Bryan Kohberger this week  escaped execution by firing squad by sensationally changing his plea to guilty of the murder of four students as they slept in their beds in Idaho in November 22. But why the PHD Criminology student, from a different University, picked on these particular victims is still a mystery as he’s refused to explain a motive. In this episode, Professor of Criminology David Wilson, who has met Kohberger’s tutor, analyses whether classroom teachings were behind the killings and reveals that he has to censor some details from students who are worryingly over keen on the mechanics of serial killers. We also look at developments with Lucy Letby and consider six days of jury deliberations in the Beef wellington killer trial.
