Emotional accounts from relatives of the victims and survivors of the partial collapse of a boat dock gangway on Georgia’s Sapelo Island and a newly released video of the frantic rescue efforts paint a dramatic picture of Saturday’s incident.

White’s family was among hundreds visiting the isolated Georgia barrier island Saturday for a fall festival spotlighting the history and culture of its tiny Gullah-Geechee community of Black slave descendants. The celebration gave way to tragedy when the gangway collapsed, sending seven visitors to their deaths.
