Woman Tracks Aunt’s Killer via Facebook, Leads South Africa Arrest

Lehanne Sergison, a retired chartered surveyor from Bromley, took extraordinary measures to bring justice for her aunt, Christine Robinson, who was raped and murdered in South Africa in 2014. After police failed to capture the suspect, Andrea Imbayarwo, who fled the country, Sergison devised a plan to lure him through Facebook by creating a fake profile and engaging him in conversation. Over two and a half years, Sergison's online 'honey trap' led to the discovery of Imbayarwo’s whereabouts, ultimately resulting in his arrest and life sentences in 2022. Despite initial police failures and multiple botched operations, Sergison's relentless pursuit and the viral social media campaign she initiated played a crucial role in securing justice. Her efforts were carried out entirely from the UK, without visiting South Africa, and are the focus of the Amazon Prime documentary "The Facebook Honeytrap: Catching A Killer." The case highlights the challenges in cross-border justice and the lengths a determined family member went to ensure accountability.
