Please have a more specific question. What happens to who?

Death of the Sponsor
If the sponsor dies after the principal applicant has immigrated to the United States but before all qualified family members who are traveling later (following to join) have immigrated, can they obtain another sponsor?
Yes. A substitute sponsor may serve as the sponsor in such circumstances. The substitute sponsor must be an American citizen or lawful permanent resident, at least eighteen years of age, domiciled (living) in the United States and having sufficient income.
The substitute sponsor must be related to the applicant in one of the following ways: spouse, parent, mother-in-law, father-in-law, sibling, child, son, daughter, son-in-law, daughter-in-law, sister-in-law, brother-in-law, grandparent or grandchild.
The death of the sponsor ends any obligation to the sponsored immigrant(s), but the sponsor's estate remains liable for any requests for repayment of benefits that arose before the sponsor's death.
