The Art of Solving the Unsolvable: How Cold Cases Are Cracked Without DNA
In the murky world of cold cases, some mysteries remain unsolved for decades. Others, surprisingly, find closure through grit, strategy, and unexpected breaks. While DNA has transformed criminal investigations, it’s not always available. When it isn’t, success hinges on something far more timeless—human intuition and relentless dedication.
Let’s explore three remarkable cases where justice prevailed without the power of DNA.
Rebekah Gould’s Case: A Facebook Group Helped Crack It
Back in September 2004, 22-year-old Rebekah Gould disappeared while visiting her small hometown of Melbourne, Arkansas. A few days later, authorities discovered her body dumped near a rural highway. Despite efforts by law enforcement, the investigation stalled for years.
However, nearly two decades later, true crime author George Jared and criminal investigator Jen Bucholtz reignited interest in the case. They launched a Facebook group called “Unsolved Murder of Rebekah Gould”—a platform that soon attracted amateur sleuths and curious minds alike.
As discussions unfolded, one member stood out: William Miller, the cousin of Rebekah’s then-boyfriend. His strange behavior raised red flags. Eventually, a tipster contacted the group and claimed Miller had been in town during the murder weekend. Investigators confirmed this lead and set a trap.
Detective Mike McNeil worked tirelessly behind the scenes. Ten months later, he arrested Miller. He eventually confessed to the murder, admitting he bludgeoned Rebekah with a piano leg and dumped her body. By 2022, the court sentenced him to 40 years. Ironically, what law enforcement couldn’t accomplish in 18 years, a Facebook community achieved in less than one.
Jasmine Porter’s Story: A Whisper from the Past Uncovered the Truth
Jasmine “Jazzy” Porter suffered a tragic fate in 1996 when someone raped and strangled her in her Bronx apartment. Her five-year-old son was the only witness. Despite their efforts, police couldn’t link anyone to the crime, and the case went cold.
Fast forward to 2021—Detective Robert Klein received a chilling tip from a jailhouse informant. They had overheard a cryptic conversation that referenced Porter’s unsolved murder. This clue prompted Klein to dive back into the decades-old files.
While combing through evidence, he noticed something everyone else had overlooked: Jasmine’s fingernail clippings. Improved forensic technology offered an opportunity. Although not DNA-free, this form of forensic testing fell outside conventional DNA-matching practices.
The results pointed to Gregory Fleetwood, a man with no direct connection to Porter. His arrest in 2022 reignited hope. According to Klein, Porter’s family had never stopped grieving. “For them,” he said, “this case was never cold.” Fleetwood now awaits trial, finally offering Jasmine’s loved ones a glimpse of justice.
Gretchen Harrington’s Cold Case: A Startling Confession Ends Silence
Eight-year-old Gretchen Harrington vanished in 1975 while walking to Bible camp in Marple Township, Pennsylvania. A search led to the discovery of her beaten body in a wooded area. Investigators worked tirelessly but failed to identify a suspect.
Nearly 48 years later, in 2023, a woman stepped forward with a disturbing childhood memory. She recalled an attempted abduction by David Zandstra, the very pastor who was supposed to watch over Gretchen. Police approached Zandstra to collect DNA, yet instead of resisting, he confessed outright.
That moment, captured on tape, broke decades of silence. Zandstra detailed how he abducted, assaulted, and murdered Gretchen. Despite the weight of his confession, the court ruled it inadmissible during his 2025 trial. His defense argued coercion, and the jury acquitted him.
Although he walked free, investigators began comparing his DNA to other unsolved cases in regions where he had once lived. Law enforcement remains committed to uncovering the full extent of his crimes.
Why Are Cold Cases So Difficult to Solve?
Cold cases challenge even the most seasoned detectives. Unlike fresh investigations, these cases offer little in the way of active leads. Over time, witnesses die, move away, or forget crucial details. Moreover, evidence can degrade, become misplaced, or simply disappear due to poor storage practices.
Most police departments also face staff shortages and limited budgets. Cold cases often take a backseat to active investigations. This lack of resources stretches timelines and exhausts investigators.
Even when evidence survives, connecting dots from decades ago demands not just hard work—but creativity. Investigators must think like the suspect, question assumptions, and dig where no one else has.
Why Old-School Detective Work Still Wins
Despite modern forensic tools, traditional methods still drive breakthroughs. Door-to-door interviews, witness re-contact, timeline reconstruction, and even media exposure often reignite stalled cases. In Rebekah Gould’s case, a simple Facebook group proved more effective than any DNA test.
Social media now plays a unique role in cold case investigations. It helps spread awareness, reach long-lost witnesses, and encourage anonymous tips. These platforms empower communities to participate in solving crimes once considered unsolvable.
Above all, it’s the investigators’ determination—refusing to give up—that makes the biggest difference.
Patience, Legwork and a Bit of Luck
In the absence of DNA, investigators must rely on grit, intuition, and the willingness to dig through years of forgotten details. As these three powerful stories show, justice can still prevail—even after decades of silence.
Every re-opened file carries the hope of closure. Each name remembered, each memory unearthed, might hold the key to justice.
Frequently Asked Questions
Can a cold case be solved without DNA?
Yes, many cold cases have been solved through witness statements, confessions, forensic testing other than DNA, and even social media.
How long can a murder case stay unsolved?
There’s no time limit. Some cases remain open for decades, waiting for the right clue, tip, or confession.
Why don’t police solve more cold cases?
Limited resources, faded memories, and lost evidence make cold cases extremely difficult to investigate compared to fresh ones.
Is social media useful in cold case investigations?
Absolutely. Platforms like Facebook and Reddit often generate leads, connect people, and help keep public interest alive.
What’s the oldest cold case ever solved?
One of the oldest is the 1957 murder of Maria Ridulph, solved in 2011—over 50 years later—without DNA.
Do cold case investigators work full-time?
In most departments, no. Detectives often juggle cold cases alongside active investigations due to limited staffing.
