The suspect was arrested shortly after the incident and has been in custody ever since.
The background to the crime must have been jealousy on the part of the now convicted man.
The man was primarily charged with murder but is now sentenced for causing another person's death as the district court judges that the intention was not to kill the man.
In addition, he is convicted of extremely serious assault.
The man claims that he was in an emergency situation.
The verdict was handed down in Varberg District Court on Thursday.
