Search continues for missing two-month-old after mother, sister found dead off South Australia coast

Off the southeastern coast of South Australia, near Cape Northumberland, the ocean has taken a mother and her toddler daughter, and may yet hold a two-month-old boy whose fate remains unknown. What began as a report of an idling, unattended car in a coastal car park became, within hours, one of the region's most sorrowful searches. Authorities press on through rough seas and poor visibility, holding open every theory about what brought this family to the water's edge, while a community waits in the particular anguish of not yet knowing.
