Leanne Meecham is stabbed multiple times at her house in Southend on sea in February 2014. The killer is her stepfather and former lover Simon Meecham. Simon was married to Leanne’s mother before embarking on the six-year relationship with his step daughter in 2007. The relationship was abusive from the outset with the Police being called on several occasions. Leanne’s sister Carly Bush and her best friend Alex Speight tell us about their deep sense of loss and former Detective Superintendent David Swindle psychologist Emma Kenny look at Meecham's’ controlling and obsessive behaviour and what drove him to murder Leanne.
