(2) Grant the public administrator access to a safe-deposit box rented in the sole name of the decedent for the purpose of inspection and removal of any will or instructions for disposition of the decedent’s remains. Costs and expenses incurred in drilling or forcing a safe-deposit box shall be borne by the estate of the decedent. (3) Surrender to the public administrator any property of the decedent that, in the sole discretion of the public administrator, is deemed to be subject to loss, injury, waste, or misappropriation.
