Key Takeaways
- Danny and Deana Lorenzo, military veterans from Hernando County, were ambushed and killed in April 2018 while meeting a stranger to purchase firearms listed on Armslist.
- The crime scene was described as “bone‑chilling,” with the victims shot execution‑style and their truck riddled with bullet holes indicating a highly trained shooter.
- For eight years the case went cold until investigators noticed a critical error: the suspects placed a personal SIM card into a burner phone, preserving the device’s IMEI number.
- Tracking the IMEI led to Alex Zwiefelhofer, an AWOL soldier from Wisconsin, and subsequently to Craig Lang, who was fighting in Ukraine.
- International cooperation—including FBI agents, Ukrainian courts, and the European Court of Human Rights—enabled Lang’s extradition to the United States in June 2024.
- Both Zwiefelhofer and Lang were convicted of murder and sentenced to life imprisonment; the Lorenzos’ sister, Beverly Dou cet, expressed forgiveness and relief that justice was served.
Background of the Victims
Danny and Deana Lorenzo were a married couple who served in the military before settling in Hernando County, Florida. To supplement their income, they bought and sold items online, frequently using platforms such as Armslist to trade firearms and related gear. Their reputation for finding good deals made them regular participants in online marketplaces, a habit that ultimately placed them in danger when they responded to a seemingly lucrative gun‑sale advertisement.
The Fatal Meeting
In April 2018, the Lorenzos traveled to a shopping center off Corkscrew Road in Estero, believing they were meeting a seller to purchase several firearms. Danny filled out a bill of sale while Deana waited in their truck. Without warning, gunfire erupted, striking both victims in an execution‑style attack. The assailants fled the scene, leaving the couple dead inside the vehicle.
Description of the Crime Scene
The following morning, deputies from the Lee County Sheriff’s Office discovered what they called one of the most gruesome crime scenes they had ever encountered. Sheriff Carmine Marceno described it as “bone‑chilling,” noting the precision of the bullet impacts. Lt. Sarah Rodriguez, the lead detective, recalled the haunting sight of the victims’ bodies and the truck riddled with holes, a testament to the shooter’s skill and cold intent.
Initial Investigation Challenges
Despite the brutality of the crime, the case stalled almost immediately. There were no eyewitnesses, limited forensic evidence, and the perpetrators had taken care to avoid leaving obvious traces. For nearly two years, the investigation remained a “whodunit,” frustrating both law enforcement and the Lorenzos’ family, who clung to hope that the perpetrators would eventually be identified.
The Critical Mistake
The breakthrough came when investigators realized the suspects had made a technical error: they removed the personal SIM card from Danny’s phone and inserted it into a burner phone used to communicate about the Armslist sale. Although they believed the burner phone would conceal their identity, the SIM retained the phone’s International Mobile Equipment Identity (IMEI) number—a unique 15‑digit code tied to the original device. This oversight allowed detectives to trace the device’s activity.
Using IMEI to Track the Suspects
By subpoenaing records associated with the IMEI, the sheriff’s office reconstructed the suspects’ movements from Miami to Estero. This marked the first time the agency employed IMEI‑based tracking in a homicide investigation. The data pointed to Alex Zwiefelhofer, an AWOL soldier from Wisconsin, whose personal phone matched the IMEI recovered from the burner. Zwiefelhofer was already in custody on an unrelated charge, providing investigators with a solid lead.
Identifying the Second Perpetrator
While examining Zwiefelhofer’s background, Detective Rodriguez discovered news articles about him and another former soldier, Craig Lang, who had attempted to travel to South Sudan to join a militant faction. Cross‑checking hotel logs near Miami International Airport revealed Lang’s name on a manifest, linking him to the same network. The realization that both suspects were connected solidified the case: the Lorenzos had been killed to fund the pair’s mercenary ambitions.
International Manhunt for Craig Lang
At the time of the breakthrough, Lang was not in the United States; he was fighting in the war in Ukraine, having become a notable American foreign fighter who had married a Ukrainian woman. Sheriff Marceno contacted FBI Special Agent James Ronciske in Tampa to coordinate Lang’s extradition. The effort was complicated by Ukraine’s ongoing conflict and the need to navigate foreign legal systems, including the Ukrainian courts and the European Court of Human Rights.
Lang’s Return and Trial
In June 2024, after prolonged diplomatic and legal negotiations, Lang was returned to Lee County. Detective Rodriguez described the moment he set foot on U.S. soil as a career highlight. Both Lang and Zwiefelhofer stood trial, were convicted of the Lorenzos’ murders, and received life sentences without the possibility of parole. Sheriff Marceno emphasized the message that the jurisdiction would pursue offenders regardless of where they fled.
Family Reaction and Closure
Beverly Doucet, Danny’s sister, reflected on the eight‑year wait for justice. While she acknowledged the irreversible loss of her brother and sister‑in‑law, she expressed relief that the perpetrators would spend their lives behind bars. Notably, Doucet said she harbors no hatred and has already forgiven the killers, describing the resolution as giving her a sense of newfound family through the community’s support and law‑enforcement dedication.
Legacy of the Case
The Lorenzo case underscores the evolving role of digital forensic tools—such as IMEI tracking—in solving cold cases, especially when suspects make seemingly minor technological missteps. It also highlights the necessity of international cooperation in apprehending fugitives who seek refuge abroad. For the Lee County Sheriff’s Office, the resolution serves as a stark reminder that persistent investigative work, paired with modern technology, can ultimately bring closure to even the most harrowing crimes.
