The most likely reason right now is that someone has died.

The most likely reason right now (I am already 100% certain) is that one or two people have died.
And these deaths probably occurred around June. But do you know why that happened?
To be honest, you did something worth jumping for, and then you jumped. You were caught rigging something, and either a fight broke out among yourselves leading to a murder, or someone committed suicide.
There is one thing I suspect right now. Because this person hasn't been causing trouble lately, the police have been relaxed; otherwise, they would have been causing a scene and picking fights on the streets.
It's probably because another alibi has been confirmed now.
Read the story about that braised chicken restaurant carefully. ^^ They probably made the laws too strict, and then someone died in the middle of it all.
