Case

Situation

Kogoro had just solved a case of running away from home due to failing the entrance exam, which was actually thanks to Conan finding a photo of the missing person on the internet. The Mouri family decided to go eat in Gunma prefecture, but Kogoro didn't believe what Conan had just looked up on the internet and decided to ask Yamamura, while Ran grumbled in her mind that they found the person thanks to the internet.
However, as soon as she heard that Kogoro was in Gunma, Yamamura asked him to come because at the crime scene on the border of Gunma and Nagano, there were three Nagano police officers who looked scary to Yamamura, whom the Mouri family recognized as the police trio Taka'aki Morofushi, Kansuke Yamato, and Yui Uehara after they arrived.

Resolution

  Show spoilers »

The culprit is Yumi Nakata. Yumi had used a trick to make it look like she was still in her apartment when in reality, she was in the parking lot beating Kazuki Tsukishima to death. Yumi set up a towel on a Ring light and tied a rubber band on the top to mimic her hair bun, she then placed the Ring light on top of a luggage case to match her height.

She then tied a string connected to her curtain and attached the other end to her first cellphone and set it on the edge of a table next to the window. After she murdered Kazuki, she dialed the number of her first cellphone with her second one, which caused the phone to fall off the table pulling the curtain open. This gave the illusion that she had opened her curtain to peer outside, which was also captured on the surveillance camera.

Yumi used a blackjack to kill Kazuki, it involves placing a heavy object into a sock and swinging it with enough force to kill someone. She used Kazuki’s sock and an object of her own to create a blackjack. Detective Kansuke deduces that she had hidden the object in question in her hair bun, he noticed this as Detective Uehara also had her hair in a bun, but she has longer hair. While a photo revealed that Yumi’s hair was shoulder length, which meant that she did not have enough hair to tie it into a bun. Uehara undos her hair, which reveals a wrist weight that was hidden in her hair bun.

Motive

Detective Uehara asks why she didn’t just discard the evidence, but she didn’t have the heart to as the wrist weight was given to her by Chizu Yuba. Chizu had given to her as she did not have time to exercise or go to the gym.

Kyouko and Senta ask why she killed Kazuki and she reveals that she did it in revenge for him causing the death of Chizu’s mother and for putting Chizu into a coma. Years ago, the four of them Kazuki, Kyouko, Senta, and Yumi all came across a car accident, where Chizu and her mother were trapped in their car that was hanging off a steep cliff. They quickly managed to save Chizu, however the car ended up falling down the cliff killing her mother. However, Yumi found it strange as she knew they had enough time to save both of them and yet they failed.

Years later she learned the truth, Chizu had been looking around Kazuki’s laptop and found a video that he recorded of that fateful day. The video revealed that when Kyouko and Senta was attempting to save Chizu’s mother, Kazuki stopped them and told them that it would be better to save her when the ambulance came as it would look more heroic. However, as they were discussing this, the car ended up falling down the cliff which lead to Ms. Yuba’s death. Horrified that she had been lied to, Chizu recorded a copy of the video on her phone and sent a copy to Yumi, who was just as shocked after learning the truth.

Chizu confronted Kazuki with the video and out of fear he chased her to the stairs, where she fell and was left in a coma. After Yumi learned the truth, she intentionally invited Kazuki, Senta, and Kyouko to the hotel to kill Kazuki in revenge. She also intended to frame Kyouko and Senta for his murder as she also held the two of them responsible for what happened to Chizu and Ms. Yuba.

Yumi believes that if she hadn’t kept the wrist weight, she could’ve have gotten away with the murder. However, Detective Kansuke reveals that it would have not mattered as Kazuki with the last of his strength left a dying message with his own body. He positioned his body along the border between Gunma and Nagano to reveal the identity of his killer. He positioned his body to mimic Kanji and with the line going down the middle of his body, it spelled out her entire name: Yumi Nakata.

Aftermath

Yamamura wonders why Hiro calls their shared base his home, which Conan explains when the entrance sign dangles and some other conditions along, double down the sign and you get the word Misao. Next, Yamamura mentioned that he received a strange postcard 5-6 years ago saying that they would come to his house. He waited all day there but no one showed up.
Then Taka'aki asks about that secret base and they all go there and explain about the letter. After flipping the entrance sign to Misao, we can see that Hiro has become a police officer like Yamamura, but Yamamura is sad that Hiro gave up on his dream. Taka’aki encouraged him and explained that Hiro had been promoted to the police security force, so he could not keep in touch with his relatives and friends to ensure his identity.
In the end, Taka’aki hasn't revealed his brother’s death to Yamamura because, after all, Hiro was a dear friend of his, and he wants to keep his hope that both of them are currently serving justice.
