm, and Sheriff Steve Wilson called in the Georgia Bureau of Investigation because of his personal ties to the couple.
GBI agent James Harris and FBI agent Mark Veazey described inconsistencies in Parker's timeline, phone calls he denied making, tracking-dog alerts, and Teresa's blood and Parker's DNA in her vacuumed SUV. Parker was charged nearly a year later. He denied killing her and suggested she had gone to Mexico; his brother Kenneth Parker defended him, while Christina Hall and ex-wife Keela Beard described drunken violence and threats that he knew how to hide a body.
At trial, prosecutor Lee Patterson argued Parker killed Teresa, possibly with a chokehold, then went on a date for an alibi before disposing of her body. Defense attorney David Dunn called the case character assassination and attacked witness Ben Chafin, who testified to a phone confession but had given five stories. Jurors, initially split, focused on cell phone records and convicted Parker of murder on September 3, 2009; he received life in prison. An epilogue noted Teresa's skeletal remains were later found in Chattooga County and her death ruled a homicide.

Key points
What was said, by whom, with the exact words. Timestamps jump to the moment.
- James Harris
Harris says Parker's claim that he was in his truck all night contradicted witnesses and made him a suspect.
“So then that's when red flags started going up and Sam became a suspect in my eyes”
- James Harris
Harris says Parker had told many people he knew how to dispose of a body so no one would find it.
“He told everybody in Walker County but a couple that he knew how to get rid of a body. No one would ever find it”

“The back of the 4Runner had been obviously vacuumed. You could see the vacuum marks”
- David Dunn
Dunn argued there was no forensic evidence showing Teresa had been killed.
“Nobody knows that she was killed. There's no physical, there's no forensic evidence. There's nothing to show that she was killed”
- Lee Patterson
Patterson says cell tower data showed Shane Green was not in Gatlinburg, rebutting the defense's boyfriend theory.
“the cell phone towers show that his cell phone activity was not in Gatlinburg”

“Oh, he's probably the most unbelievable witness I've seen in 26 years of practicing law”
