You should contact a probate lawyer as soon as possible. From what you write, it appears that your father's estate has not been settled in court. Because he did not leave a will, someone needs to file an application to administer his estate. The application needs to be filed in the probate court in the county where your father died. The administrator's responsibilities will be to gather your father's assets, pay his final debts, and distribute whatever is left to his heirs.
A probate lawyer can explain the requirements for being appointed administrator, and the costs involved. After you are appointed, you can take control of your father's property, include the home and bank account. If the "caregiver" has no legal right to remain in the home, you will be able to file an eviction. If she has taken control of money or property that she has no right to, you may be able to file a lawsuit to recover the property. You can only do these things after you are appointed.
