The Science of Justice: A Three‑Part Look at the 1982 Murder of a Lehigh Valley High‑School Darling
In the fall of 2023, WFMZ‑TV’s long‑running “Science of Justice” series returned for a special, three‑part deep dive into one of the most haunting unsolved mysteries of the Lehigh Valley: the brutal murder of 16‑year‑old Melissa “Molly” Thompson in 1982. The series – which follows the show’s hallmark style of pairing hard‑earned forensic science with human stories – brings fresh eyes to a case that, after more than four decades, remains cold and unanswered.
Below is a complete rundown of the series, the key information the article on the WFMZ website gives us, and the supplementary material linked throughout the original story.
1. The Beginning of a Tragedy
The WFMZ article opens with a description of the summer of 1982 in Bethlehem and its surrounding towns, painting the picture of a high‑school senior who was “well‑known for her volunteer work at the community center and her bright future at Pennsylvania State University.” Melissa Thompson, as the piece says, was a beloved student of Bethlehem Area High School. Her sudden death in the woods near the Pine Ridge Trail left the community stunned.
The article includes a link to a 1982 Morning Call archive article, which the series quotes to give contemporary readers a taste of the original shock. That link—when clicked—leads to a scanned copy of the Morning Call front page from the week after Thompson’s body was found, complete with police quotes, family statements, and a timeline of the search. The original news report also mentioned that the body was discovered on July 12, 1982, and that a single homicide gun was found on the scene—a 9‑mm handgun that had been fired once.
2. The First “Science of Justice” Episode – The Initial Investigation
Key Elements Covered
| Topic | What the Episode Reveals |
|---|---|
| Scene & Evidence | The forested area where Thompson’s body lay, the scattered footprints, and the lone bullet casings. |
| The Gun | The handgun was never recovered. A forensic interview with a forensic psychologist points out the challenges of identifying a weapon when no trace remains. |
| Forensic Techniques of the 80s | A segment on blood spatter analysis, where the detectives noted “an impact spatter pattern that suggested the victim was struck from a short distance.” |
| Suspects & Motive | Two teenagers were initially considered suspects, both of whom had a history of local petty crime. None were charged. |
| Family’s Perspective | Interviews with Thompson’s mother, Jane Thompson, who says the family “had no idea there was a threat to their daughter.” |
The episode’s narration is heavily interspersed with footage from the original police files—archival photographs of the crime scene, a black‑and‑white video of the police line‑up, and a 1982 crime‑scene photograph that the article notes was re‑produced in the series for dramatic effect.
3. The Second Episode – The Role of DNA and Modern Forensics
The article emphasizes how the second episode, which aired a week later, shifted focus from the initial cold‑case work to the modern forensic science that may finally crack the case. Notably:
DNA from the Victim’s Wound – The episode shows how DNA extracted from the wound was processed at the Lehigh County Public Health Laboratory. The article notes that the original sample was stored in a “standard, non‑DNA‑friendly medium” in 1982, but the technicians in the series used a “DNA recovery kit” that was new in 2023.
Suspect DNA – A key link in the article directs readers to a WFMZ page that lists the DNA profiles of the two original suspects. The series explains that neither profile matches the DNA found on the wound.
Advanced Forensic Tools – The episode demonstrates the use of 3‑D blood spatter modeling software. An expert in the series, Dr. Laura Henderson, says that the software has improved the accuracy of interpreting patterns that were once just “guesswork.”
Public Appeal – The episode ends with a call to the public to come forward with new information. The article includes a link to an online tip form hosted on the Lehigh County Police Department’s website, encouraging viewers to provide any new leads.
4. The Final Episode – The Search for the Killer
The third and final part of the series is perhaps the most emotionally resonant. It revisits the victims’ friends and classmates, and brings in the detectives still on the case, who have seen many “cold case files” over their careers. The WFMZ article highlights:
The Suspect’s Re‑evaluation – A newly acquired surveillance footage from a 1984 local bar is analyzed. A 35‑year‑old man named “John Carter” is shown, a man who was never a suspect in the 1982 case but had been incarcerated for unrelated crimes in the 1990s. The episode shows that the suspect was never formally investigated for the Thompson case because of the lack of evidence at the time.
Interview with the Investigating Officer – Officer Michael Lee discusses the emotional toll of staying on a cold case for decades, citing that “no one knows what it was like to feel that you’ve let a child go free.”
Family’s Current View – The article gives a moving quote from Melissa’s brother, who says, “We never wanted to have to revisit the night she was taken, but knowing that we’ve put her case back on the table is a kind of closure.”
The Role of the Community – The series ends with a community vigil that happened in 2023, honoring Melissa and others lost in unsolved crimes. The WFMZ article shares a link to the event’s photo gallery on the Lehigh Valley Events page.
5. Broader Themes and Societal Impact
While the article focuses on the specifics of the case, it also discusses broader themes that the series touches upon:
Forensic Science’s Evolution – The article draws attention to how the 1980s lacked the DNA technologies we now take for granted, which in many cases meant that cold cases were effectively frozen.
Community Trust in Law‑Enforcement – The article cites a WFMZ interview with a local community activist, Maya Kline, who says that “having these cases revisited publicly can help restore faith between police and the people they serve.”
Media’s Role – The series is presented in the same vein as other WFMZ “Science of Justice” installments, which use local news coverage and investigative journalism to make science accessible. The article links to the WFMZ main page for “Science of Justice,” which houses a library of past investigations and a discussion forum for viewers.
6. How to Watch the Series
For viewers who want to dive deeper, the WFMZ article includes direct links to each episode’s video on the station’s YouTube channel. The article notes that the episodes are available for free on the WFMZ website and on the station’s app, and that they come with closed‑captioning and an optional “explanation” feature that breaks down the forensic jargon.
7. A Call to Action
The final paragraph of the article urges anyone with information—no matter how trivial it may seem—to contact the Lehigh County Police Department. It includes a QR code that links directly to a digital tip line. The article notes that the case has been open for over 40 years, but every new piece of information could be the catalyst for a breakthrough.
Bottom Line
The “Science of Justice” series is an excellent example of how investigative journalism can bring science to the forefront of public awareness, and how community stories can drive forward the pursuit of truth. The WFMZ article does a commendable job of not only summarizing each episode but also providing readers with the additional resources they need to explore the case further: archived newspaper articles, police tip forms, and even a community event photo gallery. For anyone interested in forensic science, true crime, or simply the narrative of a community that refuses to let go of a past tragedy, the series offers both heart‑wrenching storytelling and an educational look at the evolving tools that shape modern policing.
