On Monday morning, Örebro district court decided on her release date having taken into account her 28 years served in prison in the States, and her six months jailtime in Sweden.
Under Swedish law, she can be released after serving two thirds of her sentence, which means she'll be free sometime in the Spring of 2011.
The court found that there was no concrete grounds for believing that Östberg posed a risk to Swedish society and that her remaining prison time could be used to adjust to that society. The National Board of Forensic Medicine had told the court that Östberg would commit new crimes if her return to freedom wasn't gradual.
Östberg left Sweden for the States with her mother when she was a young girl. She was sentenced to between 25 years and life in prison for her part in two murders, including that of a policeman.
Since her return to Sweden, Östberg had had a number of probations, and hasn't been recognised while out in society.
Östberg's lawyer Johan Ödlund told TT that his clinet can now start planning for the future.
" She is very pleased, relieved. She feels happy that she can now plan her future. She wants to rejoin society and work with animals."
