A man who murdered his wife at their home in Colchester has been sentenced to life imprisonment thanks to work by specialist officers and staff. Ertan Ersoy was convicted yesterday (Thursday 26 October) of killing 52 year-old Antonella Castelvedere at an address in Wickham Road at around 11.15am on 1 June last year. Initially Erosy, 51, claimed he had killed her in self-defence and raised a defence of diminished responsibility. He maintained the injuries he had been found with had been inflicted by Antonella but there wasn’t any independent evidence to suggest they had been caused by her. As our officers investigated, they established that Ersoy had attempted to control his wife’s life in the months leading up to her murder, and used listening devices to record her conversations. The jury at his trial heard the incident on 1 June was the ‘ultimate act of control’. The jury at his trial heard the incident on 1 June was the ‘ultimate act of control’.
