Nan Zhan said, "What we need is not his testimony but the evidence in his possession."
Nan Zhan called Nan Yu again, but it was still impossible to get through.
He also reached out to the police station and a few people who were familiar with Nan Yu, asking them to inform him immediately if they heard any news about Nan Yu.
Nan Yu often went out on assignments, and it was common for him not to be found due to poor signal or because the task required no contact with the outside world.
However, not being able to find him complicated the case.
Nan Zhan took a drag of his cigarette, blew a smoke ring, and under Jian Si's anxious questioning, he said, "Remember the night Nan Yu took a group photo of the four of us?"
With this reminder, Jian Si immediately recalled. Indeed, Nan Yu had taken such a photo. At that time, she and Zhengzheng were sitting at the table, with Nan Yu and Nan Zhan standing behind them, Nan Yu using his own phone to take the selfie.
