A Tesco worker accused of murdering his wife and daughter in a jealous rage told a court he believed his wife was having an affair and his daughter was covering up for her.
Marcin Zdun, 40, is charged with the murder of Aneta Zdun, 40, and 18-year-old Nikoleta Zdun.
The women were found seriously injured at their home in Wessex Road, Salisbury, Wiltshire, on June 1 this year and pronounced dead at the scene.
The defendant told Winchester Crown Court that he believed his wife, a care worker, had been having an affair with a man he worked with.

He said that he suspected this man because of ‘the way he was looking at me, this piercing look and anger in his eyes’, and he believed he had put a bug on his phone with the help of a friend.
He said he and his wife were sleeping in separate rooms ‘because she didn’t want to have sex any more. I thought she maybe had someone on the side’.
He added that he believed his daughter was ‘covering up’ for his wife, who would go out in the evenings without saying where to.
Zdun also said that his wife was not helping to tidy the house or make family meals, despite only working three days a week.
Marcin Zdun killed his 18-year-old daughter Nikoleta and wife Aneta, 40, ‘in the most brutal fashion’
He said he put videos of the ‘untidiness’ on Facebook, as well of mouldy soup in the fridge, to show people who would not believe him.
He said he did not have the ‘strength’ to do the housework himself because he worked night shifts.
The Tesco worker said that this led to arguments between him and his wife and he also argued with his daughter after she wanted to have face piercings.
Speaking through an interpreter, the Polish national said: ‘I didn’t let her do many things, I didn’t let her have a tattoo done and piercings, but her mum would have let her do everything anyhow, so she still had them done.’
He continued: ‘They were just keeping together, they would just laugh at me, they were doing whatever they wanted.
Nikoleta was a college student who was passionate about fashion and make up and dreamt of one day working abroad. She had been studying travel and tourism.
‘They didn’t do anything around the house, they would just go out whenever they wanted, I didn’t know where they were going, for my own peace, that they weren’t going out meeting some guys.’
He added that his wife and daughter were ‘spending my hard-earned money and they were laughing in my face’ and he felt ‘harassed and abused in my own home’.
Zdun is accused by the prosecution of having a ‘controlling nature’ over his family.
Nicholas Haggan QC, prosecuting, has told the jury that the defendant does not deny he killed his wife and daughter, but had no recollection of the incident.
When Zdun was arrested at the scene of the killings, police found a folding lock knife in his trouser pocket with blood stains on the blade and handle, the court has heard.
Winchester Crown Court heard how Zdun ‘butchered’ Aneta and Nikoleta after his wife kicked him out of the family home.
A workman who witnessed the alleged murders said ‘there was no humanity’ and ‘pure anger’ in Zdun’s face during the attack in Salisbury, Wiltshire, on June 1.

Another hero workman who chased Zdun and wrestled him to the ground until police arrived told Zdun’s murder trial: ‘I punched him but I wish I did more’.
Painter and decorator David Powell rushed to the scene when he heard screams from Zdun’s young children, who were inside when it unfolded.
Mr Powell became emotional as he described in graphic detail how Zdun ‘butchered’ his wife and daughter with a six-eight inch knife.
‘There was no humanity in his face whatsoever, just anger – pure anger. I don’t know how you can do that to another human being’, Mr Powell said.
‘His sole purpose was to kill them… he just went mental.’
Mr Powell, who was just feet away from the attack, said care worker Aneta tried to protect her college student daughter by standing between her and Zdun.
Mr Powell teared up as he said he couldn’t save the women. ‘There was nothing I could do’, he added.
Mr Powell said Zdun then collected his bag and ‘casually walked down the street like nothing happened’ but started running when he and his colleague chased and detained him.
Neighbour Tamar Vellacott told the court: ‘A workman came up covered in blood, he said ‘I did what I had to do, I punched him, but I wish I could have done more’.’
Zdun denies two charges of murder and the trial continues.
