Teacher Goes on First Date and Is Never Seen Again
Teacher Goes on First Date and Is Never Seen Again
A 23-year-old teacher met a man online for a first date in East London and never returned home. Unbeknownst to her, the man was known to five separate agencies as a serious risk to others, yet none of them warned her.
In this episode, we analyze the tragic disappearance of Katie Lock, a vibrant history and politics teacher, and the systemic failures that allowed a dangerous individual to connect with her. How could a man with a documented history of threats walk free and meet someone through an online dating platform?
