South Australian police have classified the deaths of 36-year-old Helena Wright and her 23-month-old daughter as a murder-suicide following their discovery in waters off the state's southeastern coast on Monday [1]. Wright's three-month-old son remains missing, prompting an ongoing search operation in the area near Port MacDonnell [1].
Wright's vehicle was located near Port MacDonnell with its engine still running, leading authorities to the water where the bodies were found [1]. According to Superintendent Trent Cox, the prospects of locating the infant alive have become remote, with the officer stating that "three days on, the chance of finding the baby alive is zero" [1]. Adverse water conditions have prevented the deployment of underwater drones to aid in the search efforts [1]. South Australian Emergency Services is mobilizing from Adelaide to assist in the operation [1].
