The incident occurred in June this year in Klintehamn. The man pushed another man into the water and then left the scene without ensuring that he could get out.
The victim was found in the water and later died in hospital.
The man was initially charged with murder, but the district court (the local court) found that it had not been proven that he intended to kill. He will instead be convicted of manslaughter.
In addition to a suspended sentence, he must pay 145,000 kronor (about $13,800) in damages to the victim's relatives.
