Is it possible to directly arrest Song Junwu and reopen the investigation from back then?
It's certainly feasible. The cases of Zhang Chi being murdered, Wang Yajuan being murdered are different from the disappearance of two people back then. As the legal representative of Green Rattan Jewelry, Song Junwu is definitely connected to this.
If Song Junwu is arrested now and something can be extracted from him during interrogation, then the case can be easily resolved. It's even possible to solve the case of the eight skeletons discovered beneath the bridge.
But there's another concern. What if nothing substantial is gained from interrogating Song Junwu upon arrest?
What do we do then?
Song Junwu, as the general manager of Songbei Mining Transport Company, must be a core figure at Songbei Mining. If there's an issue with Songbei Mining, and we arrest Song Junwu, it'll surely alert them.
Arresting Song Junwu without solid evidence is too risky.
