a. Upon the receipt of proper proofs of the death in active service of a member of the retirement system on account of which no accidental death benefit is payable, there shall be paid to the surviving spouse a pension of 50% of final compensation for the use of that spouse and children of the deceased, to continue for so long as the person qualifies as a "surviving spouse" for the purposes of this act; if there is no surviving spouse or in case the spouse dies or remarries, 50% of final compensation shall be payable to one surviving child or, if there are two or more children, 50% of final compensation shall be payable to such children in equal shares. In the event of death occurring in the first year of creditable service, the benefits, payable pursuant to this subsection, shall be computed at the annual rate of compensation.
If there is no surviving spouse or child, 25% of final compensation will be payable to one surviving parent or 40% of final compensation will be payable to two surviving parents in equal shares.
