Siv Eriksson’s Computer Data Erased and Backups Stolen

The erasure of Siv Eriksson’s computer data and theft of her backups turned a seemingly private loss into a major investigative clue. Someone entered her flat while she was away, stripped her of years of work without taking the valuable equipment, and left Kurt Wallander to consider whether the real target was information connected to the dead Tynnes Falk.

The discovery

Eriksson had gone to visit her mother in Simrishamn and stayed the night because it had grown late. When she returned the next morning, her computer would not start. Its hard drive had been emptied; every backup disk was gone, along with a reserve hard drive. The loss was not limited to the computer’s working files: there was no copy left from which she could restore them.

The scale of the damage was personal as well as practical. Eriksson told Wallander that all her work had vanished, and she was visibly shaken as she showed him the empty computer and the cabinet where she had kept the backups. She had been away for only one night, and the intruder had acted during that absence.

Signs of access and preparation

Wallander checked the flat’s front door and windows. Neither showed signs of forced entry, and Eriksson said she had already checked them herself. The evidence pointed to someone who could enter without breaking in and who knew when the flat would be empty.

Eriksson had given Falk a spare key so he could reach the flat while she was away in case of an emergency. She said he had kept it in his flat on Apelbergsgatan and, as far as she knew, had never used it. Because Falk was dead, Wallander considered the possibility that someone had used the keys he had held. The key made access plausible, but the evidence did not establish who had entered.

Data, not equipment

The intruder left the computer equipment behind. Wallander therefore concluded that the purpose was not ordinary theft: whoever entered wanted what was stored inside, not the hardware itself. Eriksson had used a password, Cookie, her childhood nickname. She said that no one else knew it, including Falk, though she also explained that she used the nickname when signing emails to a friend in Austria. Those messages were stored on the computer, making the password a possible clue if someone had already gained access to her files.

Eriksson insisted that her work held no classified information and that she had not worked on especially advanced projects. She described herself as meticulous about sorting and cleaning her files, which made it difficult to identify anything she might have overlooked. Wallander nevertheless pressed the possibility that some item in the computer had value to someone else, or that an intruder might have been searching for material Falk had concealed there. He also considered whether Falk could have used her computer without her knowledge, since he had possessed a key, but Eriksson doubted this and Wallander had no proof that it had happened.

The case’s new direction

The empty hard drive, missing backups, and undisturbed doors and windows gave Wallander what he felt was his first clear picture of the investigation: someone had watched Eriksson and chosen the moment she was away, then entered with access that left no obvious marks. The scene suggested deliberate removal of data rather than a casual burglary, while leaving unanswered what the intruder expected to find.

Wallander arranged for a forensic team and asked Eriksson not to touch anything in the study in case investigators could find fingerprints. Before leaving, he asked whether Falk had ever mentioned the number 20; Eriksson could not recall that he had. Wallander connected the break-in to a wider effort to keep something secret, but the contents of the missing files—and the reason they mattered—remained unknown.
