He had no reason to commit suicide. 00:07:42.920 --> 00:07:44.589 He was held in solitary confinement. 00:07:44.672 --> 00:07:46.340 What could have possibly happened? 00:07:46.799 --> 00:07:50.720 I heard he didn't leave a will. Did he not leave any memos as well? 00:07:51.429 --> 00:07:54.432 Right. I was going to make a call. 00:07:54.640 --> 00:07:56.767 Who is Detective Park Gwang-ho? 00:07:56.851 --> 00:07:58.019 It's me. Why? 00:07:58.102 --> 00:08:00.855 Jung Ho-yeong left a letter addressed to you. 00:08:00.938 --> 00:08:02.690 Pardon? A letter? 00:08:02.773 --> 00:08:04.817 Why would he leave a letter to Officer Park? 00:08:04.901 --> 00:08:06.819 According to the worker who found him, 00:08:06.903 --> 00:08:08.946 he was holding it in his hands tightly. 00:08:14.327 --> 00:08:15.328 What is this? 00:08:15.411 --> 00:08:16.579 NOEL 00:08:16.662 --> 00:08:17.747 "Noel"? 00:08:17.830 --> 00:08:18.831 "Noel." 00:08:26.923 --> 00:08:28.382 Excuse me.

It's because the weather is nice. 00:09:08.714 --> 00:09:10.899 What brings you here this early? 00:09:14.136 --> 00:09:16.138 Since Jung Ho-yeong committed suicide, 00:09:16.222 --> 00:09:18.391 there's no way I can find out what he witnessed. 00:09:19.725 --> 00:09:22.436 There's a chance that he might have seen the killer's face. 00:09:22.520 --> 00:09:24.355 That's true. It's disappointing. 00:09:26.482 --> 00:09:29.443 Anyway, how did you figure out Jung Ho-yeong is a witness? 00:09:29.527 --> 00:09:31.487 Did he brag around that he was? 00:09:31.988 --> 00:09:32.989 No. 00:09:33.406 --> 00:09:35.992 Jung Ho-yeong insisted he was the killer until the end. 00:09:38.286 --> 00:09:39.412 I am not a witness. 00:09:41.747 --> 00:09:44.041 The person who figured out that he was a witness 00:09:44.166 --> 00:09:45.167 is Gwang-ho. 00:09:46.711 --> 00:09:47.628 It was Officer Park? 00:09:47.712 --> 00:09:50.715 He said that the real killer smoked a cigarette in the tunnel, 00:09:50.798 --> 00:09:53.509 but Jung Ho-yeong never had a cigarette in his entire life. 00:09:53.593 --> 00:09:56.762 That's how he figured out that Jung Ho-yeong was not the real killer. 00:09:57.972 --> 00:10:00.516 How does Officer Park know that the real killer 00:10:01.100 --> 00:10:02.935 smoked a cigarette in the tunnel? 00:10:03.269 --> 00:10:04.645 It happened 30 years ago. 00:10:07.898 --> 00:10:08.899 That's… 00:10:09.900 --> 00:10:12.695 Only that detective and I know that. 00:10:13.112 --> 00:10:17.116 Hide well and deep.

Do you have something to say? 00:11:07.291 --> 00:11:09.126 No, I don't. 00:11:11.253 --> 00:11:13.798 -I'll get going, Prof.. -All right. 00:11:21.305 --> 00:11:24.642 Did you tell Prof. Mok that I came from the past? 00:11:25.309 --> 00:11:26.227 What? 00:11:26.310 --> 00:11:29.021 He's the one who did the autopsy for the dead Park Gwang-ho. 00:11:29.105 --> 00:11:30.272 What did you tell him? 00:11:30.356 --> 00:11:32.566 I told him that I will tell him everything later. 00:11:32.650 --> 00:11:33.651 Did he believe you? 00:11:34.819 --> 00:11:36.529 You don't have to worry about him. 00:11:36.612 --> 00:11:38.739 Let's go. We might be late for the meeting. 00:11:45.121 --> 00:11:47.289 I thought he died that time. 00:12:09.979 --> 00:12:12.314 HYUNDAE PHOTO STUDIO 00:12:17.236 --> 00:12:20.047 LARGE REPLACEMENT OF PERSONNEL AT HWAYANG POLICE STATION 00:12:24.493 --> 00:12:25.494 What on earth... 00:12:26.829 --> 00:12:30.833 Is that why Lt. Kim didn't tell me who Officer Park was? 00:12:40.718 --> 00:12:42.386 It's nice to meet you again. 00:12:44.054 --> 00:12:45.639 Has it been 30 years? 00:12:48.058 --> 00:12:49.477 HWAYANG UNIVERSITY 00:12:49.560 --> 00:12:52.229 Jung Ho-yeong was the witness? 00:12:52.563 --> 00:12:55.816 Yes, that's the point I missed. 00:12:56.692 --> 00:12:58.736 That's why the victims were in the same group. 00:12:58.819 --> 00:13:00.988 That explains why his tools were the same. 00:13:01.706 --> 00:13:03.032 The reason Jung Ho-yeong 00:13:03.115 --> 00:13:06.535 was obsessed with skirts and used stockings as his tool 00:13:06.619 --> 00:13:10.122 was because they were the traits of the murder he witnessed. 00:13:10.581 --> 00:13:14.126 Jung Ho-yeong's suppressed, violent disposition as an 18-year-old 00:13:14.835 --> 00:13:16.920 was probably aroused at that time. 00:13:16.996 --> 00:13:20.057 I bet that murder was a crucial moment for Jung Ho-yeong. 00:13:20.140 --> 00:13:23.268 Witnessing a murder lit the fuse? 00:13:23.803 --> 00:13:27.139 He was a kind of copycat. 00:13:27.681 --> 00:13:30.359 Your conjecture that there may be 00:13:30.851 --> 00:13:33.771 another killer was correct. 00:13:34.104 --> 00:13:35.981 -But something is off. -What is it? 00:13:36.065 --> 00:13:40.027 He wasn't the type of criminal that is prone to commit suicide. 00:13:40.903 --> 00:13:43.739 Even if he was planning to end his life voluntarily, 00:13:43.822 --> 00:13:46.466 he would have done it before he was arrested. 00:13:46.558 --> 00:13:48.661 But he committed suicide after the police investigation 00:13:48.744 --> 00:13:51.038 where they found out that he was a witness. 00:13:51.664 --> 00:13:53.249 What could be the reason for this? 00:13:53.332 --> 00:13:56.293 Could he be playing games until the end? 00:13:57.378 --> 00:14:00.256 He committed suicide without telling us anything. 00:14:00.339 --> 00:14:02.842 If that's the case, he shouldn't have left us anything. 00:14:02.925 --> 00:14:04.802 But, he left a memo. 00:14:04.885 --> 00:14:05.928 What? 00:14:06.804 --> 00:14:08.806 Why on earth did he leave behind a memo? 00:14:09.056 --> 00:14:12.977 And, why did he leave it to Officer Park? 00:14:22.152 --> 00:14:24.738 Why do you suppose Jung Ho-yeong committed suicide? 00:14:25.364 --> 00:14:26.365 Well... 00:14:26.866 --> 00:14:30.578 I'm not sure, but I heard this from a lawyer 00:14:30.661 --> 00:14:32.079 who often visits prisons. 00:14:32.496 --> 00:14:34.456 Some inmates in prison 00:14:34.623 --> 00:14:37.001 can't stand being locked up in a cell. 00:14:38.002 --> 00:14:39.753 Those inmates beg their lawyers, 00:14:39.837 --> 00:14:41.964 and plead to get them out of the cell quickly. 00:14:42.106 --> 00:14:44.066 Some even hurt themselves. 00:14:46.010 --> 00:14:48.721 I suppose he is one of those inmates. 00:14:50.055 --> 00:14:51.515 According to the record, 00:14:51.599 --> 00:14:54.143 he's been locked up in a mental institution. 00:14:54.852 --> 00:14:56.562 The moment he walked into prison, 00:14:56.687 --> 00:15:00.065 he might have been reminded of that memory. 00:15:01.442 --> 00:15:03.510 He can only get out when he dies. 00:15:06.071 --> 00:15:07.865 He couldn't stand being locked up. 00:15:08.741 --> 00:15:11.160 That's why he ended his life with his own hands. 00:15:14.705 --> 00:15:18.208 Sometimes, memories can gobble up a person. 00:15:18.667 --> 00:15:21.170 This has never happened to you, Prof. Shin?

The statute of limitations have expired. 00:20:44.368 --> 00:20:47.663 He could've just stayed quiet. Why risk getting caught again? 00:20:47.746 --> 00:20:50.457 This * must've encountered something to change his mind. 00:20:50.707 --> 00:20:51.917 A trigger. 00:20:52.000 --> 00:20:54.419 Something must've triggered the culprit. 00:20:54.503 --> 00:20:57.506 Otherwise, he would never come out of hiding after 30 years. 00:20:57.589 --> 00:20:59.466 Is it because of the dead Park Gwang-ho? 00:20:59.549 --> 00:21:00.592 What?
