UC Berkeley Professor Shot Dead in Greece During Custody Visit—Global Academic Community Mourns

The academic world is in mourning after the shocking and tragic death of Przemyslaw “Przemek” Jeziorski, a highly respected marketing professor from the University of California, Berkeley. On July 4, 2025, Jeziorski was gunned down in broad daylight in Agia Paraskevi, a quiet residential suburb of Athens, Greece, during a planned visit to see his two young children amid an ongoing custody dispute. The murder, described by investigators as a "targeted execution," has sent shockwaves through the global academic, Polish, and American communities and sparked an international criminal investigation.

A Tragic End to a Distinguished Academic Life

Jeziorski was a well-known and accomplished scholar in the field of quantitative marketing and industrial organization. His work had received international recognition, and he had been a faculty member at UC Berkeley’s Haas School of Business since 2012. With a PhD in Economics from Stanford University, he was admired not only for his intellect but also for his dedication to his students, colleagues, and academic rigor.

At only 43 years old, Jeziorski was at the height of his career. His research had been cited by hundreds of scholars and was being used to shape marketing strategies, consumer behavior modeling, and data-driven decision-making frameworks across industries. He was known for his humility, kindness, and an unwavering commitment to his students’ success.

But beyond academia, Jeziorski was a father to two young twins and had traveled to Greece specifically to be with them during the summer holidays. It was meant to be a time of bonding and healing. Instead, it ended in a brutal assassination just steps away from their home.

The Shooting: A Calculated Daylight Assassination

On the morning of July 4, Jeziorski arrived in Agia Paraskevi to meet his children. He was near the residence of his ex-wife, a well-known Greek economist, when he was approached by a masked gunman. According to eyewitnesses and initial police reports, the assailant fired at least five rounds from close range, hitting Jeziorski in the chest, neck, and head. The attack occurred around 11:30 a.m., in a calm suburban neighborhood with children playing nearby.

Emergency responders arrived within minutes but could not revive him. Jeziorski was pronounced dead at the scene.

Security footage from nearby homes and businesses captured a masked individual fleeing the scene, possibly getting into a waiting vehicle. Police now suspect the shooter had a getaway driver and that this was not a spontaneous act of violence but rather a carefully orchestrated killing.

Unanswered Questions and Speculation About Motive

Authorities are exploring several theories as to the motive behind the murder. Because Jeziorski was not involved in political activism or business dealings known to provoke such violence, the primary investigative theory is that the killing is tied to an ongoing custody dispute with his ex-wife. The couple had been in litigation over parenting rights, with tensions reportedly escalating in recent months.

However, investigators have not confirmed any link between the custody case and the murder, and no suspects have been arrested. The ex-wife has been cooperating fully with law enforcement and is not considered a suspect. Nonetheless, Greek police are examining the possibility that the crime may have been commissioned or planned by a third party with a personal or emotional connection to the ongoing custody battle.

Another line of inquiry involves possible ideological motives, though no credible evidence of this has emerged so far. Authorities are also investigating Jeziorski’s movements in the days before the murder and have collected electronic devices, including phones and laptops, in hopes of uncovering communications or threats that might point to a motive or suspect.

An Outpouring of Grief from Around the World

The reaction to Jeziorski’s murder has been one of deep sorrow and disbelief. Faculty and students at UC Berkeley were stunned by the news. Many have described the emotional shock of losing not just a professor but a mentor and role model. In statements released by the university, administrators praised Jeziorski’s academic contributions and character, calling his death an “unfathomable loss.”

Students recalled his enthusiasm for teaching, his late-night responses to emails, and his habit of spending hours after lectures helping those who struggled with difficult material. His courses, though academically rigorous, were highly sought after, and his reputation as both a researcher and educator was globally respected.

In Poland, his extended family, former schoolmates, and national media covered his death extensively. A candlelight vigil was held in his hometown, where people shared memories of the “brilliant and kind boy who grew into a man of global stature.”

Family in Mourning, Again

The timing of Jeziorski’s death is particularly cruel: just weeks earlier, he lost his father, a trauma that the family was still processing. Now, the dual blow of losing two generations has left his mother, brother, and extended family in a state of devastation.

His brother, Lukasz Jeziorski, launched a public campaign to raise funds for transporting the body back to Poland and to cover legal expenses related to the case. In heartfelt statements, Lukasz described his brother as a man who “loved deeply, taught brilliantly, and gave selflessly.” The fundraiser has drawn global support from academics, students, and members of the Polish diaspora.

His Children: Orphans of Violence

Perhaps the most painful detail is that Jeziorski’s two young children—twins Zoe and Angelo—have now lost their father in the most traumatic of ways. Reports suggest they were nearby when the shooting occurred. Although they did not witness the act directly, the psychological impact of losing a parent in such a brutal and public fashion will undoubtedly affect them for the rest of their lives.

Child psychologists and social services in Greece are working with the family to provide trauma support. Jeziorski’s family has expressed a desire to stay involved in the children’s lives and is in discussions with Greek authorities about their future custody and visitation arrangements.

A Scholar's Legacy Cut Short

Jeziorski’s academic contributions were immense. His research explored the interface of machine learning and economic theory, with a focus on market structure, competition, and consumer behavior. His publications were not only prolific but impactful, appearing in top journals such as Marketing Science, The American Economic Review, and Journal of Political Economy.

He was also a dedicated collaborator, co-authoring work with other scholars in both Europe and the U.S., and mentoring a new generation of marketing researchers at Berkeley and beyond. His lectures were infused with passion, depth, and humor—a rare combination that made even the most complex theories accessible and engaging.

Beyond his academic output, Jeziorski believed strongly in education as a tool for empowerment. He frequently volunteered for student mentorship programs and participated in outreach initiatives to increase diversity in STEM and business education.

A Violent Trend in Global Academic Spaces

Jeziorski’s murder is the latest in a troubling trend of violence targeting academics, journalists, and other public intellectuals. Whether driven by ideology, personal vendettas, or unresolved legal battles, such acts of violence are increasingly affecting people who dedicate their lives to knowledge and public service.

University campuses around the world have responded by reassessing security for faculty involved in contentious personal or legal disputes. Berkeley’s administration has indicated plans to develop a support system for faculty traveling abroad, especially during personal legal entanglements.

Investigation Continues Across Borders

Greek authorities have launched a full-scale criminal investigation, working with Interpol, U.S. law enforcement, and Polish diplomatic services. Surveillance footage, forensic evidence from the crime scene, and Jeziorski’s personal correspondence are all being analyzed.

So far, no suspects have been identified publicly. The investigation is ongoing, with police urging anyone with knowledge of the gunman or getaway vehicle to come forward. A reward has been offered for information leading to an arrest.

UC Berkeley Plans Memorial, International Support Grows

The Haas School of Business has announced plans to hold a public memorial for Jeziorski in the fall semester. Colleagues and students are organizing a scholarship in his name to support international students pursuing studies in data-driven marketing and behavioral economics—areas Jeziorski helped pioneer.

In addition, international academic societies have pledged to highlight Jeziorski’s research and continue his mentorship models through joint teaching platforms and symposiums.

Conclusion: A Legacy of Learning, a Demand for Justice

Przemek Jeziorski was more than a professor. He was a father, a friend, a scholar, and a role model. His death has left an irreplaceable void in the world of academic research and in the lives of his children, family, and thousands of students who learned from him.

As the investigation unfolds, the hope remains that those responsible for this senseless act will be brought to justice. But justice alone will not ease the pain, nor fill the empty chair he leaves behind in lecture halls, dinner tables, and bedtime stories.

His life, tragically cut short, will live on in the research he published, the minds he shaped, and the love he gave to those around him. His name now joins the tragic list of scholars who were taken from the world not by illness or age, but by violence—a reminder that even the most enlightened among us are not immune to humanity’s darkest instincts.
