The ex-wife of a UC Berkeley professor who was gunned down by a masked assailant in a suburb of Athens Greece earlier this month has been arrested for arranging his killing, according to a Greek media report. Przemyslaw Jeziorski, a 43-year-old professor of marketing at the UC Berkeley Haas School of Business was visiting his children in the Athens suburb of Agia Paraskevi when he was shot and killed in broad daylight on July 4.

The masked shooter reportedly shot Jeziorski five times. According to Greek newsletter Tovima, the native of Poland was walking to his ex-wife’s home to see the couple’s two children, who are twins.

According to Tovima, Jeziorski’s ex-wife has been arrested and charged with convincing her current partner to kill Jeziorski in a “gangland-style” shooting. Three other men, two Albanian nationals and a Bulgarian man, have also reportedly been arrested in connection to the case.

Greek police, according to Tovima, say the three foreign nationals transported the alleged shooter to the scene and provided him with a Tokarev model automatic handgun — the alleged murder weapon.

Jeziorski, who had been a faculty member of the Haas School of Business since 2012, was reportedly declared dead at the scene.
