The woman must then be deported.
Örebro District Court considers that the woman has behaved in prison and that there is no risk of a relapse into serious crime.
The sentence is set at 27 years and six months.
The murder, which had financial motives, occurred in early 2005. The victim was found in a bathtub several months after the murder.
In addition to the woman, two men were also sentenced for the crime.
