She will be deported back to the United States.

Mack was initially sentenced to 10 years in prison, but became eligible for release this year due to good behavior, according to Favia.

Mack and her then-boyfriend, Tommy Schaefer, were found guilty of bludgeoning Mack's mother — 62-year-old Chicago socialite Sheila von Wiese-Mack — to death at an upscale hotel in Bali, Indonesia.

At the couple's trial, Schaefer confessed to the killing and admitted to hitting von Wiese-Mack repeatedly with a metal fruit bowl.

He claimed that when von Wiese-Mack found out Mack was pregnant, she became very angry and threatened to kill the couple's unborn baby — and tried to strangle him for nearly 30 seconds.

After the slaying, the couple stuffed von Wiese-Mack's body in a suitcase and, hours later, placed the suitcase in the trunk of a taxi before fleeing the hotel.

The driver notified police after he spotted blood leaking from the luggage.

The Chicago couple faced possible execution by firing squad, but Mack was sentenced to 10 years in prison and Schaefer was sentenced to 18 years.

Mack spoke to PEOPLE from prison in 2015, saying about her mother: "She never wanted to be separated from me, and yet she also hated everything about me. It was complicated."

Mack's daughter, Stella, was allowed to live with Mack in prison until she turned 2. That is when Mack turned the child over to an Australian-Balinese woman named Oshar Putu Melody Suartama, who befriended Mack shortly after she was arrested.

The woman agreed to care for Stella until Mack's release.
