Sentenced to Life for Murdering “Sadza”, Jacek Wach Faces Decades of Legal Chaos Over Wrong Body Identification

Convicted of murder in 2003 based on a corpse later found to belong to someone else, Polish criminal Jacek Wach endures a two-decade legal battle marked by false confessions, bungled investigations, and shifting court verdicts.

The 1997 Car Bombing and the Underground Investigation

In December 1997, a car bomb exploded beneath the vehicle of Krzysztof A., known as “Siwy,” a Suwałki businessman with ties to the criminal underworld, leaving him severely injured and missing a leg. Police failed to find the perpetrator, prompting “Siwy” and newly released criminal Jacek Wach to form a self-appointed investigative team alongside local mafia members to hunt down those responsible.

The vigilante group resorted to brutal interrogations, abductions, and extortion targeting anyone suspected of involvement in the bombing. On April 16, 1999, 28-year-old Tomasz S., known as “Sadza,” went missing after work, drawing the attention of prosecutors who briefly detained several individuals before closing the inactive investigation.

The Discovery of Remains and the 2003 Life Sentence

In August 1999, a tourist discovered a decomposing human head and body parts in Lake Pluszne, which DNA testing and superprojection identified as the missing Tomasz S. Police subsequently arrested Krzysztof A., Marek J., Adam S., and Jacek Wach, relying partly on testimony from criminal Tadeusz F., who claimed to have witnessed Wach shooting the victim.

Despite defense questions regarding discrepancies in dental records and scars, the court sentenced Jacek Wach to life imprisonment on June 13, 2003, for torturing and killing Tomasz S., while co-conspirators received prison terms ranging from five to 12 years. The Supreme Court later upheld the life sentence despite appeals concerning the key witness’s mental health.

A Confession and the Unraveling of the Case

In 2013, imprisoned criminal Wiesław S. confessed to a prosecutor that he, not Wach, had actually murdered Tomasz S., stating he strangled the victim with a cord and buried him in a forest rather than dismembering and dumping him in a lake. Wiesław S. detailed how they had held “Sadza” in a custom-built cage and tortured him with a power drill to force a false confession regarding the car bombing.

Following this confession and a Supreme Court decision, Wach’s life sentence was overturned in March 2015 for a retrial. Meanwhile, key witness Tadeusz F. admitted to fabricating his original testimony after being coached and promised lenient treatment by police officers, triggering a domino effect of witnesses retracting their prior statements.

Decades of Legal Battles and Retried Sentences

The Olsztyn Regional Court sentenced Wach to a cumulative 15 years in prison in late 2015 for other criminal acts, but prosecutors successfully appealed the ruling. Subsequent proceedings stalled due to defense motions highlighting the legal impossibility of Wach being guilty of murdering a victim whose actual killer had already confessed, creating a complex double-jeopardy dilemma.

In May 2020, the Olsztyn court acquitted Wach of the murder charge while convicting him of kidnapping and torture, sentencing him to 10 years in prison. However, on December 2, 2022—exactly 25 years after the initial car bombing—an appeals court reinstated a life sentence before the Białystok Court of Appeal reduced the penalty back to 10 years of isolation in April 2024.
