According to local media, the person was released after questioning on Monday, after the suspicions were weakened.
The woman, who was in her 60s, was found outside on a footpath on New Year’s Day.
The case is classified as a suspected murder or manslaughter for the time being. However, the suspicions that the woman was the victim of a crime have weakened, says Magnus Karlsson, head of the police’s serious crime group in Skaraborg, for P4 Skaraborg.
