In "Mrs. Cop" Kim Hee Ae wanted to find evidence and investigated Son Byung Ho. Nonetheless, she was not successful.

On the 8th episode of SBS Monday/Tuesday drama "Mrs. Cop" (script Hwang Joo Ha, director Yoo In Shik) broadcast on August 26th, the first team of detectives investigated the serial murders of the missing girls.

In the street coerners of the market, they found a body of the teenage girl. Choi Young Jin (played by Kim Hee Ae) saw through the vide of the CCTV that at the time that the culprit was leaving, the president of KL group Kang Tae Yoo (played by Son Byung Ho) had passed by that area as well.

Choi Young Jin went with the members of the first team of detectives to ask whether they had seen a man. CEO Kang said, "I've never been there and therefore have never seen them." At this, Choi Young Jin asked to search in the car but while Choi Young Jin was looking into the driver of the car, he had left stealthily.

Learning of this, Choi Young Jin and the team members requested to inspect the car after blocking CEO Kang. He said that he would cooperate even though he felt bad. Nonetheless, the memory card was already with CEO Kang and the detective team one couldn't find anything.
