Half a month after Timmy's accident, the police finally found a new breakthrough.
The food supply for the Summer Camp was shared with a highly secured campsite at the time.
The food supply for this highly secured campsite had always been strict and provided by a fixed supplier.
The supplier had claimed that the variety of the food provided to the Summer Camp and the campsite were the same.
Moreover, the list of food categories for the next month had been determined at the end of the previous month.
At the end of last month, Timmy and the others were even at school for interviews.
So, the possibility of the supplier having a problem was ruled out at that time.
However, yesterday, the supplier suddenly contacted the police.
They found that the food list had been tampered with on the third day after the start of the Summer Camp.
