While Stephan Garner admitted to killing Amber, he denied the murder charges. Now, the trial in this case opened in Manchester Crown Court in October 2026, and new details about the incident have emerged. To mention, Stephan Garner, who is 31 years old, has pleaded guilty to manslaughter but not guilty of murder.

In court, prosecutors revealed that Amber was stabbed in the early hours of April 18, 2026, a day before Stephan was arrested on suspicion of murdering his partner. According to the prosecutors, after killing Amber, Stephan spent the next day getting rid of the evidence. In court, it was revealed that Amber was stabbed repeatedly and had at least '32 wounds around her face and neck'.

The prosecutors also mentioned that this shocking incident took place after an argument between the couple. Stephan, following the crime he had allegedly committed, told a close friend that he would clean his bathroom, the place where Amber was found dead, after police forced their way into the flat.

In court, jurors were further informed that Garner wanted Amber to move in with him; however, she felt pressured.
