The general contents of the letter are confessions about incriminating evidence and begging for mercy from the recipient.
The person who wrote the letter wished to hand over the most valuable thing in the person's possession to the recipient. In doing so, the person asks for forgiveness, only hoping that the other party will not make the bullying public.

The following is printed on the note:

"If you don't wish to lose your current home, do exactly as I tell you."
"Don't tell them about your current situation. Act like nothing's happened. Don't reveal anything."
"Don't let them in your room. No one can go in."
"Don't call Dad 'Dad,' Don't call Mom 'Mom,' and certainly don't call Grandma, 'Grandma.' Your family doesn't like to be called that."
"Don't tell them what's bothering you. Tell them what you need."
"Take your medicine on time."
"If you encounter a problem that you can't solve, write it on a note. There is a small hole in the pagoda tree in the backyard. Put it in there, and someone will come help you."
"Important! Be sure to go to sleep before midnight. Even if you can't fall asleep, don't leave your room, no matter what you hear outside."

Theory 1: According to handwriting analysis, it is confirmed that the person who wrote the letter was Jill Meadows' grandson, Billy Chante.

1. At first, Jill Meadows was extremely grateful to Letha Graye for taking her in. However, when she found her grandson's watch, as well as his handwritten letter of repentance in Letha Graye's bedroom, she was certain that Letha Graye was involved in her grandson's suicide.
2. Aside from Letha Graye, Jill Meadows also believed Angela Diggs to be responsible for slandering her grandson. She claimed that she never wanted to murder Letha Graye, only to make her suffer a little. To that end, she poisoned Letha Graye with a pesticide of minimal toxicity and framed Angela Diggs in the process.
3. Jill Meadows claims that on the night of the incident, she was locked in a closet by Letha Graye. later, she fled the room in a hurry after regaining her freedom. Before, Letha Graye had handed her a note, but she flushed it down the toilet in a panic.
4. Jill Meadows admitted that her previous statement of an argument between Letha Graye and Hugo Graye was false. They had not met before the case, and she knew that Hugo Graye was intellectually disabled.
5. Jill Meadows claims that Letha Graye had undergone significant changes in her personality recently. She was much quieter than before and spoke with hesitation about Mavis Sutcliffe's disappearance. Her reaction, however, wasn't one of sadness.

A notebook filled with many incorrect math problems, almost half used up.
The second page has indentations left by writing. Considering that the torn preface page was used to fill in names, it is suspected that important information was written in haste, and then torn off to be passed on.

Theory 1: Rubbing over the indentations reveals what was written on the first page:
Granny, help me.

Victim: Letha Graye
Cause of Death: Pesticide poisoning followed by viral encephalitis.
Time of Death: Early in the morning 2:00~4:00
Notes: Non-fatal pinch marks on the neck, which, based on the direction and force of the marks, could have been subconsciously caused by Letha as she struggled with the burning sensation caused by pesticide entering her throat.

Theory 1: Letha Graye was already suffering from viral encephalitis before ingesting the pesticide.

Theory 1: It is presumed that the person who left the note was Letha Graye before she lost her memory.

1. Opaline River Laboratory was established in 2027 by Tyson Turner and used for developing an "immortality" drug. It was closed for some reason during the first half of this year, but following Tyson's illness, it was hurriedly reopened to work on developing an anticancer drug. Later, the lab burnt down during a fire, and what exactly it was being used for at the time remains unknown.
2. Irene Burke once witnessed Tyson Turner and Simon Bloodworth arguing on the rooftop, and heard them mention "controlled materials" and an "immortality drug". Simon demanded a large amount of hush money from Tyson.
3. Tyson Turner travels on a cruise twice a year and forges his account expenses on return. He's suspected of spending money on the lab to hire workers and purchase materials.
4. Tyson Turner once gave a picture of Vyn to Irene Burke, insisting that she find a way to get rid of him. An enormous sum is transacted out of his account every so often.
5. Tyson Turner knew the members of the previous NXX Investigation Team but is unaware that Artem is now one of them.

The video is divided into 3 parts:
In the first part, Simon Bloodworth briefly introduces himself briefly and confirms Jovi Vance's guess about his father's cause of death. He admits to having illegally sold controlled substances to Gordon Grant, and says that he received death threats from Tyson Turner because of this. The reason Tyson was so afraid of him was that he'd stumbled across a secret that should never have come to light.
In the second part, Simon mentions that Tyson brought a batch of raw material in 2026 and demanded Simon illegally bring them in as part of a relatively large product line. The line in question was later split into three different lines, with target customers including Stellis customers, VIP customers and a certain segment of youth. Simon instead sold part of this batch of materials to Gordon Grant, which reveals that he thought they were subpar materials being passed off as good quality, whereas in reality, they’re able to provide longevity and anti-aging effects. This particular batch of materials was especially effective, and was bought by someone called "Lowe".
In the third part, Simon explains in detail how he helped Tyson forge the inventory records in order to illegally bring in the raw materials. He even includes the true inventory records, properly arranged, at the end for future viewers’ convenience. Finally, he makes a request to Jovi Vance, saying that if he disappears from this world one day, to give everything in his bags to the police, and make public everything Tyson Turner has done.

Simon Bloodsworth created false inventory records to help Tyson Turner bring in controlled materials. The last thing among the records is an original, unmodified version that contains a detailed summary of the raw material product batch numbers, entry and exit volume, inventory stock, time received and similar information.

A research notebook was found in Lowe's residence. The earliest record is dated 2026.
Apart from some scattered letters and numbers, there are a lot of chemical formulae. The research mentions "NXX's active properties" and "matched with a research method that ensures stability..." Hold on, this seems to be related to NXX.

Some papers were discovered in Lowe's residence. They include reports on the "samples" in Opaline River Laboratory, and contain data on the physical condition of each observation target during different stages of the experiment.
One of the pages includes a report on Hugh Moss' data and physical condition. His name has been marked with a red star.
