Wacław Kiełtyka

In September 2019, Kiełtyka was named as the new Machine Head lead guitarist in a post on the band's Facebook page by founding member Robb Flynn.

Charges were dropped by prosecutors in January 2018, citing the "well-being of the victim" and "in the interest of justice", and the scheduled trial later that month was cancelled. The charges were dropped without prejudice, leaving the possibility of future charges open. According to Piotrowski's attorney Jeffry Finer, the accuser was heavily involved in the decision to drop charges. The defence attorneys also highlighted testimonies from numerous concert attendees and musicians from other bands in support of the band's version of events.

In March 2018, Kiełtyka wrote a lengthy statement on behalf of the band where he announced the band's return and addressed the band's hiatus from music resulting from the criminal charges. Decrying the accusations made against the band as false, he wrote, "Does sexual harassment happen and do crimes against women exist? Yes, and it is horrible. Do false accusations happen? Yes, this really happens. And it is also horrible. (...) We cannot and we will never accept someone else's narration about who we are. That is why we have chosen to return with the band. We know who we are and we can hold our heads and our music high with that knowledge."

On 9 September 2017, all four members of Decapitated (Michal Łysejko, Kiełtyka, Rafał Piotrowski and Hubert Więcek) were arrested in Santa Ana, California after a show, and were charged with first-degree kidnapping in relation to an incident alleged to have happened after the band's show at Spokane, Washington's The Pin on 31 August 2017. Prior to the arrest, the band members had offered to surrender to the police as soon as they had learned of an investigation, but never heard anything back.

After being extracted to Spokane, each band member was formally charged with rape in October 2017. Piotrowski and Kiełtyka were both charged with second degree rape, while Łysejko and Więcek's charges were for third degree rape. This was in contrast to earlier reports, which had depicted Piotrowski and Więcek as the primary aggressors. Kiełtyka was represented by defense attorney Steve Graham. All members of the band plead not guilty to their respective criminal charges.

Kiełtyka auditioned for second guitarist of Morbid Angel after the departure of Erik Rutan in 2006. Before joining Vader in 2009, Kiełtyka was a music store salesman. He also worked as a guitar technician for the band Hypocrisy.
