A DAD who allegedly killed his wife and daughter told cops he was “allergic to lies and cheating” after his arrest.
Tesco worker Marcin Zdun is accused of killing 18-year-old Nikoleta and Aneta, 40, just weeks after his wife kicked him out of their home in Salisbury, Wiltshire.
Aneta had told him she wanted a divorce.
The court heard Zdun complained that his wife and daughter were “like best friends” and he was jealous of their relationship and felt they were “pushing him out of the marriage”.
He had also wrongly convinced himself that his wife was having an affair with one of his colleagues.
Zdun had even begun taking pictures of the man without his knowledge.
In text messages, his daughter said he was “not right in the head” and Aneta warned him that he was “making things up and believing them”.
On June 1, Zdun walked to the family home and slit both their throats with a kitchen knife.
Officers who arrested Zdun said he was “covered head to toe” in blood stains but appeared ‘calm’ despite having just killed his daughter and wife of 20 years.
Today, Winchester Crown Court heard that when Zdun arrived at the police station he was asked if he was allergic to anything.
He replied: “Yes, to lies and to cheating.”
Today, the court also heard fragments of conversation recorded by Zdun at the family’s home in the month before he died.
In the recordings Aneta told him was “sick of the accusations, harassment and bullying”.
She said he “bullied” her for “so many years” and he “needed to get treatment” as he had been “making things up in his head” and believing them.
Zdun was overheard asking his two youngest children, who cannot be named for legal reasons, about whether Aneta spoke to “men on the phone”.
In text messages to her mother in the month before she died, Nikoleta said: “He is not right in the head. Tell him not to call in my presence because he is constantly trying to let [the younger children] out or egg them on.”
Her mother told her not to talk to him and said she would speak to him later.
Later on that day Aneta told Zdun: “You are [sick] in the head”
Mr Nicholas Haggan QC, prosecuting, previously told the court Zdun told friends that Aneta was having an affair with a man called Martin Punter, who worked at Tesco with Zdun. Mr Punter never met Aneta.
The officer in charge of the case Angela Bruffell, said they had trawled through all of Aneta’s electronic devices and found ‘no evidence whatsoever’ she was having an affair.
In the weeks before the killings, Zdun also talked to his landlady about his relationship with his wife. He told her that he did not miss her and she was “being too sexually open” with Nikoleta.
Previously Aneta’s father revealed his daughter had told him she was terrified of her husband in the weeks before her death and he had threatened “to kill them all”.
A pathologist revealed Nikoleta and Aneta, a carer for vulnerable people, were left with “catastrophic” and unsurvivable injuries.
Zdun denies two counts of murder but admits killing the pair, “conveniently” claiming he has no recollection of the incident and killed them by way of diminished responsibility as he is mentally impaired.
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.
Her mother Aneta was a physiotherapist as well as a carer at a home care service in Salisbury and treated vulnerable people.
The Zdun family were originally from Tarnow in Poland.
The trial continues.
