Marian Peci: 49 prior convictions before the sexual assault of a teenage girl
An intoxicated teenage girl said no and struggled to get away after Marian Peci led her from her friends. A jury convicted the Slovakian national of sexual assault and false imprisonment. At sentencing, the court heard that he already had 49 convictions. The probation material recorded no remorse, deflection and minimisation.
Marian Peci and another adult man came across three teenage girls drinking beside a disused railway line in County Mayo. They offered the girls more alcohol and joined their group. Peci then took one of the girls away, sexually assaulted her and prevented her from freely leaving until her friends reached her.
This is not an allegation awaiting trial. Peci denied sexual assault and false imprisonment, but a Central Criminal Court jury convicted him of both offences. On 16 January 2026, Mr Justice Paul McDermott sentenced him to three years in prison and ordered two years of supervision after release.
The sexual convictions were not Peci's first encounter with the criminal courts. The sentencing report records 49 previous convictions for public-order, theft and road-traffic offences. The case therefore raises an unavoidable public-protection question: what happens when a decade of repeated offending culminates in sexual violence against a vulnerable teenager?
Teenagers approached beside a railway line
On 28 March 2023, three teenage girls had gone to a disused railway line in County Mayo to drink alcohol. There they encountered Peci and Rudolf Makula, who offered the girls more alcohol and entered their company.
Mr Justice McDermott later stressed the imbalance. The two men were substantially older and more experienced than the girls. The judge found that they saw an opportunity to insinuate themselves into the group and exploit the teenagers for their own sexual satisfaction.
The supply of further alcohol was an aggravating feature, not a side detail. It made already-young victims more vulnerable. The judge said young women socialising at night should not have to face older men preying on them.
She said no and struggled to get away
The girl whom Peci targeted was described in court as extremely intoxicated and unable to remember every part of what happened. She later told gardaí that Peci grabbed her and led her away from the group.
He kissed her and touched her breasts and bottom. He asked her for sex. She said no. When she tried to get away, she struggled until friends found her and led her to safety.
A third girl had contacted two young male friends, who arrived and helped the teenagers. The judge commended those young men and said the girls were fortunate their friend had called them.
The published record protects the girls' identities. This report does the same. It does not name them, reproduce identifying details or speculate about their lives.
A jury rejected Peci's denial
Unlike Makula, who pleaded guilty in relation to the other girl, Peci denied the charges against him. His case was tested at trial. A jury found him guilty of both sexual assault and false imprisonment.
That legal distinction matters. Peci was not convicted merely because he was present with Makula or because the two men were tried in connected proceedings. His own convictions concern his own conduct toward the second girl.
Footage from the local area was analysed after the incident and the two men were identified as suspects. The public sentencing reports do not provide the trial date or a complete transcript of the evidence. This case file therefore does not invent a fuller evidential narrative than the court reporting supports.
No remorse, deflection and minimisation in the probation material
At sentencing, Mr Justice McDermott described the probation reports relating to the two offenders as disappointing. The reports included no remorse, as well as deflection and minimisation of the offending.
That finding should be stated with precision. The published report discusses the probation material for both men together; it does not reproduce a separate assessment paragraph for each defendant. It nevertheless formed part of the sentencing record in Peci's case.
The judge said the men had treated the girls in a demeaning and humiliating manner and behaved as if entitled to do what they wanted. The victims, not the offenders, were left carrying the consequences.
What the victim said the assault took from her
The two girls supplied victim-impact evidence describing fear, shame, damaged trust and disruption to education and everyday life. One said her life had stopped for almost two years and that the assault had taken years from her rather than hurting her only once.
Because the published sentencing report presents both statements in the connected case, this report does not assign every quoted impact to Peci's victim unless the source clearly does so. The central point remains uncontested: the court received stark evidence of lasting damage to both teenagers.
Mr Justice McDermott told the girls that what happened was not their fault. He praised the courage required to carry the case through the criminal process.
Forty-nine convictions before this sentence
The court was told that Peci had 49 previous convictions encompassing public-order, theft and road-traffic offending. The report does not list all 49 dates, charges or outcomes, and this case file does not pretend that it does.
Separate local court reports show why name-based criminal histories require care. A July 2025 Longford report described a Slovakian man named Marian Peci, with a Roscommon address, who pleaded guilty to being drunk in charge of a vehicle and failing to provide a specimen. That report recorded 37 previous convictions at that point.
A January 2026 Ballina report concerned a 30-year-old Marian Peci from Roscommon who was found intoxicated in a betting shop. The court was told of ten years of offending, and a fine was imposed. A February 2026 Roscommon report identified “Marian Peci Jnr” and imposed a concurrent three-month term for criminal damage committed in August 2025.
The names, ages, nationality and Roscommon connections overlap strongly. However, the ancillary reports do not publish a unique court identifier and contain differing family details. They are therefore linked here as potentially related public records, not silently merged into the Central Criminal Court defendant's proven history. The firm figure for this case file is the one reported at his sexual-offence sentencing: 49 priors.
Three years in prison and two years under supervision
On 16 January 2026, Mr Justice McDermott imposed a three-year prison sentence on Peci. Both Peci and Makula had been in custody since August 2025. The judge also ordered two years of post-release supervision for each man.
The supervision order extends the public-protection response beyond the prison gate. It does not add two years to the custodial term. The Sex Offenders Act provides the statutory framework for supervision of convicted sex offenders after release, with conditions directed toward preventing further offending and supporting rehabilitation.
No published appeal by Peci was located in exact-name searches through 28 July 2026. That is not proof that no notice, application or unreported proceeding exists. It means the public record reviewed for this report leaves the jury verdicts, three-year term and supervision order standing as the known outcome.
Case chronology
- 28 March 2023: Peci and Makula meet three teenage girls drinking beside a disused railway line in County Mayo and offer them more alcohol.
- During the encounter: Peci leads one extremely intoxicated girl away, sexually touches her and asks for sex. She says no and struggles to get away.
- Rescue: Two friends summoned by the third girl arrive and help the teenagers leave.
- Trial: Peci denies sexual assault and false imprisonment; a Central Criminal Court jury convicts him of both charges.
- August 2025: The reported period of custody begins.
- 16 January 2026: Mr Justice Paul McDermott imposes three years' imprisonment and two years of post-release supervision.
A caveated custody-cost benchmark
The Irish Prison Service reported an average annual cost of €99,072 for an available, staffed prison space in 2024, excluding capital expenditure. Applying that system-wide average to the nominal three-year sentence produces a gross illustration of €297,216.
This is not Peci's personal invoice, a claim about marginal expenditure or a prediction of the exact time he will spend in custody. His reported custody began before sentence, and remission, release decisions and historic annual costs affect any real total. The calculation simply shows the scale of a full three-year prison-space commitment at the latest cited average.
The illustration excludes Garda investigation, prosecution, court administration, criminal legal aid, probation work, two years of post-release supervision and victim services. No reliable case-specific figures for those services were located, so none are invented here.
Nationality is established; immigration history is not
Defence counsel described Peci at sentencing as a Slovakian national. Slovakia is an EU member state. Those are the limits of the established origin and status facts in the sources reviewed.
The public reports do not establish when Peci entered Ireland, the legal basis of his residence, whether any EU free-movement restriction was ever considered or whether a removal decision exists. Nationality does not prove unlawful residence, asylum history or a deportation outcome.
The accountability question can be asked without manufacturing an immigration file: after 49 prior convictions and two new sexual-offence verdicts, what public-protection assessment will occur before the custodial and supervision periods end?
The warning in this record
The record is not simply a count of offences. A teenage girl said no. She tried to leave. An older man who had joined her group through an offer of alcohol sexually assaulted and confined her. His denial was tested, and a jury convicted him.
By sentencing, Peci had accumulated 49 previous convictions across three broad categories. The probation material then disclosed no remorse, deflection and minimisation. A three-year sentence and two years of supervision followed.
That sequence is the warning: repeated lower-level and acquisitive offending can coexist with escalating public-protection risk. A serious system should preserve the complete criminal record, enforce supervision and make lawful status decisions on verified facts before another victim is asked to bear the cost of institutional drift.
