I also wondered how this person funded buying things from Amazon, when it hasn’t been reported that he ever had a job. Perhaps his parents allowed him access to their credit cards? Perhaps he was claiming benefits? Whatever, he had access to money, and he wasn’t using it to buy food, but instead to buy machetes and knives, arrows, and other implements, and the ingredients to make deadly poison. If he didn’t buy the knives and machetes, who did? We know he bought things from Amazon regularly because the neighbours apparently complained that he had them delivered to their houses rather than his own, and one neighbour apparently complained to his father about this and asked him to get it stopped.
I wonder what the parents thought about him collecting knives and machetes? What did they know and do about it? I know they called the police sometimes but that was to deal with specific incidents. What did they do about the collection of knives and other weapons?
