All five individuals arrested for the murder of a 43-year-old UC Berkeley professor earlier this month on Monday were ordered held on remand, including the victim’s ex-wife.

Under Greece’s legal system, a suspect is ordered jailed in a felony case pending trial or the continuation of the ongoing investigation when both an investigating magistrate and relevant prosecutor agree over a remand. The maximum period allowed for a pre-trial remand in Greece is 18 months, although a suspect can petition a judicial council for release.

Przemyslaw Jeziorski, 43, known as Przemek or “PJ, was gunned down in broad daylight in the northeast Athens district of Aghia Paraskevi as he was walking to pick up his two children, a twin boy and girl, 10.

The murder and the subsequent arrest of his ex-wife, her boyfriend and three accomplices has generated widespread international scrutiny. Among others, media reports on Monday claimed that the 35-year-old boyfriend, who has allegedly confessed to shooting Jeziorski, told police during the initial interrogations that he “did it all for” his companion. Media reports citing “leaked police confessions” also maintain he was concerned that Jeziorski would take the two children abroad permanently and that he wanted to “protect my family”.

All five suspects provided sworn testimony throughout Monday, with the woman’s lawyer maintaining that she did not know of the plan to kill her ex-husband, business partner and the father of her two children.

The same reports had the victim’s ex-wife denying any knowledge of the crime, while maintaining that Jeziorski financially supported her and their two children and that she had no incentive to kill him.

She and the victim had been involved in a bitter custody battle over the children and, according to other reports, feuded over an online business they had founded.

The trio of alleged accomplices – two Albanian nationals and a Bulgarian – include a 16-year-old.
