who is the killer in murdered soul suspect
Murdered: Soul Suspect Following the evidence, Ronan returns to the museum to discover that Rex is the Bell Killer, having been possessed by Abigail. As he prepares to hang Joy, Ronan manages to force Abigail's spirit out of Rex, and the pair battle by inflicting painful memories on each other. These memories reveal that Abigail has possessed many people to carry out the Bell Killer murders before killing the possessed themselves. Among the possessed are Baxter, who she used to kill Rose, and Ronan, who killed Sophia.
And Then There Were None In the confession, Justice Wargrave writes that he has long wished to set an unsolvable puzzle of murder. His victims would be of his choosing, as they were not found guilty in a trial. He explains how he tricked Dr Armstrong into helping him fake his own death under the pretext that it would help the group identify the killer. He also explains that he replaced the chair in Vera's room. Finally, he reveals how he used the gun and some elastic to ensure his own death matched the account in the guests' diaries. Although he wished to create an unsolvable mystery, he acknowledges in the missive a "pitiful human need" for recognition, hence the confession.
