Lukasz Stachura, 41, told friends that he had killed Kamil Leszczynski when they questioned why they hadn’t heard from the 33-year-old.
Stachura had already killed Mr Leszczynski on 27 June 2021 and dumped his body close to a farm track in fields off Turvey Road, between the villages of Carlton and Turvey.
Luton Crown Court heard that Mr Leszczynski had endured “severe physical suffering” at the hands of Stachura, who bound his victim’s hands with phone cables and gagged his mouth with a makeshift gig.
