You could say something along the lines of "Colleagues, I've been asked to let you know that X's relative died at the weekend (or whenever).  We're writing formally to X to express the company's condolences."  That should do the trick.  It informs everyone appropriately and gives people an opportunity to send their own condolences to the bereaved person.  

Best wishes,
