The man was found dead on a field in Fjärås south of Kungsbacka and was suspected of having been murdered during a period.
Now the murder investigation is being dropped after the death. The final autopsy report shows that no crime was behind the man's death, according to a press release from the police.
The deceased man, who was a Norwegian citizen, was found in mid-December. A man was arrested two days later suspected of murder, but was released on bail again after just over a week.
