A Salisbury Tesco worker accused of murdering his wife and daughter believed the two of them were sleeping with the same man, a court heard.

Marcin Zdun suspected his wife Aneta, 40, to be cheating on him with one of his colleagues.

UPDATE - Jury finds Zdun guilty of murdering wife and daughter

Today, December 15, jurors heard that the 40-year-old claimed his eldest daughter Nikoleta, 18, was also having sex with him and for that he felt “upset” and “ashamed”.

Zdun is standing trial at Winchester Crown Court following the death of both Aneta and Nikoleta at their home in Wessex Road, Salisbury on June 1.

The father of three has previously pleaded not guilty to two counts of murder.

Although he accepts killing the pair, he claims to have “no recollection of what he did that afternoon”.

Marcin Zdun murder trial so far

‘The deal’

Giving evidence before the jury assisted by a Polish interpreter, Zdun admitted pushing Aneta to the ground on April 3 but denied strangling her, saying: “I shook her a bit on the floor”.

“It wasn’t a serious incident. Nothing happened to anyone,” he added.

However, prosecutor Nicholas Haggan QC told the court about a conversation with his brother in law two days before the killings in which Zdun was worried about the “evidence” Aneta had against him because “I wiped her around a bit on the floor”.

Nikoleta wanted to call the police but Aneta persuaded her not to, jurors heard.

Addressing the defendant, Mr Haggan said: “The deal was that you would leave [the family home] and they wouldn’t report you to the police”.

“Yes,” replied Zdun.

Affair suspicions

After moving to Rawlence Road, the Tesco worker admitted telling his landlord that Aneta was “too sexually open with Nikoleta”.

The court heard Zdun believed both his wife and daughter were having sex with his former colleague Martin Punter.

“I felt very sad about this, I felt ashamed, I felt upset,” he told the jury but denied feeling angry.

Mr Punter previously told the court he did not know Aneta.

‘I was in shock’

On the afternoon of June 1, Zdun walked to Wessex Road carrying a knife, almost £1,000 and his passport.

On his way there, he stopped to buy some beer before then entering the gate of the family home.

The court heard Zdun doesn’t remember what happened there, the next thing he knows is someone was sat on his back in the street.

He told the jury: “I was in shock” but couldn’t explain why.

After being arrested, Mr Haggan told the court Zdun refused to confirm his name and nationality and refused to speak because he didn’t have a solicitor.

Asked why he requested a solicitor, Zdun said: “I don’t know”.

Addressing the defendant, Mr Haggan added: “You knew exactly what you did, didn’t you? That’s why you wanted a solicitor and that’s why you were keen to tell the police you felt mentally incompetent. You were setting up your defence, weren’t you?

“I don’t know,” he said.

The trial continues.
