You also need to be discussing with your attorney or a family law attorney whether your state has laws against abuse of POA, which is possibly what happened here, or elderly financial abuse.
How much were the insurance policies worth and how much were the beneficiaries left in the will?
Your attorney will need to contact the insurance company to find out whether the guardian used power of attorney to submit a beneficiary change designation form to change the designated beneficiary to HIS name, which may be illegal. If this happened your attorney may need to sue guardian for breach of fiduciary duty or theft to get these monies returned to the estate.
