Przemyslaw Jeziorski, who taught quantitative marketing at the Haas School of Business, was shot several times on July 4 outside Athens, the authorities said.

Police in Greece are searching for the killer of a University of California Berkeley professor who was shot and killed on July 4 while visiting Athens to see his children and attend a family custody hearing.

Greek officials say the broad-daylight attack came one day after a custody hearing over the victim's 10-year-old twins.
