The husband of a University of Suffolk lecturer accused of her murder told neighbours “I think I’ve killed my wife”, a jury has heard.

Wednesday marked the second day in the trial of Ertan Ersoy, who is charged with the murder of Dr Antonella Casteldevere by stabbing her in the throat.

A witness told the court how they had been watching TV at home when they heard loud shouting from a nearby house in Wickham Road, Colchester.

After going outside, the witness asked a man – who was running across the road – if everything was alright, but he replied ‘no, someone is hurt’ and pointed at Ertsoy’s address.

The witness then said they rushed towards Ertsoy’s house and found the 51-year-old inside, bleeding heavily from two cuts to his stomach.

They explained: “I remember he was in the living area near the door to the kitchen – he told me, ‘I think I’ve killed my wife’.

“He was concerned about his wife; he was saying ‘my wife, my wife’ – he said that a few times.”

As the witness recounted the incident, Ersoy – who was dressed in a suit and tie, accompanied by a translator – appeared to break down in tears and held a tissue to his face.

The witness then continued by saying that after they helped treat Ersoy’s wound, they went into the kitchen to see if anyone else had been hurt, whilst a second neighbour who had also rushed to the address stayed with Ersoy.

“The door to the kitchen was partially open and I could see someone lying on the floor; I was pushing against the solid door trying to get in.

“I was trying to get in but I was met with some resistance – [Dr Casteldevere] was lying on the floor.

“She wasn’t moving – it was almost like there was a halo of blood behind her on the floor.”

The witness then told the court how she performed CPR on Dr Casteldevere, but couldn’t work out where the blood on the floor had come from.

“I started to hear sounds coming from her and at first I didn’t know where they were coming from, but I then noticed they were coming from her throat area.”

Prosecutor Christopher Paxton, KC, asked: “Did you then notice a cut to [Dr Casteldevere’s] throat?” to which the witness replied “yes”.

The witness then said they returned to the living room to make sure Ersoy was still applying pressure to the two cuts in his stomach.

“He asked ‘my wife?’, and I just shook my head at that point – we didn’t speak about anything else.”

The trial continues.
