A respected veterinarian is found dead under mysterious circumstances in an upscale Rancho Santa Fe neighborhood. What first looked like a car accident quickly turned into a homicide investigation filled with unanswered questions — a wrecked vehicle, blunt-force trauma, and no clear explanation of how Dr. Robert Stonebreaker ended up in a nearby driveway. Nearly 15 years later, the case remains unsolved. In this episode, we break down the timeline, the forensic inconsistencies, and the theories that still surround his death.

Jane Mixer
In this episode, we revisit the shocking murder of 23-year-old law student Jane Mixer, long believed to be a victim of Michigan’s “Co-Ed Killer.” When modern DNA testing finally pointed to an unexpected suspect, Gary Leiterman, the case was reopened, re-examined, and fiercely debated.
Was the forensic evidence clear-cut? Or did lab contamination muddy the truth?

Peggy Carr
When 41-year-old Peggy Carr suddenly fell gravely ill, doctors were stumped. Her symptoms made no sense—burning limbs, hair loss, and paralysis with no clear cause. But when her teenage son and stepson became sick too, investigators uncovered a chilling truth: the Carr family had been poisoned.
The substance was thallium—a deadly, nearly undetectable metal once used in rat poison. The discovery launched a full-scale forensic investigation that led detectives to a single suspect: a brilliant but disturbed neighbor with a background in chemistry and a fascination with murder.
This is the story of how science, persistence, and an undercover operation exposed one of Florida’s most shocking poison cases.

Robert Duboise
In 1983, 19-year-old Barbara Grams was found murdered behind a dental office in Tampa, Florida. Detectives said a small mark on her cheek was a bite — and that 18-year-old Robert DuBoise’s teeth matched it. That single piece of forensic “evidence” sent him to death row.
But nearly four decades later, new DNA testing proved what Robert had said all along — he was innocent. The mark wasn’t even a bite.
This week on Forensic Tales, we uncover how junk science, unreliable witnesses, and a discredited forensic method stole 37 years of an innocent man’s life.
Because in forensic science, the smallest mistake can destroy a life.

Jodine Serrin
It was Valentine’s Day, 2007, when 39-year-old Jodine Serrin’s parents stopped by her Carlsbad, California condo to check on her. Moments after walking into her bedroom, they realized something was terribly wrong. Jodine had been brutally attacked—and the man they’d seen inside her home had vanished.
For over a decade, her murder went unsolved. No witnesses. No leads. Just a single piece of DNA left behind.
In this episode, we examine how cutting-edge forensic technology—and one company’s groundbreaking use of genetic genealogy—finally revealed the truth about who killed Jodine Serrin.
