The man accused of murdering a 'beloved' University of Berkeley professor in Greece allegedly told police he 'did it all' for the victim's ex-wife — who he was dating, according to reports.
'I did it all for [her] and our children so that we could have a normal life without problems,' the still unidentified suspect told Greek police after his arrest, according to an interrogation transcript obtained by CNN.
The suspect is accused of gunning down 43-year-old Przemyslaw Jeziorski — the ex-husband of his girlfriend — as he was arriving at the woman's Athens home on July 4 to pick up their two kids amidst an ongoing custody battle.
3 Przemyslaw Jeziorski, 43, was gunned down outside his ex-wife's home in Athens on July 4.
Jeziorski — a Berkeley Haas School of Business professor — was shot five times in the chest and neck at point blank range by a masked gunman, and was declared dead at the scene.
His ex-wife's boyfriend was arrested 12 days later, and reportedly told police he decided to kill the professor more than a month before.
'A month and a half ago I made the decision to end this torment we were experiencing once and for all,' he told police in the leaked interview transcript.
'We were afraid that he would end up taking the kids completely. That would completely finish off [my girlfriend], who was overly fond of them,' he continued. 'This summer Przemek wanted to take the children and take them to America. But [my girlfriend] did not agree and so she went back to court with Przemek.'

Jeziorski had just scored a victory in the custody fight, with a judge ruling only a day before the murder that he could take his kids for a month
The suspect decided it was a 'good opportunity' to kill Jeziorski when he came by his ex's house to pick up the youngsters, he allegedly told police.
'I approached him and shot him a few times, but I don't remember how many times,' the suspect allegedly admitted.
He even bought the pistol a month earlier, and recruited three friends to help him with the crime.
But those alleged accomplices — who were also arrested — said they had no idea the suspect was plotting murder, and that they'd only been told they were going to help scare and intimidate Jeziorski.
The ex-wife was arrested over the killing, while the shooting suspect's attorney told CNN she knew nothing of the plan — but that they were both afraid Jeziorski's supposed alcoholism was going to put the kids in danger if he won custody.
'My client had come to me in the past to seek advice. He had said his partner's ex-husband had serious alcoholism issues and that he and the mother were worried about allowing access to the kids. He wanted to see if there was something he could legally do about limiting access,' the lawyer said.
Jeziorski's friends and family, however, have refuted any claims that he struggled with alcohol, according to CNN.
3 Jeziorski taught at Berkeley's Haas School of Business for eight years. He and his ex-wife were divorced in 2021.
He and his wife married in 2014, but filed for divorce in 2021.
She is a Greek national and returned home in 2020. But he taught school in California, and the custody battle over their two children was rife with complications over what country the kids would be raised in.
The ex has also denied any involvement in the killing.
But Jeziorski had reportedly been fearful of her and her new boyfriend for months — even requesting a restraining order in May with complaints that he was scared for his life, according to ABC News.
'I am fearful of what she is doing now and what she will attempt to do next as we move forward in this divorce,' he said in the request, which was ultimately denied in a California court.
Jeziorski spent eight years teaching at Berkeley, where colleagues recalled him as an 'outstanding scholar.
'Our family is heartbroken, and we are doing everything we can to ensure that justice is served,' his brother, Lukasz Jeziorsk, wrote on the crowdfunding website WhyDonate.
The kids — twins — are currently under the care of Greek child services, he explained, but he said he would seek to adopt and raise them.
'Przemek was a loving father to two young children and a beloved professor at the Haas School of Business at UC Berkeley,' the brother added. 'He was a leading scholar in marketing science, industrial organization and data analytics. He loved teaching and sharing his passion for the intricacies of marketing analytics and marketing science with his students.'
