Video footage of Ivan Esack admitting to police that he murdered Natalie Esack. Evil Ivan Esack, 38, plunged an eight inch kitchen knife into pretty Natalie Esack, 33, 11 times at her hairdressing salon because he was so jealous of her new lover. The ex Kent Police detective-turned-phoney football agent bought the kitchen knife at Sainsbury's supermarket in Ashford, Kent. He then went to Natalie's nearby salon, Esack Hair Design, where he trapped her in the basement and attacked her with such ferocity the tip of the blade broke off. The former Detective Constable then calmly left the salon saying "she deserved it, the bitch" before returning to his car and paying for his parking. He admitted manslaughter but denied murder on the grounds of diminished responsibility because he was suffering from mental illness. But a jury of eight men and four women at Maidstone Crown Court found the him unanimously guilty.
