Ecclestone, who has autism and difficulties in social settings, was playing PlayStation in his room when Pitcaithly knocked on his door and confronted him about making a mess in the communal kitchen and for getting a knife stuck in the sink.
He denied the accusations and the pair became embroiled in a loud and heated argument.
Insults were traded until Pitcaithly picked up a plate from the floor and threw it at Ecclestone.
Ecclestone picked up a wooden-handled knife with a serrated blade from the floor of his room and threatened to cut Pitcaithly’s neck open.
Pitcaithly replied with words to the effect of “go ahead and do it”.
Williams, who was there visiting a friend, heard the commotion and ran upstairs to intervene.
Despite standing in between the pair and trying to defuse the situation, Ecclestone swung his knife over Williams and stabbed Pitcaithly on the top of his right shoulder.
Williams remained standing where he was as Ecclestone swung the knife again.
This time he struck Williams in the neck.
Williams grabbed his neck which was “bleeding profusely”, according to the summary, and walked downstairs to ask for help.
He repeatedly said he had been stabbed and to call an ambulance before collapsing on the floor in the kitchen.
Other residents rushed to his aid and tried to staunch the heavy bleeding, as emergency services were called.
Williams died of his 7cm deep stab wound in Waikato Hospital two days later.
Meanwhile, Eccleston locked himself in his room and waited for police.
He told them he had acted in self-defence, and acknowledged stabbing both men.
In court, Justice Michael Robinson convicted Ecclestone of the charges and remanded him back into custody ahead of sentencing next month.
