Section 9. The department shall provide for the decent burial of all deceased persons who are at the time of death recipients of aid or assistance under this chapter, all deceased persons who, although without means of support at the time of death, did not apply for such aid or assistance; and all unknown persons found dead. It shall also provide for the grave of each such deceased person a suitable marker bearing the name and dates of birth and death of such deceased person, if known, and for the opening of such grave. The expense thereof may be recovered of their kindred, if any, chargeable by law for their support in the manner provided in this chapter; and if the expense of their funeral and burial is not paid by such kindred, an amount not exceeding eleven hundred dollars; provided, however, that the total expense of the funeral and burial does not exceed fifteen hundred dollars; and provided, further, that any payment made by the department shall be reduced by whatever resources may exist in the estate of said person.
