BOCA RATON, Fla. (AP) — Police are searching for four suspects they say robbed a Boca Raton restaurant, terrorized patrons and fatally shot the bartender.

Authorities said upscale Josephine’s restaurant closed at 10 p.m. Friday night, but the owner, several employees and diners remained.

Bartender Rafael Rodriguez and a waiter went out back when authorities said four armed men with face masks knocked them to the ground. The waiter was allegedly pistol whipped.

Police said the suspects then entered the restaurant and stole wallets, jewelry and cellphones from diners. As the robbers were leaving, Rodriguez exchanged words with one of the suspects. The Palm Beach Post reports Rodriguez was shot once. He died at the hospital.
