The rain in Beijing is as cold as a child drifting north, erasing all traces of the past, and even creating some tear-like ditches.
A few forensic technicians, along with Jiang Yuan, circled the electrical box and its surroundings for a long time, but couldn't identify any suspicious traces.
One has to admit, a rainy night fits more with modern architecture and murder; when smooth concrete roads crisscross in all directions, the traces after rain become even harder to investigate.
Even Jiang Yuan, faced with the washed-like concrete ground, couldn't find any footprints. The electrical box was opened, revealing some fingerprint traces, which Jiang Yuan personally collected, but he didn't hold much hope.
If anyone else was involved in this case, at the very least they knew how not to leave fingerprints.
