Can a stepparent obtain a Gold Star Family plate if their stepchild was a member of the military?

Currently, Tenn. Code Ann 55-4-264 does not state “stepparent” or “stepchild” as an eligible person. The law states “to each eligible person in the state whose spouse, parent, sibling, or child served and died in the line of duty in the Armed Forces of the United States or its allies, or died as a result of injuries sustained in such service.”
