A woman appeared to brag on Facebook that she had chosen a new, better dad for her kids just weeks before she allegedly got her new boyfriend to kill her ex-husband.
Nadia Michelidaki, 43, and her boyfriend Christos Dounias, 35, were arrested this week for the shooting murder of UC Berkeley professor Przemyslaw Jeziorski in Greece.
Jeziorski was shot five times in broad daylight in Athens on July 4 near his ex-wife’s house. He was visiting the country to visit his two children and attend a family custody hearing.
Back in May, Michelidaki shared an AI image showing a man in a suit looking unhappy and surrounded by money. Next to him, another man is seen smiling as he holds a fishing rod and hugs his son.
Michelidaki tagged her new boyfriend and wrote: ‘When you realize that you picked the best dad for your kids.’
The alleged killer and the beloved professor had been going through a nasty custody battle when Jeziorski was killed, according to police.
Greek authorities said Michelidaki and Dounias planned the murder, and that Dounias was the one to pull the trigger as Jeziorski arrived to pick up his children.

Two Albanians and one Bulgarian were also arrested in the case. They are accused of providing the murder weapon and transporting the gunman.
Michelidaki’s lawyer told CNN she denies any involvement in the murder.
Meanwhile Greek media reported that Dounias confessed to the murder and said his girlfriend was the mastermind.
Jeziorski and Michelidaki married in 2014 and he filed for divorce in 2021. They founded a rental property management company and were apparently also battling over finances.
The professor had sought a restraining order in San Francisco against his ex-wife in May, saying he feared for his life, before he was killed, as reported by the San Francisco Chronicle.
He accused Michelidaki of threatening and exhorting attempts and said Dounias assaulted him twice – once knocking his phone out of his hand and later the dame day kicking and pushing him.
Dounias was charged with assault over the May incidents.
‘She made me afraid of my life by having her partner, who is hostile and aggressive towards me, (present) during the visitation exchange, despite my asking her not to do so,’ Jeziorski wrote.
Jeziorski also claimed his ex-wife had been sending him messages on Slack demanding co-authorship on his research and ‘threatening to “contact my colleagues and the dean of my department if I did not pay her money.’

The professor added he believed Michelidaki was trying to ‘humiliate me socially in order to control me.’
‘Although I know her threats are baseless, I am still intimidated by her actions,” He wrote. ‘Her baseless allegations will harm my economic prospects for employment and completely damage my reputation in the intellectual community, regardless of their truth.’
After the murder, the professor’s ex-wife said she did not know of anyone who would want to harm him.
‘Przemek loved his children and fought for them until the end. He paid the heaviest price, unnecessarily, for this,’ the professor’s family said in a statement.
‘This summer, he wanted to bring his children to his hometown of Gdynia, Poland. This death and the circumstances surrounding it remain impossible for us to accept, but we find some measure of comfort knowing that progress is being made toward justice, and that the kids are about to reunite with their family into a safe environment.’

The former couple’s two young children are now in the care of Greek child custody.
‘Przemek’s ten-year-old children, who are US and Polish citizens, are now under care in accordance with Greek child custody procedures,’ Jeziorski’s brother Lukaz said in a statement.
‘Our primary concern is their safety and wellbeing, and helping them reconnect with their family to minimize the trauma they have already endured.’
Jeziorski studied at the SGH Warsaw School of Economics, the University of Chicago, the University of Arizona and Stanford University, where he got his PhD in Economic Analysis and Policy, according to his website.
He previously taught at Johns Hopkins University and was a research intern at Microsoft as well.
He’s published in numerous ‘top-tier academic journals,’ and mentored more than 1,500 MBC and PhD students during his teaching career.
He was also a co-founder of Keybee, a start-up for UC Berkeley’s Skydesk, ‘that provides a data-driven solution to managing thousands of short-term rentals,’ including popular sites like Airbnb, Vrbo and Booking.com.
Jeziorski also consulted with many big-name companies, including Microsoft, Mastercard, MIC Tanzania, and more.
He lived in a $830,000 one-bedroom, one-bathroom high-rise condo in San Francisco, according to public records.
