Zhao Tianxing spoke haltingly. "That's right. If Wang Liang had adamantly refused to confess, there really would have been nothing we could do."
In other words, Hu Bin not only cleaned up Zhang Zhanhui's mess, but he cleaned up Wang Liang's mess as well.
Otherwise, with Wang Liang's clumsy attempt to stage a break-in and robbery, he would've been caught the morning after the crime.
Shen Xin nodded in agreement. "I remember a detail. The mark outside Li Siyu's door must have been made by them on the spot."
"And when they did it, not only did they randomly carve similar marks on multiple floors, but they even carefully caught the falling plaster dust."
When he first discovered the mark, Shen Xin had specifically checked the floor for dust.
If it had been carved that night, the plaster dust would have definitely been on the floor.
