America’s Crime Lab – “Crimes in Two Cities: The Sumpter Siblings Cold Case”
Podcast: America’s Crime Lab
Episode Date: October 1, 2025
Host: Alin Letzlesser
Producer/Co-Host: Katherine Fenollosa
Featured Guest: Shannon Hodder (Senior Assistant District Attorney, DeKalb County, Georgia)
Overview
This episode centers on the 1990 murders of siblings Pamela and John Sumpter in Stone Mountain, Georgia—a brutal cold case left unsolved for over thirty years. The show explores how evidence from the crime scene, particularly a decades-old rape kit, eventually intersected with modern forensic DNA technology and cross-state investigation to finally identify and convict their killer, Kenneth Perry. The episode highlights the challenges of cold case work, improvements in forensic science, and the emotional impact on victims' families.
Key Discussion Points & Insights
The Sumpter Siblings Crime Scene (02:13 – 08:19)
-
Initial Incident: On July 15, 1990, Pamela Sumpter staggered wounded to a neighbor’s doorstep, covered in blood, stating she’d been stabbed and raped. Police responding discovered her brother John Sumpter murdered in their shared apartment.
- Pamela's Statement: Before surgery, Pamela described her attacker as an unknown, muscular, dark-skinned man, possibly called "Al" or "Eddie," whom her brother had brought home. (03:28 – 04:49)
-
Events Leading Up To Crime:
- John and the suspect went out clubbing; Pamela declined to join and went to bed. She woke to find the man naked and armed with a knife in her bedroom before being attacked.
- Pamela underwent emergency surgery but succumbed to her injuries two weeks later, never regaining consciousness after initial interviews. (08:04 – 09:24)
“She says the guy’s name was maybe Al or Eddie. She can’t really remember… He was dark-skinned and he was built like a bodybuilder.”
—Katherine Fenollosa [05:17]
The Investigation and Evidence (09:28 – 12:20)
-
Crime Scene Details:
- Police meticulously collected evidence: fingerprints from plates and doorknobs, a suspected murder weapon, and biological samples including Pamela’s rape kit. The phone lines had been cut, and the apartment was in disarray.
- “They were able to collect the knife that was near John’s body that was the suspected murder weapon.” —Shannon Hodder [11:16]
- Police meticulously collected evidence: fingerprints from plates and doorknobs, a suspected murder weapon, and biological samples including Pamela’s rape kit. The phone lines had been cut, and the apartment was in disarray.
-
Forensic Limits (1990):
- DNA databases like CODIS weren't widely available; at the time, DNA evidence could only be compared directly if police had a specific suspect.
Decades of Frustration & The Unsolved Case (12:20 – 19:18)
- Case Goes Cold:
- With no viable leads, the case stagnated, and the collected rape kit went untested for decades.
- “Without any tips or leads coming in, the case wasn’t really ever looked back at again.” —Shannon Hodder [18:56]
DNA Backlogs & The Turnaround (19:28 – 21:29)
-
Federal Push for Testing:
- In 2022, a federal initiative funded the testing of backlogged rape kits (Sexual Assault Kit Initiative). The DeKalb County DA’s cold case task force began reviewing cases, focusing on those (like Pamela’s) likely to have useful DNA evidence.
- “I believe the GBI sent off over 700 rape kits, and Pamela Sumpter’s case was one of the ones that really stuck out to us.” —Shannon Hodder [20:22]
-
The Rape Kit Is Tested:
- Pamela’s kit returned a male DNA profile (from semen) — but at first, there was no match in state or national criminal databases.
- “We had no hits whatsoever.” —Shannon Hodder [22:08]
Breakthrough via Genetic Genealogy (22:27 – 32:47)
-
Cold Case Strategies:
- DA Shannon Hodder saw the chance to use forensic genetic genealogy, building family trees from DNA to tease out suspects when criminal databases fail.
-
Unexpected Match:
- While uploading the DNA profile into CODIS, it matched not a person—but an unsolved 1990s Michigan sexual assault case.
- Michigan police had questioned someone (Kenneth Perry) in that case and collected his DNA but did not prosecute. Now, with the match, investigators had both a name and a potential link.
- “They had to go back to their archives. They told us ahead of time, listen, manage your expectations. We had a huge flood in our archives...” —Shannon Hodder [24:10]
- After two weeks, Michigan’s file with Perry’s identity was miraculously found intact.
- While uploading the DNA profile into CODIS, it matched not a person—but an unsolved 1990s Michigan sexual assault case.
“I believe the GBI sent off over 700 rape kits, and Pamela Sumpter’s case was one of the ones that really stuck out to us.”
—Shannon Hodder [20:22]
- Genealogy and Evidence Converge:
- Othram Lab built a criminal profile using genealogy, confirming the DNA belonged to Kenneth Perry’s family tree.
- Perry’s fingerprints were matched to those found at the Sumpters’ apartment.
Arrest and Conviction (31:53 – 34:45)
-
Arrest:
- A stakeout led to Perry’s arrest at a restaurant; police confirmed his identity with a DNA swab.
-
Court Case:
- At trial, Perry testified with “one of the most outrageous, disgusting stories I’ve ever heard as a prosecutor,” falsely accusing the victims of assaulting him.
- “He tried to flip the script and turn the Sumters into his attackers.” —Shannon Hodder [32:49]
- At trial, Perry testified with “one of the most outrageous, disgusting stories I’ve ever heard as a prosecutor,” falsely accusing the victims of assaulting him.
-
Justice and Family Impact:
- Perry received three consecutive life terms plus 100 years. Shannon Hodder delivered the news, in person, to Pamela and John’s mother—just weeks before her 100th birthday.
- “She honestly said she could only believe that it was the work of God, it was the hand of God delivering justice to her to make sure that she saw the person responsible convicted and tried and held accountable...” —Shannon Hodder [34:20]
- Perry received three consecutive life terms plus 100 years. Shannon Hodder delivered the news, in person, to Pamela and John’s mother—just weeks before her 100th birthday.
Reflections on Cold Case Work and DNA Technology (34:45 – 37:34)
-
Unresolved Motive:
- The precise motive or backstory linking Perry to the Sumpters remains unknown. But the episode emphasizes the healing power of closure.
-
Broader Lessons and Hope:
- The hosts and guests reflect on how new genetic technology can prevent serial offending if used early.
- “To live in a world where perpetrators are caught the first time… to prevent that second and third and fourth and fifth attack, especially in sexual crime, where they’re repetitive…”
—Alin Letzlesser [36:02]
-
The Emotional Cost of Cold Case Work:
- Shannon Hodder describes the rollercoaster of cold case work, where decades-old evidence is often lost or destroyed, but in rare cases like this, everything aligns.
