A missing Queensland mother has been found dead in remote bushland after a desperate five-day search, with the father of her four-month-old baby now accused of her murder.

Jana Armstrong, 30, disappeared from her home in Newtown, Toowoomba, on July 7, triggering an extensive police investigation and community search after her abandoned vehicle was discovered near her home.

Human remains believed to be those of Ms Armstrong were found late on Saturday in rugged bushland at Redbank Creek, near Ravensbourne National Park and off Esk Hampton Road.

Police arrested 48-year-old Dharminder Singh early on Sunday at a property in Harristown.

Singh, Ms Armstrong’s former partner and the father of her infant son, has been charged with murder as a domestic violence offence.

He appeared before Toowoomba Magistrates Court by video link on Monday and was remanded in custody.

Singh’s lawyer told the court his client maintained his innocence and intended to defend the allegations.

The case has been adjourned until October 1, with police expected to provide a brief of evidence by September 14.

For Ms Armstrong’s family, the discovery brought a devastating end to days of uncertainty.

Her sister Faith Isaacs said her heart was “completely broken”.

“There are simply no words to describe the heartbreak and devastation I am feeling,” she wrote after the body was found.

“Losing my beautiful sister in this way is something I will never be able to understand or put into words.”

A disappearance that immediately alarmed her family

Ms Armstrong was a disability support worker and the devoted mother of a four-month-old baby boy.

She was last seen at her Newtown home on Tuesday, July 7.

Her family quickly raised the alarm because disappearing without her child was completely out of character.

Relatives described Ms Armstrong as deeply devoted to her son and said they could not believe she would voluntarily leave him.

Her sister previously described her as “very caring” and “the best sister and aunty and an even better mother to her son”.

The discovery of Ms Armstrong’s white Hyundai Kona added to the family’s fears.

The vehicle was found abandoned and unlocked near her home, reportedly left in a position that immediately attracted attention.

As the hours passed without contact, family members, local volunteers and emergency services joined the effort to find her.

Images and appeals carrying Ms Armstrong’s name and photograph spread rapidly through the Toowoomba community and across social media.

Her family pleaded for information.

Police began reconstructing her final known movements.

What started as a missing-person investigation gradually developed into a major criminal inquiry.

Body found about an hour from Toowoomba

The search ended in tragedy when human remains were located in remote terrain at Redbank Creek on Saturday night.

The area is near Ravensbourne National Park and approximately an hour’s drive from Toowoomba.

Police established a crime scene and began the difficult process of recovering and examining the remains.

Although formal forensic identification was initially pending, investigators said they believed the body was Ms Armstrong’s.

The discovery dramatically changed the direction of the investigation.

Within hours, police arrested Singh at a West Street property in Harristown.

Queensland Police classified the alleged killing as a domestic violence-related homicide and charged him with murder.

Further reporting from Monday’s court appearance confirmed Singh also faces charges relating to the arson of a motor vehicle and an alleged breach of bail.

Police allege a vehicle was set alight the day after Ms Armstrong disappeared.

The precise evidence connecting that allegation with the murder case has not yet been publicly tested in court.

Singh has not entered a formal plea to the murder charge and, through his lawyer, has indicated he will contest the allegations.

Under Australian law, he is presumed innocent unless and until proven guilty.

Singh initially spoke to police as a witness

One of the most significant details disclosed by investigators is that Singh was questioned early in the missing-person investigation.

Darling Downs Acting Detective Inspector Brian Collins said Singh initially provided police with a statement as a witness.

He was not immediately arrested.

Police continued gathering evidence as the search for Ms Armstrong expanded.

Investigators have not publicly detailed the full sequence of evidence that led them from treating Singh as a witness to charging him with murder.

That material is expected to form part of the prosecution brief now being prepared for the court.

Police have, however, revealed that there was no domestic violence order in place between Ms Armstrong and Singh.

Detective Inspector Collins said a domestic violence order existed in relation to another former partner of Singh.

The absence of a DVO between Ms Armstrong and the accused does not determine whether domestic violence occurred.

A DVO is a legal protection mechanism and its existence, or absence, is not itself proof of criminal guilt or innocence in a separate murder proceeding.

Police have nevertheless formally categorised the alleged murder as a domestic violence offence.

Questions over where Jana’s baby was during the alleged killing

Ms Armstrong’s four-month-old son has become one of the most heartbreaking elements of the case.

The child is the son of Ms Armstrong and Singh.

Police said during their initial Sunday briefing that investigators were still working to establish where the baby was during the period in which they allege Ms Armstrong was killed.

Later reporting indicated the infant was found with Singh at Ms Armstrong’s home after she was reported missing.

There is no suggestion the baby was physically harmed.

Ms Armstrong’s sister has since been caring for the child, according to reports from Monday’s court appearance.

Family members have repeatedly spoken about Ms Armstrong’s devotion to motherhood.

Her disappearance was considered so alarming precisely because those closest to her could not imagine her voluntarily leaving her baby.

Ms Isaacs has said her sister adored her son and had embraced being a mother.

The child will now grow up without Ms Armstrong.

Outside court, her family made clear they intend to preserve her memory for him.

A crucial 10.30pm to 1.30am window

Queensland Police are now appealing for public assistance as detectives attempt to complete a detailed timeline of Ms Armstrong’s final movements.

Investigators want CCTV or dashcam footage recorded between Toowoomba and Esk, including along Esk Hampton Road and the New England Highway.

The key period is between 10.30pm on July 7 and 1.30am on July 8.

That three-hour window is now central to the investigation.

Police are particularly interested in footage from roads connecting Toowoomba with the area where Ms Armstrong’s body was found.

Even recordings that do not appear to show anything obviously suspicious could be important.

A vehicle passing a camera at a particular time can help detectives establish direction of travel.

Dashcam footage can place cars on rural roads where fixed surveillance cameras are limited.

Images from service stations, businesses and private properties can help fill gaps in a timeline.

Investigators often build major cases by combining hundreds of apparently minor pieces of evidence.

A single vehicle sighting may mean little on its own. When matched with phone data, witness statements and other CCTV, it can become significant.

Police have urged anyone who travelled through the relevant areas during the nominated period to review stored footage rather than assuming they have nothing useful.

Remote bushland creates a complex crime scene

The location where Ms Armstrong’s body was found presents its own challenges for investigators.

Redbank Creek and the surrounding area contain rugged bushland and rural roads.

Unlike an urban crime scene, remote terrain can expose evidence to weather, animals and environmental disturbance.

Police must carefully document the recovery location and search the surrounding area for anything that may assist the investigation.

The position of the body, nearby objects, tyre impressions and other physical material can potentially help establish how and when a person reached a location.

Investigators have not publicly disclosed Ms Armstrong’s cause of death.

They have also not released detailed allegations about how the killing is said to have occurred.

Those facts may remain restricted as forensic work continues and the matter progresses through the courts.

The recovery of the body is only one stage of the investigation.

Forensic identification, post-mortem examination and analysis of physical evidence will all form part of the case.

Toowoomba community rallied around the search

Ms Armstrong’s disappearance generated an enormous response in Toowoomba.

Family, friends and volunteers searched for the young mother while appeals were shared widely online.

After police announced the discovery of the body, the focus of the community response shifted from hope to grief.

Flowers were left in Ms Armstrong’s memory and financial support began flowing to her family.

Her sister thanked everyone who had shared missing-person posts, searched, called and offered assistance.

“I want to sincerely thank every single person who has messaged, called, shared Jana’s posts, searched for her, offered support and held us in their thoughts,” Ms Isaacs wrote.

“The love and support shown for my sister and our family has been overwhelming, and I will never be able to thank you all enough.”

She described her sister as deeply loved.

“My beautiful Jana deserved so much more,” she said.

“She was so deeply loved and will be missed beyond words.”

The grief was visible again when family and supporters attended Toowoomba Magistrates Court for Singh’s first appearance on the murder charge.

Ms Armstrong’s death has deeply affected a community that spent days hoping she would be found alive.

Accused maintains his innocence

Singh appeared in court by video link on Monday.

His solicitor told the court the 48-year-old maintained his innocence and intended to defend the charges.

The defence has requested the prosecution’s brief of evidence.

The court was told that material is expected by September 14.

The case is due to return to court on October 1.

Singh was remanded in custody.

The murder charge will ultimately need to progress through Queensland’s higher courts if prosecutors continue with the allegation.

The Magistrates Court does not determine guilt in a murder trial.

At this early stage, the court process is concerned with preliminary procedural matters and the preparation of the prosecution case.

The allegations against Singh remain unproven.

This distinction is especially important as police continue appealing for evidence.

The fact that a person has been charged means police allege there is a basis for prosecution. It does not mean a court has accepted the prosecution’s version of events.

Domestic violence classification raises broader questions

Queensland Police have identified Ms Armstrong’s alleged murder as a domestic violence-related offence.

That classification has added her death to a continuing national crisis surrounding violence against women and intimate partners.

But the specific facts of Ms Armstrong’s relationship with Singh will need to be established through admissible evidence.

Police have confirmed there was no DVO between the pair.

That detail highlights one of the difficulties in discussing domestic violence homicide.

Not every victim has an existing protection order.

Not every dangerous relationship is known to police or support agencies before a serious incident.

At the same time, the existence of a prior order involving another person cannot be used to establish guilt in the present murder allegation.

The criminal case against Singh must stand on evidence directly relevant to Ms Armstrong’s death.

For Ms Armstrong’s family, however, the broader domestic violence debate is no longer abstract.

Her sister has spoken publicly about the need for greater action and stronger protection for women.

The family is simultaneously facing a criminal court process, the loss of a daughter and sister, and the responsibility of helping raise Ms Armstrong’s infant son.

The investigation is not over

A murder charge has been laid, but Queensland Police are still actively gathering evidence.

The public appeal for road footage shows detectives are continuing to reconstruct the crucial hours after Ms Armstrong was last seen.

Investigators want recordings from Toowoomba through to Esk and along Esk Hampton Road and the New England Highway between 10.30pm on July 7 and 1.30am on July 8.

Anyone who drove those roads during that period may possess evidence without realising it.

Police are also continuing forensic work connected with Ms Armstrong’s body and the broader investigation.

Further allegations may be detailed as the prosecution brief is completed, but much of the evidence has not yet been made public.

For that reason, the central facts remain carefully defined.

Jana Armstrong disappeared from her Toowoomba home.

Her abandoned vehicle triggered a major search.

Her body was found days later in remote bushland at Redbank Creek.

Her former partner and the father of her four-month-old son has been charged with her murder and other alleged offences.

He denies the allegations and intends to defend the case.

A court will ultimately determine criminal responsibility.

For Ms Armstrong’s family, no future court decision can change the reality confronting them now.

The young mother they desperately searched for is not coming home.

As her sister wrote after the discovery: “My beautiful Jana deserved so much more.”
