The 31-year-old arrived at Arlanda airport at 9pm on Tuesday and was sent directly to a detention centre in Västerås in central Sweden, Aftonbladet reports.
The suspect left Arboga on March 18th, the day after the murders of two children, 1 and 3, and the attempted murder of their 23-year-old mother .
Ever since she was arrested by German police, the justice system in Sweden has worked to have her surrendered to the country, a move that was opposed by the woman’s lawyer.
The 31-year-old suspect was previously romantically involved with the 23-year-old’s current boyfriend.
The murdered children’s mother left hospital for the first time since the attack just a few days ago.
In an interview with Aftonbladet, she says that it has taken until now to fully understand that her children are gone but she does not remember anything from the night of the murders.
