You should write the letter in very kind and supportive words so that it can give comfort to the grieving person. Here is the sample of condolence letter which is written on death of friend to his sister.

Dear Ms. Suzanne
It is really unpleasant to know about the untimely death of your brother Mr. Greg R. Jones. He was a good friend of mine and was working in same office with me. He was very hard working and helping person and had very good impression on every one in office.
I was really very shocked when I got this news but we have to accept the reality about death of Mr. Greg. It’s all God’s wish and I will pray to God to give strength to you and his family to move forward in life without him.
Please accept my deep condolences on this unpleasant incident. I am trying to complete all the official formalities after death of employee. Please tell me if you want any other help.
