Cage fighter seeks to have murder conviction declared a miscarriage of justice

A Polish cage fighter serving a life sentence for the 2014 murder of a young man in County Roscommon has initiated fresh legal proceedings at the Court of Appeal to challenge his conviction on grounds of miscarriage of justice. Leszek Sychulec, now in his 40s and formerly resident in Ballymahon, County Longford, was convicted in 2016 alongside co-accused Andrzej Gruchacz for the killing of Patryk Krupa near Athlone. The victim sustained a severe head injury during a violent assault and subsequently drowned in the River Shannon while incapacitated. A jury returned unanimous guilty verdicts after five hours of deliberation, leading to mandatory life sentences for both men. An appeal heard in 2018 upheld the convictions in their entirety. However, at a case management hearing conducted before Ms Justice Isobel Kennedy on 15 May 2026, Sychulec's legal team contended that material evidence relevant to prosecution witnesses had been withheld, thereby constituting grounds for declaring the conviction unsafe. The prosecution and defence were directed to collaborate on resolving disclosure matters, with the court adjourning proceedings to 3 July to permit further evidence to be properly examined. Sychulec's legal representatives were ordered to file an affidavit containing new evidence by 15 June. The original 2016 trial heard evidence including DNA recovered from Sychulec's belongings, witness testimony, photographic documentation of drag marks leading to the water, and CCTV footage from Collins Service Station establishing both men's presence at the scene. The trial judge described the offence as shocking and violent. Earlier grounds of appeal had challenged the identification procedures employed by gardaí, arguing that witnesses were shown a single photograph rather than a range of images, and raised concerns regarding the admissibility of identification evidence. The current application represents a further attempt to overturn a conviction that has remained firm through previous appellate scrutiny.
