Cold Justice season 8 returns to Florida for Deadly Message, a re-examination of the 1999 shooting of Stephanie Jackson, a churchgoing mother and grandmother found dead in her Gifford home. Investigators reopen the file with a simple question that reshapes the case: was the target the woman in the chair, or someone close to her?
The episode was released on October 11. Kelly Siegler and Abbey Abbondandolo collaborate with Indian River County detectives and retired cold case investigator Nancy McNally to reexamine old facts, incorporate new forensic evidence, and identify a single detail that suggests motive and intent.
Background and setup in Cold Justice season 8
On the morning of Sept 3, 1999, Jackson was discovered sitting in a living room chair with a pillow over her face and three gunshot wounds to the head. There were no signs of forced entry. Two purses were knocked to the kitchen floor. Cash remained. One item was missing.
According to Oxygen, the door was locked from the outside with a simple push-button handle as the killer left, a move made out of habit rather than a burglar’s.

The team also reviews renewed forensic work. TCPalm reported that retesting with newer DNA methods produced material not detected before and that investigators believe the suspect is someone close to the family.
The key detail in Cold Justice season 8 that signals a message
The key detail is the theft of a single driver’s license belonging to Jackson’s adult daughter, taken while cash sat untouched. The ID was the only thing removed from the house and was later found discarded along a nearby roadway. That choice reads less like theft and more like pointed communication.
Nothing else in the scene aligns with a profit-motivated crime. With money left behind and no forced entry, the selective removal of the daughter’s ID stands out as the act that, reportedly, turns the murder into a warning.

Why that detail in Cold Justice season 8 points away from a random burglary
A random intruder would take valuables and escape quickly. But here the intruder took time to rifle purses, ignore $187, and leave with an identifier tied to a specific person. Investigators in the episode describe the ID theft as “sending a signal,” a pointed act aimed at someone living in the home, not at the victim’s bank account.
Another small scene fact supports a familiar hand. The locked door on exit suggests a resident’s habit with that older knob. According to Oxygen, the push-button lock can be set and pulled shut with no extra effort, which fits daily muscle memory more than an unknown prowler’s thinking.
What Cold Justice season 8 build around the “message” clue
The case file includes friction in the daughter’s life at the time. Local reporting describes a difficult divorce and past threats that, allegedly, raised safety concerns. CBS12 noted that the sheriff’s office has long referenced a solid suspect and renewed its plea for tips, while the episode shows the team seeking prosecutorial review of the findings. The “message” theory aligns with that focus on someone with a personal tie, not a stranger passing through.
The ID theft also fits the staging. A pillow over the face points to a personal setting. TCPalm quoted a sheriff’s official explaining that such covering often tracks to familiarity. While any single clue can mislead, the cluster here — locked door, no forced entry, cash left behind, only the daughter’s license taken — points the same way.
The timeline is tight. School drop-off, a short gap, discovery. Witness and records work placed Jeffrey Swanigan in the area that morning, according to Press Journal archives, and the episode shows the team weighing those sightings against the physical scene. The alleged motive discussed on air centers on hurting a loved one by harming the person she loved most.

The Cold Justice episode keeps circling back to the ID. That lone item links the violence to a specific recipient of the message. A killer trying to taunt or warn the daughter would know to take something that carries her name and photo, then drop it where it would be found nearby.
New episodes of Cold Justice season 8 air Saturdays at 8 pm on Oxygen. The show can also be streamed on Peacock and the Oxygen app.
