Police are investigating whether James Desborough, the 40-year-old responsible for killing three men in a six-month period, may have been involved in additional deaths. The review comes as officers examine whether his known victims were the full extent of his violence.

According to the available details, Desborough killed two men he had met at a homeless shelter before later killing his prison cellmate. The case has drawn renewed attention because investigators are now looking beyond those three deaths.

Police are also reviewing at least one unexplained case to determine whether there could be any connection. While limited information has been released about that inquiry, the move suggests detectives are trying to establish whether Desborough may have had more victims than previously understood.

The investigation now appears focused on building a clearer picture of his past actions and checking whether any unsolved or suspicious death matches the pattern of the murders already attributed to him. For now, authorities have indicated that the review is ongoing.
