Executor of will stold the money left by the deceased, what can I do about it?

i'm sorry this has happened to you.  You can file a complaint in the court of the county in which the will was probated.  Ask to have the executor removed, and claim breach of fiduciary duty.  you may be able to track down the funds that were stolen, or put liens against things that were purchased with the funds.  If the executor was required to post a post, you can file a claim against the bonding company.
