Mother charged with murder of her toddler, who allegedly died of neglect

A mother charged with the murder of her eight-month-old son is accused of neglecting him in the days before paramedics found him dead in the family home west of Brisbane.

Police will allege neglect was the twin baby's cause of death and have appealed for the partner of the accused woman, who lived in the house at the time, to come forward and speak to detectives.

The baby was found dead on June 21, 2019 at a home in Sonter Street, Raceview. The victim's twin brother and older sister, who was aged four at the time, have been cared for by someone else since the death.

The 34-year-old woman was charged with murder, interfering with a corpse and failing to provide the necessities of life for the three children. She will appear in an Ipswich court on Thursday.

Detective Inspector David Briese appealed on Wednesday for the 41-year-old man, who lived at the address at the time, to contact police as they believe he could assist investigators further.

"There was no breakthrough as such, this has more been the result of meticulous management and investigation since June 21 last year," Inspector Briese said.

"In such matters where it involves children, we, like everyone, would like to have it solved quickly, but we have to be meticulous."

More to come.
