German police made the seizure of the items when the 31-year-old gave herself up over two months ago, according to Vestmanlands Läns Tidning (VLT).

The items came into the possession of Västerås police on Wednesday. They are now being analyzed by police IT technicians to try to extract information helpful to the case.

The woman has claimed in interviews with police that it was her interest in archaeology that led to her being in Arboga at the time of the murders on March 17th, according to reports in the newspaper Aftonbladet.

The woman’s mobile phone is therefore of particular interest to police as the woman has claimed that she used it to photograph rune stones in the town. She claims that the photographs were then deleted because they were of poor quality.

If the German woman’s story is true then the photographs should be recoverable.

“Generally speaking, it should be possible to recover certain things,” said Jan Sjöberg of Västerås police to VLT.se.

The laptop is the computer that the woman has used to update her Facebook page and surf the internet.

The items of clothing are those that the woman was wearing when she handed herself in to police in Germany and have been sent to the Swedish National Laboratory of Forensic Science (SKL) for analysis.

The 31-year-old German woman is being held on suspicion of the murder of two children and the attempted murder of their mother in Arboga on March 17th 2008.
