Although they didn't know exactly who was responsible, they had a suspect in mind, Zhao Qinghe from the Zhao family.
After all, Zhao Qinghe had been inquiring about Xu Jinzhi a few months ago, and considering those Xu Jinzhi had offended, only Zhao Qinghe truly had a motive for the crime.
So, during the investigation, they focused their examination on Zhao Qinghe.
But so far, they hadn't found any clue linking this incident to Zhao Qinghe.
They only found a security guard, but the guard had disappeared, having vanished the night before Xu Jinzhi's mishap, right after finishing his night shift.
It was a complete disappearance, as if this person had never existed in the city.
Such obvious actions made it clear someone was helping from behind the scenes, yet frustratingly, they couldn't determine who it was.
As for Zhao Qinghe, he had already returned to S City a few days earlier for work, which was a routine trip, and he was expected back in A City in a couple of days.
