SYDNEY (AP) — Prime Minister Scott Morrison said today that Australians were “shocked, saddened and devastated” by the deaths of five people including three children after a car fire in apparent domestic violence.

Hannah Baxter, 31, and her children Aaliyah, 6, Lainah, 4, and Trey, 3, died after their car was set alight on a street in suburban Brisbane on Wednesday morning.

Baxter’s estranged husband and the children’s father, Rowan Baxter, allegedly doused his family with gas before setting the car alight. The 42-year-old, a former player with the New Zealand Warriors in Australia’s National Rugby League football competition, was found dead near the scene, reportedly after stabbing himself.

“Australians all over the country are just shocked, saddened and devastated about what has happened in a suburban street … where Hannah and her three children were so senselessly and maddeningly murdered in what has occurred in a terrible act of violence,” Morrison told reporters.
