Joseph Efe, a 30-year-old artist, revealed that his intention was to steal his victim’s phone, not to kill her. He admitted to psychologically manipulating and instilling fear in his targets, claiming he never used weapons but made them believe he wasn't acting alone. Efe was caught when hotel staff were alerted by Olivia's screams. The Nigerian Security and Civil Defense Corps (NSCDC) paraded Efe, with Commandant Olusola Odumosu stating that Efe confessed to being a fraudster (Yahoo Boy) targeting women on dating sites.
