Bloody Field Trip Case

* Fin Fennec (BLUE; in charge)
* Hirsch (BLUE; autopsies)

The **Bloody Field Trip Case** (『血 の 実習 事件』, *Chi no jisshū jiken*) is a murder case that happened five years ago. It is the case that got Ron Kamonohashi expelled from BLUE and made him lose his detective license.

Apart from being a prominent historical case, it is the 23rd main case in the *Ron Kamonohashi: Deranged Detective* series.

## Overview

Five years ago, on October 1, the first-year student Ron Kamonohashi was chosen for a practical exercise to work alongside the police to catch a group of seven assassins; at that time, it was London's biggest case. Ron cracked the criminals' code and located their hideout in an isolated factory. Following his own judgment, he headed there alone at 4 p.m.

When the police arrived at the hideout one hour later, they found Ron standing in the middle of the murderers' corpses. He was holding a knife and was covered in blood but seemed completely calm. As he was injured all over his body, he was subsequently taken to the hospital where he underwent treatment for three hours; Ron has no memories of that time. After he healed, only a scar in the shape of a "96" remained on his neck.

Because Ron has no recollection of the period thirty minutes before and after the incident, it was ruled that Ron had been in a state of temporary insanity. He could, thus, avoid the death penalty, but was expelled from BLUE and his detective license was revoked.

### Classified case file details

Three days before the practical investigation, Ron was chosen for it; by that time, he had already solved the case. To pass the time until the exercise, Ron asked Fin Fennec for one of her locked room cases to solve, and she gave him a particularly difficult one which she herself had not solved yet. Elmer Stingray transferred to BLUE on the same day and got interested in Ron although Ron only ignored him.

When Ron went to buy some brown sugar syrup from the school shop, he learned that Shachi had bought them all. Ron asked for a package, and Shachi handed one over. Afterward, Ron went to a basement room to ponder over the locked room mystery in peace. He wracked his brain over the case, sipped on his syrup, and eventually collapsed from exhaustion. On the day of the practical exercise, Ron finally solved the mystery. He dropped off his homework in Fin's mailbox before he went to meet Scotland Yard. Two hours later, the incident happened.

While everyone else was still in class, Ron hurried to the hideout and arrived by 4 p.m. He waited for the police. However, he found a children's shoe by the factory, and when he heard a child's cry from within the hideout, Ron rushed inside and right into a trap as the cry was a recording. The group of criminals attacked Ron, and when one of them took out a knife, Ron blacked out. Ron woke up one hour later among the murderers' corpses. Shortly afterward, the police arrived and detained him.

Fin was put in charge of the case, likely because the crime scene seemed to be a locked-room scenario. The factory could only be reached and entered via one road. It was impossible to enter from the back (there was a river behind the building) or through a window (they were six inches square and too narrow for a person). As only Ron had been sighted coming down that road, Fin determined that no one but Ron had entered or left the factory. Fin also noted that Ron did not "feel like his usual self" the day of the incident.

Hirsch autopsied the bodies and estimated their times of death between 4 and 5 p.m., the one hour in which Ron had been unconscious. There was no sign that the corpses had been moved. While the victims were killed in a generally impressive manner, the culprit missed to stab one directly in the heart. Further, an unknown third party's blood was discovered on Ron's vest.

Furthermore, right after the incident, Elmer disguised himself as an officer to gain access to the case file. This was caught on camera.

## History

### New investigation

Following the Island Observatory Murder Case, Ron deduces that the Bloody Field Trip was a set-up as both cases were deliberately similar: He was discovered at the crime scene with no memory of what happened and was accused to be the killer. Beneath Kayoko Onodera's corpse, someone had also drawn "96" in red ink. Ron then declares that he will not forgive whoever stole five years of detective work from him and decides to look into the case again. Previously, John Grizzly also expressed the wish to re-open the case.

Ron eventually manages to get a copy of the case file from Scotland Yard, though it does not contain the information he wants and needs.

Later, Aimee Emmerich reveals to Ron, Totomaru Isshiki, and Spitz Feier in a message that blood was found at the crime scene that belonged neither to Ron nor to any of the victims. Although this showed that a third, unknown party was involved in the crime, it could not provide any new answers to the case, and Ron's suspicion could not be cleared. This detail was deleted from the case files at BLUE before the case was later completely deleted from the school's and the police's records.

Furthermore, Ron's "96"-scar is not, as he had believed, a remnant of the injuries he sustained during the incident. Instead, he received the scar while he underwent medical treatment for his injuries; his Kill on Sight ability was implanted with it.

Aimee thinks the M. Family was behind the Bloody Field Trip. However, because she has learned there is an M. Family spy at BLUE, she can neither re-open the investigation nor openly help Ron; still, he has her support. During the Plateau Auberge Serial Murders Case, Mylo Moriarty confirms that the spy modified Ron's body and gave him Kill on Sight. He also says that Ron will meet the spy "in the near future."

### Possible culprits

After the Twin Prison Locked Room Murder Case, Fin Fennec informs Ron that, last year, she stopped by the Bloody Field Trip's crime scene and spotted Aimee entering it. She noticed Hirsch tailing Aimee and confronted him about his presence. He claimed he was only there to check whether he left anything at a crime scene he had worked on. Because he was surprised to see Aimee, he stuck around without calling out to her. Fin later checked the documents and learned that Hirsch was not in England when the Bloody Field Trip happened and should, thus, have nothing to do with the case. The information that Hirsch was not in the country at that time is "off the record."

Following the Coin and Carving Murders Case, Hirsch confides to Ron and Toto that he conducted the autopsies in the Bloody Field Trip Case. On the day of the incident, he was vacationing in the mountains when he got a call from the police about the homicide. Hirsch examined the corpses and found nothing of note; they were, however, very precisely and strategically killed: Vital points were stabbed and they died instantly.

Hirsch adds he is only interested in the case because of the deleted data and the rumor that was spread afterward that he was overseas. He denies having any connection to the case and seemingly did not know about the M. Family's involvement before Ron told him. Furthermore, Hirsch discourages Ron from investigating any further and says that whoever told him about the rumor might be working for the M. Family.

Not long afterward, Toto and Ron encounter Elmer Stingray who claims to know Ron from BLUE. Elmer states he transferred to BLUE three days before the Bloody Field Trip Case. After Ron treated Elmer's injuries once, they became friends; Ron even agreed to be investigative partners. Ron, however, has no recollection of that. Elmer came to Japan after searching for Ron for the last five years.

### An invitation and a chance

After the Obon Dance Murder Case, Ron receives an invitation from Mylo for a test on a cruise. Winter Moriarty also delivers the unedited Bloody Field Trip Case file to Ron. The file contains the missing blood type data and several testimonies from people connected to BLUE, i.a. Fin, Shachi, Hirsch, and Elmer. Ron does not doubt the file's authenticity as he knows Winter plays fair.

By comparing the testimonies and statements, Ron can reconstruct his situation five years ago, starting from three days before the incident. Considering everything, Ron comes up with four possibilities:

Fin could have lied about the crime scene being a locked room to hide some trick. Hirsch could have falsified the times of death to conceal that the assassins had been killed elsewhere. Shachi could have laced the brown sugar he gave Ron with a hallucinogen. Elmer might have tampered with the official file to incriminate Ron.

With all this new information, Ron is ready to find the true culprit in the Bloody Field Trip Case.

### Culprit hunt and truth

*Main article: Tragic Cruise Serial Murders Case*
Aboard the *Precious Dolphin*, Ron has to investigate a series of murders that will bring him closer to finding the informant. After preventing the third murder, Ron and Toto are knocked unconscious. Ron later wakes up in the Precious Hall in the audience of a magic show; Toto has vanished, and the four suspects are asleep in the front row.

When the magician pulls out the gun Mylo left Ron, Ron rushes on stage and retrieves it. Mylo's mechanic teddy is then lowered down on a rope, and Mylo tells Ron that it is time to identify and shoot the culprit. Ron points the gun at Fin but it is only a ruse to force Shachi into exposing himself. Ron figured out that Shachi must be the spy because everything he did diverted attention away from Fin.

Ron also solved the Bloody Field Trip Case: Shachi laced the brown sugar syrup he gave Ron with a sleeping drug. After Ron drank it and fell asleep, Shachi changed the date on Ron's phone by a day. Thus, when Ron woke up, he believed three days had passed, not two, and headed to the factory where he lost consciousness.

To ensure that people thought Ron was still on campus, an impostor filled in his place. He walked around school and even treated Elmer when he got injured; in the process, blood splattered on the impostor's vest. Because Ron distanced himself from the other students, nobody realized saw through the disguise.

On October 1, Shachi resubmitted Ron's homework—prompting Fin's remark that Ron did not "seem like himself" as he took three instead of two days to solve the mystery—and the impostor went to the factory. The impostor killed the six murderers, dressed Ron in his bloodstained uniform, and disposed of his mask before he stabbed himself and handed Ron the knife with his last strength. The impostor was the one who was not stabbed through the heart and died instantly.

After hearing all that, Shachi admits that he is the M. Family informant who ruined Ron's life. Mylo later shoots him for his failure.

### Aftermath

Spitz reports everything to BLUE. After Aimee passes on the information to the World Detective Alliance, they rescind Ron's punishment. He is now eligible to retake the test to get a detective license. Ron also receives his diploma and formally graduates from BLUE.
