Janet's Secret | Full Episode

Quick Read

A 1979 cold case murder of 23-year-old Janet Walsh is finally solved decades later through advanced DNA forensics, leading to the conviction of a former lover despite conflicting evidence interpretations.
Janet Walsh's 1979 murder went unsolved for decades, with multiple suspects and no clear evidence.
Advanced DNA forensics in 2010 identified Scott Hopkins, a secret lover, as the killer.
The conviction hinged on the location and concentration of Hopkins' DNA, despite defense claims of prior consensual contact and other unidentified DNA.

Summary

In 1979, 23-year-old Janet Walsh was found murdered in her apartment, strangled with her own bathrobe tie and a bandana. The initial investigation stalled, leaving five suspects: her estranged husband Scott Walsh, a drifter Robert McGra, her boss Ron Sakoszi, an unidentified 'Sketchman,' and a secret lover Scott Hopkins. Decades later, in 2010, a cold case unit re-examined the evidence, discovering significant amounts of semen on the crime scene items. DNA profiling eliminated Scott Walsh, Ron Sakoszi, and Victor Sakoszi (a new suspect). Robert McGra refused to provide DNA voluntarily but was compelled by warrant; his DNA did not match. Scott Hopkins, initially alibied by friends, refused a voluntary DNA sample. Investigators obtained his DNA from a discarded water cup, which matched the crime scene profile. Hopkins was arrested in 2012 and convicted of third-degree murder in 2013, despite his defense arguing the DNA was from prior consensual encounters and other unidentified DNA was present. He was sentenced to 8 to 16 years, maintaining his innocence.
This case highlights the transformative power of forensic DNA technology in solving decades-old cold cases, offering closure to families who have waited years for justice. It also illustrates the complexities of interpreting DNA evidence, especially when consensual sexual activity occurred, and the challenges prosecutors face in proving the timing and context of DNA deposition.

Takeaways

  • Janet Walsh, 23, was found strangled in her Manaka, Pennsylvania apartment on September 1, 1979.
  • Initial investigation identified five suspects: estranged husband Scott Walsh, drifter Robert McGra, boss Ron Sakoszi, 'Sketchman,' and secret lover Scott Hopkins.
  • The case went cold for over 30 years due to lack of witnesses and forensic technology.
  • In 2010, a cold case unit found significant semen on Janet's nightgown, robe tie, and top sheet.
  • DNA profiling eliminated three suspects and identified Scott Hopkins as a match.
  • Hopkins' DNA was collected from a discarded water cup after he refused a voluntary sample.
  • Prosecutors argued the DNA's location and concentration indicated it was deposited during the murder, not a prior encounter.
  • The defense contended the DNA could be from previous consensual sex and was transferred, also noting other unidentified male DNA.
  • Scott Hopkins was convicted of third-degree murder in 2013 and sentenced to 8-16 years, maintaining his innocence.

Insights

1Initial Investigation Limitations

In 1979, police faced a murder scene with no forced entry, suggesting Janet knew her killer. Despite multiple suspects including her estranged husband (who failed a polygraph) and a drifter (whose checkbook was found near the scene and also failed a polygraph), the case quickly went cold due to a lack of witnesses and the absence of advanced forensic technology.

Police officer Andy Gaul stated, 'I have a plot from an old TV show like Murder She Wrote where we have five suspects and I can't put a finger on any of them.' Francesco Keltieri, Janet's brother, recalled being told, 'even if the killer walked into the police station and confessed today, we would not be able to take them to trial because we do not have enough evidence.'

2DNA Breakthrough in Cold Case

Over 30 years later, a Pennsylvania State Police Cold Case Unit re-examined the evidence. In late 2010, a lab tech found significant amounts of semen on the top sheet covering Janet's body, her nightgown, and the robe tie used to bind her wrists. This discovery provided a DNA profile, a game-changer for the investigation.

Cold case detective Rocco Demo stated, 'They had found semen on the top sheet that had covered Janet's body... she says, 'No, we have a lot of it in a lot of locations,' including on the back of Janet's night gown and the robe tie that had bound her wrists.'

3Elimination and Identification of Suspects via DNA

Investigators systematically collected DNA from the initial suspects. Scott Walsh, Ron Sakoszi, and Victor Sakoszi were eliminated. Robert McGra, who had previously failed a polygraph and whose checkbook was found near the crime scene, refused to provide DNA voluntarily but was compelled by warrant; his DNA also did not match. This left Scott Hopkins, a secret lover, as the primary suspect.

Rocco Demo stated, 'First thing I do is get the DNA and eliminate Scott Walsh. Then Ron Sakoszi and DNA eliminates Victor Sakosi.' Andy Gaul confirmed, 'It was not a match' for Robert McGra, leaving 'Scott Hopkins' as the last suspect.

4Covert DNA Collection and Arrest

Scott Hopkins, an influential councilman, refused to voluntarily provide his DNA, claiming it would be present due to prior consensual sex. Investigators devised a plan to collect his DNA covertly by retrieving a discarded water cup he used daily at the Bridgewater Burrow building. The DNA from the cup matched the crime scene profile, leading to an official warrant and his arrest in January 2012.

Andy Gaul described the plan: 'Scott Hopkins was a Bridgewater Councilman. Every day early in the morning, he came into the Bridgewater Burrow building... and took a drink out of a water fountain and would throw his cup away.' The cup was tested, and 'Hopkins was a match to the crime scene DNA profile.'

5Controversial DNA Interpretation and Verdict

At trial, prosecutors argued the '4 plus' concentration and specific 'location, location, location' of Hopkins' DNA on Janet's nightgown, robe tie, and top sheet indicated it was deposited during the murder, not a prior encounter. The defense countered that the DNA could be from past sexual encounters and transferred by perspiration, also noting the presence of other unidentified male DNA and Scott Walsh's sperm on the sheets. Despite the defense's arguments, Hopkins was convicted of third-degree murder.

Prosecutor Britney Smith explained, 'Scott Hopkins seminal fluid is on that location in a concentrated manner and it is not consistent with having been washed,' and 'the location of the DNA is what tells us when it was put there.' Defense attorney Chad Bowers highlighted, 'My DNA expert found my sperm and his sperm mixed together on the sheets. My DNA expert found an additional person's DNA or sperm on her robe.' The jury returned a verdict of 'guilty to murder in the third degree.'

Lessons

  • Prioritize the preservation of all physical evidence in cold cases, as future technological advancements like DNA profiling can provide breakthroughs decades later.
  • Invest in cold case units and specialized forensic analysis to re-examine unsolved crimes, as persistence can lead to justice even after many years.
  • Understand the complexities of DNA evidence interpretation in legal proceedings, especially when consensual contact is involved, and be prepared to present strong contextual arguments for DNA deposition timing.

Quotes

"

"The word dead just didn't apply. She's she's my sister. There's nothing that could make my sister be dead. I had to go in and see for myself. But my my brother would not allow me to. He put me in a bear hug and he would not let go. He did not want that to be the last memory I had of my sister."

Francesco Keltieri
"

"I'm thinking it's just going to be some minor itty bitty trace. And she says, 'No, we have a lot of it in a lot of locations.'"

Rocco Deo
"

"My own thought is we have a situation in this country from watching CSI and all the crime shows that if your DNA is there, you must be guilty. And I admitted to them that I was having sex with her in her apartment."

Scott Hopkins
"

"There's always this sort of sadness. Even though you you get what you want to some degree, doesn't bring Janet back. She'll always be 23 in 1979. She's still gone."
