Yunzhou, Special Investigation Group office, evening.
"Sister Miao," Zeng ke reported to Miao Ying,"I checked the case records in the archive, but I didn't find any similar cases!"
"Oh?" Miao Ying pinched her chin and asked,"you searched all the major cities?"
Zeng ke explained,"it was an electronic screening. Not only in the major cities, but all the pending cases in the entire country in the 1990s were investigated!"
"Pending cases," cui Lizhu reminded him,"could it be that the case has already been closed, such as catching the wrong murderer?"
"Well, it's not easy to investigate a solved case!" Zeng ke said,"at that time, there was no online database. Cases that had been closed without any objections were generally not entered into the electronic database. We could only go to the local police stations to investigate ..."
"Oh, okay then ..." Miao Ying said."Maybe the left-ear murderer never came to our country?"
