Police received quite a shock when they responded to the call about gunfire coming from a flat on Kosmosgatan in the Bergsjön district of Gothenburg.
When the entered the woman’s home, they not only found a weapon, but also human bones.
The woman is now being held on suspicion of murder, with an alternative charge of manslaughter.
“We can’t rule out that she hasn’t killed someone,” police spokesperson Thomas Fuxborg told told the local Göteborgs-Posten (GP) newspaper.
Speaking with the TT news agency, Fuxborg explained there were “lots of bones” but emphasized police still don’t know how they ended up in the apartment.
“They can also have been taken from graves, a hospital, or something like that,” he said.
When police found the bones in the woman’s apartment on Wednesday night, forensic investigators were called in to confirm they were in fact human bones.
So far, police have not received any explanation as to why the woman had bones in her apartment.
“The woman isn’t someone we’ve had any previous contact with,” Fuxborg told TT.
“She was alone in the apartment.”
There is also no evidence that someone who lives in the apartment might be missing.
