A University of California, Berkeley professor was shot and killed by a masked gunman while visiting family in Athens, Greece, reports said.

On July 4, Przemysław Jeziorski, a 43-year-old associate professor of marketing at UC Berkeley’s Haas School of Business, was tragically killed. He was shot five times at close quarters in a suburb of Athens, sustaining wounds to his chest and neck, according to a report from Polish website TVP World citing media sources. 

According to Greek news source Ta Nea, at the time of the incident, Jeziorski was on his way to collect his children from his Greek ex-wife, who resides nearby. The report noted he was in Greece to attend a court session concerning child custody. 

“I am deeply saddened by the heartbreaking and unexpected loss of Professor Przemyslaw Jeziorski, a cherished member of both our marketing department and the Haas community,” said Jennifer Chatman, the dean at UC Berkeley’s Haas School of Business, to The Daily Californian student newspaper. While authorities continue to investigate the circumstances, our main priority is offering support to our community during this challenging time. My thoughts are with Przemek’s family and loved ones. He will be dearly missed.”

“Our family is heartbroken, and we are doing everything we can to ensure that justice is served,” he added. “We are asking for your help to raise funds for legal fees, the repatriation of Przemek’s remains to Poland, and related expenses. Przemek was a loving father to two young children and a beloved professor at the Haas School of Business at UC Berkeley.”
