Stimpson, 26, was described as “rather demanding”, with Ms McLaren often trying to “put things right”. He himself said he had “intense emotions”.She finally ended the relationship on June 17, 12 days before she died.In the intervening days, the warehouse worker posted photos and derogatory comments on Facebook about the University of Kent student and part-time barmaid.Ms McLaren had blocked Stimpson on social media, but learnt of his comments and reported the posts to police on June 22. The previous day, Ms McLaren had told a relative she feared Stimpson would hurt her. Describing him as “manipulative and turning nasty”, she said: “I am actually scared about what he might do. I’m scared he might hurt me. I don’t know how on edge he is.” Joshua Stimpson pictured on CCTV purchasing a knife, that was shown to the jury at Maidstone Crown Court Credit:Kent Police/PA During the killing, Benjamin Morton, a witness, tried to pull Stimpson off Ms McLaren as she screamed.Mr Morton later told police Stimpson was “continuously” stabbing Ms McLaren, mainly in the neck area. He added: “It was like a frenzy, he was doing it again and again.”Ms McLaren, who studied sport, exercise and health, had just been to a gym. Stimpson had been at the same gym and she asked him: “Are you following me now?” She also sent a WhatsApp message to a group of friends at 11.02am, saying: “Feel like I’m f—— looking over my shoulder all the time”. It was her last communication.Prosecutor Philip Bennetts QC said as she walked to her car, CCTV footage showed Stimpson waiting for her in his vehicle and then begin to tail her. He left his car, walked quickly to hers and yanked the door open as Ms McLaren screamed. Stimpson, who admits manslaughter but denies murder, was arrested at the scene, covered in blood. The court heard he had told a work colleague he suffered from bipolar disorder.Two days before the killing, Stimpson bought a Sabatier paring knife from an Asda store in Chatham. It was found on the driver’s seat of Ms McLaren’s car after she died. Police also discovered a pick axe in Stimpson’s car. The trial continues.
