Whenever any member is killed, or dies, as a result of any injury received during the performance of his duty, or from sickness caused by the discharge of such duty, or after retirement for service connected disability, an annual pension shall be paid in equal monthly installments to his widow, or child, or children, in an amount equal to one-half of his terminal salary, not to exceed two hundred fifty dollars ($250) a month. The pension shall be paid to the widow, during her lifetime or until she remarries. Thereafter, or if there is no widow qualified to receive the pension, it shall be paid to such of his children, through their guardian, as are under eighteen years of
age, to be equally divided among them in the following amounts:
For one child
$50
For two children
$75
For three or more children
$100
A widow of a pensioner is not entitled to a pension unless she was married to the deceased pensioner at least five years prior to the date of his retirement. If the widow, widower, child, or children marry, the pension paid to the person so marrying shall cease. If a member is subject to the provisions of Section 32341 and does not exercise the option provided for therein, the amount shall not exceed one hundred fifty dollars ($150) per month.
