THE BRIEF: The Disappearance of Lars Mittank
SECTION 1 — VERDICT
Lars Mittank, a 28‑year‑old German power‑plant worker, vanished from Varna Airport on 8 July 2014 after sprinting out of the terminal, scaling a perimeter fence, and running into the surrounding fields. His passport, wallet, phone, and luggage were left behind; no confirmed sighting, financial transaction, or phone activity has been linked to him since that morning. Extensive ground searches using drones, cadaver dogs, and mantrailing dogs found no human remains, clothing, or other physical trace. The German Bundeskriminalamt (BKA) has issued an international missing‑person alert, and Interpol is involved, but the investigation remains open and unsolved.
A set of serious, medically and procedurally grounded questions has never been resolved by the official inquiry. Two medical specialists who contacted police after a 2015 television appeal suggested that the antibiotic cefprozil — prescribed to Mittank for a perforated eardrum — could have triggered an acute psychosis, a possibility consistent with the drug’s rare central‑nervous‑system side‑effects. That hypothesis sits alongside Mittank’s own reported statements — relayed by his mother, Sandra Mittank, during the continuous phone calls documented by the BKA — that “people are trying to kill me,” “they won’t let me fly,” and “I don’t want to die.” The convergence of a construction‑worker’s intrusion into his medical examination, immediately before his flight, and the conflicting medical advice he received — one doctor warned against flying, the airport doctor cleared him as fit — add to the uncertainty. Yet no independent medical record, no identification of the four men who fought him two days earlier, and no forensic trace have emerged to differentiate a psychotic crisis from a flight from a genuine, un‑identified threat. These questions are real and unresolved. Their existence establishes that the official account is incomplete. It does not establish any alternative account of what occurred, or who, if anyone, is responsible.
What the available evidence cannot establish is whether Lars Mittank is alive or dead, whether the fear he reportedly expressed was the product of a psychiatric event or a rational response to an external danger, and what agent — human or medical — caused his disappearance.
SECTION 2 — CASE SUMMARY
Lars Joachim Mittank, born on 9 February 1986 in Berlin and raised in Itzehoe, northern Germany, was 28 years old in the summer of 2014. He worked for GDF Suez at a power plant in Wilhelmshaven and commuted nearly every weekend to help care for his father, who had suffered a stroke a couple of years earlier. In early July 2014 he travelled to Varna, Bulgaria, for a holiday with friends.
On the evening of 6 July, Mittank was involved in a fight outside a bar with four other German men, reportedly over a football rivalry. He suffered a perforated eardrum and was treated at a Varna hospital. A doctor there advised him not to fly; the antibiotic cefprozil (Cefzil 500) was prescribed. The following day he moved to the Hotel Color near the airport, and during the night of 7–8 July he made a series of increasingly frightened phone calls to his mother in Germany, telling her he did not feel safe and that people were trying to kill him.
On the morning of 8 July he took a taxi to Varna Airport. According to his mother, he texted her, “I made it to the airport.” At the airport medical office he saw Dr. Kostov, who reportedly cleared him as fit to fly. During that consultation a construction worker entered the room; Mittank immediately panicked, sprinted through the terminal, abandoned his belongings, reached the car park, scaled the perimeter fence, and disappeared into the surrounding fields — an event captured on security cameras at 10:11 a.m. Bulgarian authorities searched the area with drones, cadaver dogs, and mantrailing dogs but found nothing.
The BKA opened a missing‑person investigation and issued an international alert through Interpol. In 2015 the case was featured on the ZDF crime‑appeal programme “Aktenzeichen XY … Ungelöst.” Several unconfirmed sightings and a mistaken identification in 2016 have followed, but no substantive lead has closed the case.
SECTION 3 — FULL RECORD
Evidentiary Posture
The record consists primarily of the BKA’s official missing‑person alert, the widely‑circulated airport CCTV footage, contemporaneous press reporting, statements made by Sandra Mittank to journalists and television investigators, and a 2015 ZDF documentary appeal that solicited tips. There are no adversarial court proceedings, coroner’s inquest, or published forensic-medical findings. The Bulgarian police have not disclosed any formal conclusion, and the investigation remains administratively a missing‑person case. The core evidential constraints are the absence of Mittank’s own body or physical trace, the lack of any independent record of the conversations he had with his mother during the final hours, and the fact that the persons most directly involved — the four fighters, the construction worker, the airport doctor — have never been publicly identified or questioned in a way that produced an official finding.
Observed Facts vs. Inferred Claims
Observed facts: Mittank is last seen on CCTV at Varna Airport at 10:11 a.m. on 8 July 2014, sprinting out of the terminal, crossing the car park, climbing a fence, and vanishing into vegetation. He left behind his passport, wallet, mobile phone, and luggage. No confirmed sighting, financial activity, or digital trace has been linked to him after that date. The BKA missing‑person alert records that he was in continuous phone contact with his mother in the hours beforehand. Extensive ground searches produced no human remains or clothing.
Inferred claims: The content of Mittank’s last telephone calls is known only from Sandra Mittank’s recollections — statements such as “I don’t feel safe,” “people are trying to kill me,” “they won’t let me fly and they won’t let me drive either,” and “I don’t want to die.” The suggestion that the antibiotic cefprozil could have induced a psychotic episode was raised by two unnamed medical specialists after the 2015 television broadcast. The construction‑worker’s entry into the examination room and the contradiction between medical advice not to fly and the airport doctor’s clearance are reported by news outlets but not sourced to an official police report. All of these are credible inferences but lack independent corroboration.

Source Weighting
The BKA’s official missing‑person alert, issued through Interpol and anchored in the German criminal police authority, is the most reliable institutional record. The ZDF broadcast was produced by a public broadcaster with access to case investigators and solicited vetted tips; it carries substantial editorial weight. Press reports sourced from interviews with Sandra Mittank, the family’s private investigator, or official spokespersons provide the bulk of the narrative detail; they are broadly consistent but rely on single‑source accounts. The statements attributed to Mittank by his mother are hearsay and cannot be independently verified, though the BKA’s confirmation of continuous phone contact gives them a foundation. Unconfirmed sightings and online speculation carry no independent evidentiary weight.
Anomalies
- Construction‑worker intrusion (HIGH): During the airport medical examination, a construction worker entered the room, and Mittank immediately fled. The timing is uncanny and the worker’s identity and purpose have never been disclosed; no official witness statement is public.
- Antibiotic‑induced psychosis tip (HIGH): Two medical specialists suggested that cefprozil could have triggered an acute psychotic reaction, a hypothesis now partially supported by the drug’s later‑revised side‑effect label. This remains a credible, un‑dismissed medical concern that the authorities have not, so far as the record shows, formally ruled out.
- Total absence of physical trace (HIGH): Despite drones, cadaver dogs, and mantrailing dogs, no body, clothing, or forensic trace has been found in the open terrain around the airport. While wildlife or inaccessible land could explain the absence, the complete disappearance of a 28‑year‑old man without supplies or local connections is unusual.
- Conflicting medical advice (MODERATE): A hospital doctor initially advised Mittank not to fly; the airport doctor later cleared him as fit. Without the medical records, it is impossible to know whether the change reflected a real improvement or a misjudgment.
- Unidentified fighters (MODERATE): The four German men involved in the fistfight on 6 July were never identified or questioned, leaving open the possibility that the altercation was more than a random football argument.
Motive and Mechanism
No motive for a deliberate harm has been identified; the record contains no evidence of a financial, personal, or institutional interest in Mittank’s disappearance. The two principal hypotheses — a medical crisis (antibiotic‑triggered psychosis) and a flight from a genuine, still‑unknown threat — each propose a different mechanism but neither has been confirmed. The absence of a body equally accommodates a fatality that eluded searchers or a successful evasion.
Competing Theories
| Theory | Key elements | Confidence |
|---|---|---|
| Psychiatric crisis induced by cefprozil | The antibiotic carries a rare CNS side‑effect; Mittank had no known prior psychiatric history; his reported statements and panic are consistent with a psychotic break. Two specialists raised the possibility. | UNPROVEN but medically credible |
| Flight from a real, un‑identified threat | Mittank’s reported fears, the pre‑trip caution (leaving his new smartphone at home), the intrusion of the construction worker, and the absence of a body are taken as signs that he fled danger. | UNPROVEN; no threat source has been found |
| Hitch‑hiking sighting near Varna (∼2015) | A truck driver claimed to have seen Mittank; the description included tired eyes and prominent cheekbones. | UNCONFIRMED; no corroboration |
| Sighting in Schildow (2019) | Anonymous report of a man resembling Mittank taken by a trucker to Schildow, north of Berlin. | UNCONFIRMED; not verified by police |
| Misidentification as Anton Pilipa (2016) | A Canadian man found in Brazil was briefly thought to be Mittank; DNA and fingerprints excluded the match. | DISPROVED |
| Amnesia hypothesis (family belief) | Sandra Mittank hopes her son is alive and suffering from amnesia; this is a hope, not an evidence‑based finding. | FAMILY BELIEF; no supporting evidence |
THE OPEN QUESTIONS: UNRESOLVED MEDICAL, PROCEDURAL, AND EVIDENTIARY ISSUES
The investigation into Lars Mittank’s disappearance has not answered several questions that bear directly on whether his final actions arose from a medical emergency or from a danger the inquiry failed to detect.
Could the prescribed antibiotic have precipitated a psychotic episode? After the 2015 “Aktenzeichen XY” broadcast, two medical professionals contacted police to warn that cefprozil can, in rare cases, cause serious psychiatric side‑effects. The drug’s modern safety label now includes such warnings. The timing fits: Mittank began taking the medication after a hospital visit on 6 July, and his behaviour escalated dramatically over the next 48 hours. Yet no blood‑test or medical‑examination result from the relevant period has been made public, and the authorities have not indicated whether they pursued this lead.
Why did the medical advice about flying reverse? A Varna hospital doctor reportedly told Mittank not to fly because of his perforated eardrum. Two days later, the airport doctor cleared him. Without access to the clinical notes, it is impossible to judge whether the eardrum had healed sufficiently, whether the antibiotic was affecting his cognition, or whether the clearance was erroneous.
Who was the construction worker who entered the examination room, and what effect did his appearance have? The intrusion occurred seconds before Mittank ran. The worker has never been named or questioned on the public record, leaving a gap in the timeline that could be coincidence or a trigger for an already‑frightened man.
How can a man leave no forensic trace in the immediate surroundings of a busy airport? A field of sunflowers and scrub was searched with drones, cadaver dogs, and mantrailing dogs. The absence of remains, clothing, or any scent trail beyond the airport fence is itself a defining feature of the case, consistent both with a body that has not yet been found and with a person who was picked up and removed from the area. No independent search‑protocol review is available.
Were the four German men from the fistfight ever investigated? The fight on 6 July, reportedly over football allegiances, is the only known incident of interpersonal violence during Mittank’s trip. No source indicates that the four men were identified or interviewed. If the confrontation was not as trivial as it was first assumed, it may hold a trace of the threat Mittank later described.
These questions are real and unresolved. Their existence establishes that the official account is incomplete. It does not establish any alternative account of what occurred, or who, if anyone, is responsible.
What the Evidence Best Supports
The evidence best supports that Lars Mittank was in a state of intense alarm — captured on camera and reflected in the reported phone calls — when he left Varna Airport and disappeared into the surrounding countryside. Both a medical crisis and a flight from a real danger are compatible with the known facts, but neither has been substantiated. The case remains a missing‑person investigation without a conclusion.
SECTION 4 — WHAT REMAINS UNKNOWN
It is not known whether Lars Mittank is alive or dead. The cause of the fear he displayed — whether a drug‑induced psychotic break, a rational response to an external threat, or something else — cannot be determined from the public evidence. The fate of his body, if he died, and the mechanism of that death are unknown. The identity of any person or group that might have threatened him, if such a threat existed, has never been established. Finally, whether the investigation has exhausted all avenues or whether important leads were overlooked is, in the absence of a formal finding, impossible to assess.
SECTION 5 — METHODOLOGICAL NOTE
This case rests on an unrecorded private state: the authenticity of a missing person’s reported fear. The behaviour is seen, the words are heard second‑hand, but whether those words correspond to a medical emergency or to a danger that remains hidden is not something the available evidence can answer. Without access to Mittank’s medical records, the full content of his telephone calls, or the testimony of the few people who interacted with him in his final measured hours, the record stops at the fence line.
