merican teenager Heather Lois Mack, who is on trial for allegedly killing her mother, is taking care of her newborn baby in Kerobokan prison, Denpasar, Bali.

The 19-year-old Mack, who stands accused along with her boyfriend, 21-year-old Tommy Schaefer, of killing Sheila Ann von Weise-Mack, 62, spent her first night with the baby in prison on Monday night as she left Sanglah Hospital, having given birth there last week.

Mack gave birth to a healthy baby girl at the Wings Amerta international standard facility of the hospital in Bali on Tuesday last week, via caesarian section. The total cost of care at the hospital reportedly reached Rp 57 million (US$4,000).

After spending seven days in hospital, guarded by two police officers, Mack and the baby girl were taken to prison on Monday afternoon by two prosecutors.

'€œAs the doctor said Heather and the baby were healthy, we picked her up and brought her back to Kerobokan prison,'€ prosecutor Eddy Artha Wijaya said.

When leaving the hospital, Mack covered the baby, named Stella, with a scarf while cuddling her. She refused to speak to the media.

A source said she was excited to meet her boyfriend Schaefer, the father of her baby.

Mack has been placed with the baby in a cell with seven other female prisoners. One cell mate is Julaikah Noor Aini, or Noor Ellis, who is suspected of murdering her Australian husband Bob Ellis.

Kerobokan prison warden Sudjonggo said Mack would be given access to the same facilities as the other prisoners.

'€œThere will be no special treatment, but we will remind her cell mates to be careful, as there is a baby in the cell,'€ Sudjonggo said.

However, he ensured that the baby would receive the care it required.

'€œWe will provide the facilities, including access to health services,'€ he said.

There is also a seven month baby being cared for inside the prison, from another female prisoner who has been convicted of murdering her stepson.

Mack and Schaefer were charged with premeditated murder in August last year.

Both are charged with several articles of the Criminal Code, including Article 340 on premeditated murder, which carries the death penalty; Article 338 on murder, carrying a 15-year prison term; Article 170 subsection 2 on violence causing death, which has a maximum 12-year prison term; and Article 221 on hiding a criminal, carrying a nine-month prison term.

The victim'€™s body was found in a suitcase that was allegedly placed in a taxi trunk by the young couple at the St. Regis Bali Resort in Nusa Dua on Aug. 12, where the three had been vacationing.

Mack and Schaefer left the hotel via the beach and were arrested on Aug. 13, a day after the murder, at the Risata Bali Resort in Kuta, where they had stayed the night.

Two weeks ago, Schaefer confessed he had killed Mack'€™s mother. He told the court he was angry after the victim had threatened to kill his unborn baby and had strangled him for about half a minute.

Schaefer told the court that Mack'€™s mother had not supported their relationship.

He said von Wiese-Mack was angry when she found out that Mack was pregnant.

The victim, he said, had insulted him using a racial slur and had called her daughter a prostitute. Schaefer said he could not remember how many times he had struck the victim.
