A Diving Trip That Turned Into a Legal Nightmare
In 2002, Dan Frolec, a 32-year-old from Prague, embarked on a Croatian diving getaway with friends to escape mounting work pressures and a complicated love life. Little did he know that this vacation would spiral into a harrowing ordeal involving a fatal accident, a wrongful murder accusation, and a month-long imprisonment in a foreign country.
The Fateful Dive into Poganica Bay
The group of diving enthusiasts, including experienced diver Tom, close friend Ivo, boat captain Marek, and others, had met at a diving club in the late 1990s. Frolec, who grew up in landlocked Czechoslovakia, had always loved the ocean and seized the opportunity to explore Croatia's waters after the Velvet Revolution opened borders in 1989.
A few days into their trip, the divers discovered a mysterious underwater hole in Poganica Bay, marked by a hand-drawn circle on Marek's map. As evening approached, Michael, one of the divers, excitedly reported that the hole was actually a sea cave. He returned to the boat for more equipment and descended alone, breaking the cardinal rule of always diving with a buddy.
Disappearance and Failed Rescue Attempts
When the other divers emerged from the cave 45 minutes later, Michael was missing. Panic set in as they realized he was alone in the dangerous cave with limited oxygen and inadequate equipment. Frolec and Tom immediately suited up for a rescue mission, with Tom venturing into the cave while Frolec waited outside with a spare air tank.
After what Frolec describes as "the longest 40 minutes of my life," Tom emerged alone, shaking his head to indicate Michael was lost. The group called the Croatian coastguard, who arrived the next morning. Despite Tom's warnings about unsuitable equipment, two coastguard divers attempted a rescue, resulting in one of them also becoming trapped in the cave.
From Witness to Suspect
As the group approached the pier following the failed rescue, police officers were waiting. What Frolec initially assumed was routine investigation quickly turned sinister when he and Ivo were taken to a police station, photographed, fingerprinted, and subjected to a lie-detector test.
"How did Michael die? Did you know that he was stabbed with a knife? Was it your knife?" the officers demanded. Frolec realized with horror that he was being accused of murder, likely because a coastguard diver had also perished in the cave. He failed the polygraph test and was declared a suspect in Michael's murder.
Imprisonment and Media Frenzy
Frolec and Ivo were handcuffed and brought before a judge who ordered them jailed for at least a month while police investigated. They faced the prospect of six months imprisonment without charge and a potential 40-year sentence if convicted.
In jail, Frolec's picture appeared on newspaper front pages alongside accusations of murder. One sensational story even claimed he, Ivo, and Michael were involved in a gay love triangle, leading to harassment from other inmates. His girlfriend Jarka, whom he had recently committed to after ending a five-year relationship, learned of his arrest through a call from the Czech consul.
The Turning Point and Release
After weeks in custody, Frolec's new lawyer made progress. Testimonies from diving buddies and Michael's dive computer data, which showed he had been alive for 30 minutes searching for an exit, disproved the murder theory. The final piece of evidence—red stains on the boat that police claimed were blood—was confirmed through DNA testing to be from mooring ropes.
Michael's stab wounds were determined to be self-inflicted, likely from panic as he scrambled blindly in the silt-filled cave with dwindling oxygen. After nearly a month in jail, Frolec and Ivo were released to a media frenzy at Prague airport.
Life After the Ordeal
The experience profoundly changed Frolec. "It influenced my life in a way that I actually value a lot," he says. "I value my freedom and I take everything with a lot less stress now." He visited Michael's mother with the diving crew to give her a framed photograph of her son taken just hours before the accident.
Frolec and Ivo remain good friends, meeting annually in Prague for Czech beer and conversation. Though they initially discussed Croatia frequently, they've mostly moved on in the more than two decades since. Frolec now lives in Bali with Jarka, now his wife, and their two children. He still dives but avoids cave diving since becoming a father, though he did complete cave-diving training in Florida after the incident to feel more prepared.
The experience served as "confirmation that we belong together" for Frolec and Jarka, whose relationship was tested but strengthened through the crisis. Frolec chronicled his ordeal in a notebook with Cinderella on the cover during his imprisonment, documenting everything from fears about post-9/11 society to moments watching The Simpsons with cellmates.
