WA roundup: Murder charge, fatal crashes, mouse plague warning and dramatic rescues on April 4
A series of urgent and unsettling developments unfolded across Western Australia on Saturday, 4 April 2026, with a murder charge laid after a young woman was found unresponsive in a home, three people killed in separate road crashes within hours, and an urgent warning issued over a fresh mouse plague.
Emergency crews also carried out a dramatic maritime rescue and a separate flood emergency that stretched through the night, while a service station came under scrutiny for its fuel sales. In the most serious case, attempts were made to revive a young woman discovered unresponsive in a home, but she was declared dead soon after being found.
A murder charge has been laid in connection with her death. On the roads, two teenagers and one man died in separate crashes that occurred just hours apart on one state’s roads, underscoring a deadly run of incidents in a short span of time. Authorities issued an urgent warning over a fresh mouse plague, with the alarm punctuated by the refrain, “They’re everywhere,” as communities were urged to stay alert to rapidly rising numbers.
Rescuers mounted a dramatic operation after a woman was found clinging to a channel marker, pulling her to safety from the water. In a separate ordeal, a man endured 12 harrowing hours clinging to a tree in raging floodwaters before being saved. Meanwhile, a service station is being investigated over allegations it sold low‑grade fuel as premium, prompting consumer concerns and regulatory scrutiny.
The incidents cut across crime, road safety, public health and emergency response, marking a turbulent day of developments across the state.
