Meanwhile, Zhang Hui's group had also come across a significant clue.
The owner of the small shop had always been running his business in the store, which could be corroborated by nearby merchants, so Song Jinfu's disappearance was indeed unrelated to him.
According to the shop owner's description, the sketch artist from the Criminal Investigation side had also managed to produce a preliminary sketch.
While working on the sketch, Zhang Hui's team also found some important clues by reviewing surveillance footage around the shop.
The person was wearing a blue down jacket and a baseball cap, with very distinctive features.
Although there was no video surveillance inside the small shop, several other stores or restaurants in Spring Breeze Lane had plenty of surveillance cameras.
After an afternoon of investigation, Zhang Hui finally found a frontal shot of the suspect from a hotel's surveillance camera.
