My guess is an “illegal search”....But it certainly appears that this young man’s behavior was getting out of control one step at a time with very few consiquences.
Often being suspended from school is considered a reward rather than a punishment by the child. Only the parents see it differently. Since dad took him from his mother’s home and he was spending the suspension at dad’s girl friend’s house, it may have been an even bigger reward for Trey.
The kid does something, and gets away with it - they do something bigger. They do something bigger, and gets away with it - they do something even bigger.
The pattern repeats and continues until somebody is laying in a pool of their own blood - either a victim, or the ‘child.’ Everybody that lets them get away with it IS an accomplice.
