According to Poynter:

The marker will bear the Star of David and a Hebrew prayer, “Hear O Israel, the Lord our God, the Lord is One.” It also will be inscribed with the last words of journalist Daniel Pearl before he was murdered by terrorists in 2002: “My father is Jewish. My mother is Jewish. I am Jewish.”

Koch died on the 11th anniversary of the murder of Pearl.

Update

I managed to misspell “Daniel”. Profuse apologies.
