Yu Menglong died in Beijing on September 11, 2025, at age 37 after a fatal fall. His management, his mother and Beijing police publicly described the death as an alcohol-related accident and said criminal involvement had been excluded. The online clip described as Yu’s alleged screaming video has not been authenticated as footage of him, so it does not prove torture, murder or a cover-up.
Yu Menglong, also known as Alan Yu, died in Beijing on September 11, 2025, at age 37 after a fatal fall. His management, his mother and Beijing police all publicly described the death as an accidental fall after alcohol consumption, and police said criminal involvement had been excluded. The video described online as an alleged recording of Yu screaming has not been authenticated as footage of him and should not be presented as evidence of torture, murder or a cover-up.
The clip intensified an already volatile online debate. Fans and other users questioned whether the official account was sufficiently transparent, while unverified videos, alleged eyewitness accounts and conspiracy claims circulated widely. But public suspicion is not the same as independently verified evidence.
Reporting basis: The account below follows the publicly reported statements and reporting cited in the research dossier, including the September 11 management announcement, the September 16 statement attributed to Yu’s mother through his agency, the September 21 Beijing police notice, and reporting by CNA, AsiaOne and AFP.

| Date | What was publicly reported |
|---|---|
| September 11, 2025 | Yu Menglong’s management announced his death in Beijing after a fall. The announcement said police had ruled out criminal involvement. |
| September 16, 2025 | Yu’s mother issued a statement through the agency. She said he had consumed alcohol and accidentally fallen to his death, and asked people to stop spreading speculation. |
| September 21, 2025 | Beijing police said the death was an alcohol-related accidental fall and that criminal suspicion had been excluded after investigative work. Police said the investigation included scene examination, forensic work, witness interviews and a review of surveillance footage. They also said individuals had been investigated or punished for fabricating or spreading false information. |
Those statements are the publicly reported account of what happened. They should not be confused with three separate independent investigations: the management announcement and the family statement repeated the family’s account, while the police notice described the authorities’ conclusion and investigative steps.
What is known about the alleged screaming video?
A clip circulated online with claims that it captured Yu Menglong screaming or pleading for help. The reviewed reporting found no authenticated provenance for the material. No reliable source established that the voice belonged to Yu, that the person shown was Yu, or that the clip was recorded at the time and place of his death.
Several basic questions therefore remain unanswered:
- Who originally recorded the video?
- When and where was it recorded?
- Is there an original, unedited file, or only copies and reposts?
- Were the audio and imagery captured together, or were they combined later?
- Who is heard or shown in the clip?
- Does the scene depict a genuine event, unrelated material, a staged recording, an edited clip or a miscaptioned video?
Without a reliable chain of custody or independent authentication, the clip cannot establish what happened to Yu. The careful description is an unverified video circulated online and intensified suspicions. It is not accurate to write that Yu can be heard screaming, that the video shows him being tortured, or that it proves he was murdered.
Even a genuine recording of someone in distress would not automatically identify the speaker, establish the date or location, or prove the cause of a later death. Those conclusions require corroboration from evidence such as the original file, verified location information, reliable witnesses, forensic findings and an independently established timeline.
Why the story generated such intense suspicion
The death was sudden, Yu was young and widely known, and the official conclusion came quickly. Many fans viewed the initial explanation as insufficiently transparent and demanded more answers. That distrust created favorable conditions for emotionally powerful but poorly sourced material to spread.
Online repetition can make a claim appear confirmed even when every post traces back to the same unknown upload. A caption asserting that a sound is Yu’s voice may be copied thousands of times without anyone independently testing the assertion. The emotional force of a scream can also cause viewers to treat their reaction to a clip as proof of its context.
It is reasonable to report that fans suspected foul play, questioned the official account and expressed anger online. It is not reasonable to turn those reactions into evidence that coercion, assault, torture, murder or a cover-up occurred.
Viral claims and what the available evidence supports
| Claim | What can responsibly be said |
|---|---|
| The video captures Yu Menglong’s voice. | No reviewed reliable source authenticated the voice or established the identity of the person in the clip. |
| The video proves torture or murder. | No. The clip’s provenance, date, location, identity and editing history were not established. |
| Yu was killed in a cover-up. | This remains an allegation. It is unsupported by independently verified evidence in the reviewed reporting and conflicts with the publicly reported police conclusion. |
| Posts were deleted, so the allegations must be true. | No. Moderation, censorship, rumor enforcement and ordinary platform takedowns can all affect what users see. A removed post does not prove either the allegation or a cover-up. |
| A viral protest video proves mass demonstrations occurred. | AFP documented at least one separate purported protest video that was AI-generated, including visible Sora watermarks and distorted figures. That finding does not establish that every protest image was fabricated, but it demonstrates why individual clips require verification. |
Separate fabricated material made the wider controversy harder to assess
The alleged screaming clip was not the only piece of questionable material connected to the online uproar. AFP reported on a widely shared video presented as footage of public protest. Researchers identified signs that it was AI-generated, including Sora watermarks and distorted characters.
That example matters because unrelated or fabricated material can be folded into a real event and then used to reinforce a preferred narrative. It does not prove that every account from fans was false, nor does it by itself authenticate or disprove the alleged screaming video. It does show that virality, apparent emotion and large numbers of reposts are not substitutes for provenance.
How to check an alleged viral video before sharing it
Anyone assessing the clip—or a similar video—should work through the evidence rather than the caption:
- Locate the earliest available upload. Record the original account, upload time, accompanying description and any claim about where the footage came from. A repost is not an original source.
- Look for the complete file. Short excerpts may omit an introduction, interruption or context. Save the exact version being examined, while avoiding unnecessary redistribution of graphic material.
- Check whether the audio and video belong together. Listen for abrupt cuts, mismatched background noise, repeated sounds or changes in acoustic space. Audio-video synchronization should not be assumed.
- Compare visual details with independent images. Buildings, windows, roads, weather, lighting and other landmarks can help test a location claim. They cannot establish identity by themselves.
- Search key frames and distinctive phrases. Reverse-image searches and searches for earlier captions may reveal that the footage predates the event or came from another country or incident.
- Treat metadata cautiously. Metadata can be stripped or changed when a file is downloaded, edited or uploaded to a platform. Its presence is potentially useful, but it is not automatically proof of authenticity.
- Demand independent corroboration. Look for named witnesses, contemporaneous records, verified location data, consistent reporting and official documents. Multiple accounts are not independent if they all copy one anonymous post.
- Separate evidence from interpretation. A clip may show a person shouting; that does not establish who the person is, why they are shouting or how the footage relates to Yu’s death.
For sensitive death reports, the safest practice is not to embed graphic or unverified material unless there is a clear public-interest reason and the source can be independently established. Repeating an unverified claim in a headline, caption or social post can amplify it even when the article later qualifies the claim.

Yu Menglong’s career
What can be stated without overstating the evidence
The most accurate summary is:
Yu Menglong died in Beijing on September 11, 2025, after a fatal fall. His management, his mother and Beijing police publicly described the death as an alcohol-related accident, and police said criminal involvement had been excluded. An alleged screaming video circulated online, but no reviewed reliable source authenticated it as footage of Yu or established its context. Fans’ doubts and the resulting online uproar are real as a matter of public reaction; they are not independent proof of murder or a cover-up.
Based on the evidence reviewed for this account, no verified material overturns the publicly reported police conclusion. That conclusion can be questioned as a matter of public accountability, but questioning it is different from proving the alternative.
Frequently Asked Questions
Was the alleged screaming video proven to show Yu Menglong?
No. The reviewed reporting found no reliable authentication of the voice, the person shown, the recording date or the location. It should be described as an unverified clip, not as evidence that Yu was screaming.

What did Yu Menglong’s family and Beijing police say happened?
Yu’s management announced his death after a fall on September 11, 2025. His mother later said he had consumed alcohol and accidentally fallen, and Beijing police subsequently described the incident as an alcohol-related accidental fall and said criminal suspicion had been excluded.
Do deleted social-media posts prove that authorities covered up Yu Menglong’s death?
No. Posts can be removed for many reasons, including platform moderation, censorship, rumor enforcement or ordinary policy violations. A takedown does not independently establish either the truth of an allegation or a cover-up.
Was the viral protest footage connected to the controversy authentic?
AFP reported that one separate video presented as protest footage showed signs of being AI-generated, including Sora watermarks and distorted figures. That does not prove every protest image was fabricated, but it shows why each video must be checked separately.
The Bottom Line
The alleged screaming video should be treated as unverified material, not as proof that Yu Menglong was tortured or murdered. The publicly reported family and police accounts describe an alcohol-related accidental fall, and no independently authenticated evidence reviewed here establishes foul play.
