Sympathy For A C0-Worker's Death

Dear ___________________

I was just informed by our office manager of your _____________________ death.  It is impossible to adequately express my sincere sympathy at this most difficult time.

I had worked very closely with ____________________  in the office.  Therefore, I feel that I have lost a very good friend as well as a fellow co-worker.

Please let me know if I can be of any help to you.

Sincerely,
