The DNA from the blood on the shirt they found in the suspect's apartment matched Himchan's. Juhyun also managed to discover that the cardboard found covering the second body was a folded old refrigerator box used to transport the body based on the blood smears and drops she found on the inside of it. She also mentioned that although similar, the hand truck tire marks were different from those found near Himchan's body.
The drag marks also looked different. She said that it looked as if the killer was struggling more this time as indicated by the disturbances in the track. The bottom side of the cardboard box showed signs of dragging too so they came to the conclusion that the killer had put the body in the box, carried it to the scene using the hand truck, dragged the box from the cart for a bit before taking the body out and dragging it again to dump it.
"Why do I get the impression that these two murders are committed by two different people?" Yoona had said, frowning at the evidence.
"I feel you," Sooyoung agreed. "It's like the second one was made to look like the first one but that's impossible, right?"
"Nothing's impossible. You should know that by now," said Taeyeon.
"But no one knows the details to Himchan's murder. The Commissioner managed to keep it under wraps, remember? We haven't even solved it," argued the tall inspector.
"Yes but we have that accomplice theory. Maybe he decided to take matters into his own hand. He looked smaller in the video so he would probably struggle to duplicate what his partner did to Himchan."
"Maybe." Yoona then yawned. "I think we need some sleep. All of us. Where's Haejoon oppa?"
"I think he's still asleep. Probably more tired than he thought," said Taeyeon.
"I'll check." Sooyoung then left the room before anyone could say anything.
Yoona and Taeyeon exchanged quick glances before the captain straightened up. "Let's hope they work things out soon. Let's go home, Unnie."

Sooyoung opened the break room door without making a sound and saw Haejoon sitting on the couch, holding a cup of coffee in his hand.
He looked up and their eyes met.
Neither moved or said anything for the next few seconds and Sooyoung decided to break eye contact, turning to leave.
There was a sigh and it stopped her in her tracks.
"I was just checking up on you," she said without turning her head. "Everyone thought that you were still asleep."
"Well, I'm not."
"Go home then, Oppa. Rest at your place. Not here."
"Why should I?"
"Huh?" Sooyoung finally turned to look, once again meeting Haejoon's tired eyes.
"Why should I go home and rest?"
"Because you're tired."
Haejoon kept his eyes on Sooyoung, waiting for more.
"A tired you won't help us solve this case," said the tall young woman.
"So it's about the case?"
"Yes. What else is there?"
Another sigh came from the man as he took a sip from his coffee.
"You were the one who shut me out, Oppa. Don't act as if I didn't care about you because I did." Sooyoung then lowered her voice. "I still do."
She was closing the door when she heard him mumble.
