Péter Kovács and the Martfű Serial Murders

The first killing and a wrongful conviction

On July 22, 1957, 23-year-old shoe-factory worker Margit Szegedi was killed near Martfű after leaving work. Investigators focused on her colleague János Kirják, who knew her and became an early suspect. Kirják was prosecuted and sentenced to death at first instance. His punishment was later reduced to life imprisonment, but he remained incarcerated for years for a crime he had not committed.

The case is a reminder that a confession or conviction is not necessarily reliable when the surrounding evidence and investigative methods are defective. Later review established that Kirják was not the killer. He was released and rehabilitated after the investigation identified Péter Kovács.

A series emerges

Further women were killed or attacked in the Martfű–Tiszaföldvár area during the following decade. Later archival and legal accounts describe four murders in the established series and two non-fatal attacks. The long gap and the fact that the first murder had already been officially 'solved' helped prevent investigators from initially recognizing a continuing offender.

A decisive break came in 1967 after another woman's body was found near the Körös. Investigators revisited earlier files and began comparing cases that had previously been treated separately. Prosecutors examining the pattern became convinced that a serial offender was active in the region.

The evidence that led to Kovács

The 1967 investigation brought truck driver Péter Kovács into focus. Local archival reporting describes physical evidence connected to his vehicle and the latest crime scene, as well as witness information placing him with the victim shortly before her death. Kovács was taken into custody on August 11, 1967.

He initially denied responsibility and later confessed to multiple crimes. Investigators did not stop with a single admission: the broader inquiry connected the fatal and surviving attacks, and Kovács eventually admitted the earlier offenses that formed the proven series.

Kirják is cleared

Once the evidence against Kovács established that the 1957 murder had been wrongly attributed, Hungary's Supreme Court ordered proceedings that resulted in Kirják's rehabilitation. Legal historical accounts emphasize the role of his original defense lawyer, Ferenc Lánczi, whose work had already prevented the first death sentence from being carried out years earlier.

Kirják's case remains one of the most important aspects of the Martfű record. Crime by Region does not treat his earlier conviction as proof against him: the later proceedings cleared him, and the serial-murder case was prosecuted against Kovács.

Trial, sentence and execution

Kovács was tried for the established sequence of murders and attacks. He was sentenced to death in 1968. The higher court upheld the judgment, and his request for clemency was rejected. Reliable Hungarian sources place his execution on December 1, 1968.

Some later accounts have tried to associate an additional 1955 homicide with Kovács. The theory was discussed by an investigator, but Kovács denied that offense and the available record does not establish it to the same standard as the four murders for which the series is documented. It is therefore excluded from this dossier's victim count.

Timeline

Current status

The case is classified Solved / Adjudicated. Péter Kovács was convicted for the established series and the sentence was executed. János Kirják was exonerated in the case for which he had been wrongly imprisoned. The archive preserves both outcomes because describing the killings without the wrongful conviction would leave out a central part of the investigation's history.
