The victim was a woman living in the same apartment building as the convicted. She had apparently confronted him about his dogs.
The accused said in court that the victim had torn his coat, sending him into a "white rage."
The man began assaulting the woman in the stairwell of the apartment building and then carried her to an old port on the shore.
He continued to beat her, eventually dragging her into the sea.
