Przemyslaw Jeziorski, a tenured professor at the University of California, Berkeley’s Haas School of Business, was fatally shot on July 4 on the outskirts of Athens, Greece. He was 43.
Greek and international authorities are investigating his death as a homicide.
“I am heartbroken by news of the tragic and sudden death of Professor Przemyslaw Jeziorski, a beloved member of our marketing faculty and Haas community,” dean Jenny Chatman of UC Berkeley Haas said in a statement released by the school. “While authorities are investigating what happened, our focus is on supporting our community during this difficult period. My heart goes out to Przemek’s family and loved ones. We will miss him.”
Police in Greece have not announced any arrest and have released limited information about the ongoing investigation.
Based on reports from Greek media, Jeziorski traveled to Greece for a custody hearing and was gunned down in Agia Paraskevi, a suburb of Athens, just near his ex-wife’s residence. He reportedly had gone to meet their children when the shooting occurred in broad daylight by a masked gunman who opened fire multiple times, fatally striking Jeziorski in the chest and neck.
A father of two, Jeziorski held the Egon and Joan von Kaschnitz Distinguished Professorship in Business Administration. During his 13 years at UC Berkeley, he taught more than 1,500 MBA and Ph.D. students, with a focus on data analytics, marketing science, and industrial organization.
His death has drawn expressions of grief and outrage from colleagues, former students, and members of the global academic community.
‘Senseless tragedy’
Professor Zsolt Katona, who helped hire him into the Haas Marketing Group in 2012, said, “It’s hard to come to terms with this senseless tragedy. He was an amazing person, friend, and colleague. He was a loving father of two young children and always there if someone needed help. He had great influence on the marketing field not only through his research but through his energetic presence and optimism combined with a healthy dose of skepticism.”
Jeziorski was born on April 24, 1982, and grew up in Gdynia, a city on Poland’s Baltic coast. His younger brother, Lukasz Jeziorski, described their relationship as extraordinarily close. “We were like twins. We understood each other without words,” he said.
In a public statement posted to a fundraising page on the Dutch platform WhyDonate, Lukasz Jeziorski said, “My brother, Przemyslaw (Przemek) Jeziorski, was tragically killed in Athens on July 4, 2025. He was the victim of a terrible crime, and the perpetrator is still at large. Our family is heartbroken, and we are doing everything we can to ensure that justice is served.”
“… He was an amazing person, friend, and colleague. … He had great influence on the marketing field not only through his research but through his energetic presence and optimism combined with a healthy dose of skepticism.”

“To pursue legal action and support ongoing investigations, I have secured legal representation in Greece and will also need support for future legal processes in Poland and the United States,” he wrote. “These efforts come with significant and urgent costs that my mother and I cannot manage on our own.”
“We are asking for your help to raise funds for legal fees, the repatriation of Przemek’s remains to Poland, and related expenses,” his statement continued.
As of Wednesday afternoon, more than 54,000 euros, around $60,000, have been donated to Jeziorski’s family.
