South Australian police investigate the deaths of a 36-year-old mother and her 23-month-old daughter after both are found in the ocean near Port Macdonnell. Multiple outlets report that officers retrieve the bodies after a search began on Monday. Police say the deaths are being treated as a possible murder-suicide. Investigators also continue efforts to locate the mother’s third child, a three-month-old boy who was reported missing. While the search continues, coverage indicates that chances of finding the baby alive are fading. Police describe the ongoing search as a retrieval effort, focusing on locating the infant rather than assuming he is still alive. The reports do not detail any additional suspects, motives, or evidence released publicly at the time of writing. Authorities have not provided further information in the excerpts beyond the investigation’s scope, the identity and ages of the deceased, and the continued search for the missing baby.
