Heather Mack is facing a tougher jail sentence after confessing to killing her mother herself in a prison video uploaded to YouTube.
Balinese prosecutors said they were reviewing the videos during which Mack said coldly 'I killed her myself' and 'I don't regret killing my mother'.
The 21-year-old is currently serving a 10 year sentence after being convicted alongside boyfriend Tommy Schaefer in 2015 of murdering Sheila von Wiese-Mack and stuffing her body in to a suitcase at the St Regis Hotel in Nusa Dua.
'If Mack is indeed the mastermind of the murder, the video can be used as evidence in the case, and the sentence should be heavier than it is now,' Ashari Kurniawan, a public relations official in the Bali prosecutor's office, told Reuters.

Bali suitcase killer Heather Mack is facing a tougher sentence after confessing to murdering her mother alone in a YouTube video she shared last week (above)
Mack's attorney said she had been 'pressured' into making the video and that Schaefer, who is serving 18 years for the killing, wanted to 'attack' her.
His lawyers have not responded to Mack's YouTube videos.
They were shared online on Thursday and detail how she plotted to kill her mother after learning that she was responsible for her father's 2006 death.
James Mack, a Chicago composer, died in Athens, Greece, from a pulmonary embolism during a holiday with his wife and daughter.
Mack believes he was murdered by her socialite mother and that the Bali killing was her revenge.
'I don't regret killing my mother and as evil as that may sound, that's my reality.
'When I was 10, my mother killed my father in a hotel in Athens, Greece.

Mack said she murdered her mother, Sheila von Wiese-Mack (left) herself and that her boyfriend Tommy Schaefer (right) only helped her dispose of the body by stuffing it in a suitcase
'Two weeks before I came to Bali, I found out that she killed my father and I made it up in my heart, in my mind, my soul, in my blood, in the oxygen running through my body, that I wanted to kill my mother,' she said.
She made the videos out of remorse for dragging Schaefer into the murder plot, she said.

'I got this whole new savage idea in my head that I wanted to kill her in a hotel room because she had killed my father in a hotel room.'
Mack claimed she forced Schaefer into joining her and her mother on the trip, booking him a ticket with her mother's credit card.
Once they'd arrived in Indonesia, she said she told him of her plan and forced him to help her dispose of her mother's body.
When the pair were arrested, Mack said she and her lawyers convinced him to take the fall for the killing so that she could keep her inheritance.
'My lawyers and I, because of the fact that if I get money, if my article that I was charged with was not that I'm the one that killed her, I'm still entitled to the money and therefore I can pay the lawyers more.
'So we told Tommy together, my lawyers and I, that if he didn't take the blame in the court, that he would get the death penalty.'
They said Schaefer bludgeoned von Wiese-Mack to death after she launched racial slurs at him.
In the videos, Mack said he had chosen to speak out because she was 'tired of living in a lie'.

Through tears, she told Schaefer that she was sorry and that she loved him before signing off.
'I'm sorry you won't be able to get a job, I'm sorry everybody thinks that you're some crazy killer. This is the truth and whoever is watching this, don't hate Tommy.
'He's innocent. I'm not. I love you Tommy.'
Mack gave birth to the couple's daughter Stella while in police custody for the murder. She now lives with the baby in Bali's notorious Kerobokan Prison where Schaefer claims she drinks, smokes and has sex with female inmates.
Mack enjoys preferential treatment at the prison and has a cell phone which she uses to upload selfies on Instagram.
She presumably used the phone to film her confessional videos to share on YouTube last week.
