I am glad to see that you are jumping to conclusions as not once does it mention that there was a dispute with the neighbor. It is completely possible that the neighbor was innocent and this man is just a very sick person. Either way there is NO excuse for this to happen. My thoughts and prayers go out to the family and friends of the victim. There is no amount of justice or retribution that can bring back their loved one, I hope you are able to find some peace through the grieving process.
