UPDATE: A mother accused of murdering her teenage son will remain behind bars and face court in mid-January.

Kim Margaret Earle, 46, briefly appeared in the Southport Magistrates Court this morning as her case was set for a mention on February 19, 2014.

The unwell woman shuffled into the prisoners' dock in a white hospital-style gown with her face downcast and cried quietly after speaking with her lawyer.

Legal Aid duty lawyer James McNab asked permission for her to remain seated due to her ill health.

"She is quite unwell," he said.

"Since her arrest she has had a number of visits from various health professionals and that will continue."

Earle is accused of killing her 18-year-old son and reporting his death to triple-zero on Friday morning.

Police and paramedics found his body in the family home in Little Norman St about 8am on Friday.

Hours later police found a distressed Earle at Narrow Neck beach and she was taken to hospital.

On Saturday police interviewed the her at her hospital bed and charged her with murder.

Today in court police did not reveal the name of the deceased man or the circumstances surrounding his death.

Earle was unable to seek bail today as bail applications for defendants accused of murder can only be heard in the Supreme Court.

She will appear in court via video link from a women's jail on her next court date.

A TEEN'S DEATH AND A MOTHER'S SORROW

On Saturday police interviewed the 46-year-old woman in her hospital bed and charged her with murder.

She has since been taken to the Southport Watchhouse and is expected to appear in the Southport Magistrates Court this morning.

Detectives spent the weekend scouring the quaint cottage in Little Norman St for evidence and closed the small side street during their investigations until midday yesterday, when the street was reopened as investigators sent their mobile police van away and removed police tape from the home's wooden picket fence.

Neighbours said the mother and son had kept to themselves but the teen was believed to suffer a medical disorder and had been known to become aggressive.
