An evening run that became a homicide investigation
On September 25, 2013, Kardosné Gyurik Krisztina left home for her usual evening run in Soroksár, Budapest's XXIII district. When she did not return, her family began searching. Her body was later located close to her normal running route.
The killing generated intense public attention and an extensive police inquiry. Early reporting reflected uncertainty about whether more than one attacker might have been involved. That uncertainty should not be confused with the later evidentiary record: the final prosecution and judgment identified R. Szilveszter as the perpetrator.
Five years without an identified killer
For roughly five years the case remained unsolved. Investigators pursued numerous leads, collected large amounts of genetic material and re-examined evidence as forensic work continued. The length of the investigation became part of the case's public significance because the attacker remained unidentified despite the scale of the inquiry.
In 2018, investigators identified R. Szilveszter, who was already in prison in an unrelated matter. Reporting on the breakthrough emphasized two important evidentiary links: genetic traces connected him to the crime scene and the victim's mobile phone had come into his possession.
The defendant's account
R. Szilveszter denied killing Krisztina. His defense eventually argued that he had encountered her after the attack, handled the body and taken valuables, but had not committed the homicide or sexual assault. The courts did not accept that explanation.
Expert evidence became central at trial. Telex reported that multiple biological traces carried the defendant's genetic profile, while a second male DNA profile that had complicated the investigation was ultimately explained as contamination unrelated to a second attacker.
The 2021 first-instance conviction
On October 15, 2021, the Metropolitan Court found R. Szilveszter guilty of homicide committed for a base purpose, sexual violence and robbery-related conduct. It imposed life imprisonment and set the earliest possible conditional release after thirty-five years.
That judgment was not final. Both prosecution and defense appealed: prosecutors sought a harsher parole minimum, while the defense continued to seek acquittal on the homicide and sexual-violence counts.
The final appellate judgment
On June 22, 2022, the Metropolitan Court of Appeal issued the final judgment. It maintained life imprisonment and increased the earliest possible conditional-release point from thirty-five to forty years. The appellate court also addressed the legal relationship between the sexual violence and the homicide, treating the sexual offense as absorbed into the aggravated homicide classification for sentencing purposes.
The court rejected the defendant's account that he had merely found the victim and taken property. Its reasoning relied on the combined forensic and circumstantial record rather than on any single public allegation made during the earlier unresolved years.
Why the cold-case history matters
The Soroksár case illustrates how an investigation can remain open for years despite substantial evidence collection, then change when forensic results are matched to a person already known to authorities. It also shows why early theories about multiple offenders should not be carried forward after later evidence contradicts them.
Crime by Region therefore separates the uncertainty of 2013–2018 from the final adjudication reached in 2022. The five-year period without an identified perpetrator is part of the investigation history, but the case's present legal status is resolved.
Timeline
September 25, 2013: Kardosné Gyurik Krisztina is attacked while jogging in Soroksár and is found dead near her regular route.
2013–2018: police pursue a large-scale investigation without identifying a prosecutable suspect.
September 2018: R. Szilveszter, already imprisoned in another matter, is publicly identified as the new suspect after evidentiary links emerge.
October 15, 2021: the Metropolitan Court convicts him at first instance and imposes life imprisonment with possible parole after thirty-five years.
June 22, 2022: the Metropolitan Court of Appeal issues a final judgment, maintaining life imprisonment and extending the parole minimum to forty years.
Current status
The case is classified Solved / Adjudicated. R. Szilveszter's conviction became final in June 2022. His denial of the homicide is part of the procedural record, but the final court judgment rejected that defense after reviewing the forensic and circumstantial evidence.
