Overview

• Christophe Borgye, 35, was killed in May 2009 by three housemates in Ellesmere Port, with a hammer causing fatal injuries after an initial knife attack, before his body was entombed in concrete in the garden outbuilding.
• Former inspector Anton Sullivan, a French speaker, recalls Sebastian Bendou’s phone-box confession in April 2013, which identified Borgye and led police to the remains and subsequent arrests.
• Receipts and financial records documented planning and the aftermath, including purchases of cement and knives, use of Borgye’s bank card, and a lunch at Chiquito’s at Cheshire Oaks hours after the killing.
• Investigators concluded Dominik Kocher orchestrated the scheme and controlled household finances, selling Borgye’s belongings and directing the cover-up.
• Courts handed life sentences: Kocher received a 23-year minimum term, Bendou a 14-year minimum after a separate trial, and Manuel Wagner a 16-year minimum following a 2017 murder conviction.
