Implicated

The Shen Luo's cell phone signal kept moving until it stopped at the entrance of a supermarket.

Zou Sheng looked at the flashing signal and shook his head with a bitter smile. He said to Shen Yin, "Looks like Captain's trip is in vain."

No one would deliberately go to a supermarket so far from home. Shen Luo's phone must have been picked up by a passerby.

Sure enough, after a while, Captain Wu brought back the cell phone. He angrily took a sip of water, then took a deep breath. "It was picked up by a young girl. I've already questioned her carefully. She said that she was attending a tuition class nearby. After class, she saw a cell phone by the roadside and took it. She didn't see who took Shen Luo away."

Meng Heng slammed the table in frustration and said in a deep voice, "The trail is cold again."

Zou Sheng snapped his fingers, raised his eyebrows, and pointed at the screen proudly. "Not necessarily. Look what I found."
