ORLANDO, Fla. -

Orange County deputies have named two persons of interest on Monday in the Orlando restaurant shooting, killing an employee at the restaurant last month.

Raymond Barnes Jr., 22, and Calvin Washington, 20, were named the persons of interest in the shooting, which killed 53-year-old Ying Sun, also known as Anna.

Deputies say she was working at the China Wok on Silver Star Road when a gunman stormed into the restaurant and shot her after deputies say she didn't understand him. She died at Orlando Regional Medical Center. Authorities haven't made any arrests in the case.

Deputies released surveillance images of the gunman last month. Neither of the men have lengthy criminal records. Barnes was once arrested for burglary, but those charges were dropped. Washington also has a few minor offenses.

Deputies are asking for the public's help in finding the men. Contact police if you have information on their whereabouts.
