Las Vegas Backyard NHI Encounter

Briefing

On the night of the thirtieth of April 2023 a bright fireball crossed the skies over the US Southwest and was logged by the American Meteor Society as event #2408, drawing twenty-three independent witness reports across Arizona, California, Nevada and Utah [1]. Roughly an hour after a Las Vegas Metropolitan Police officer’s body-worn camera recorded a bright light streaking overhead, a resident of the city called 911 to report that something had fallen from the sky and that large non-human entities were standing in the family’s backyard [1][2].

The fireball is documented. The beings are not. Officers who attended the address found nothing, the department was unable to determine what had occurred, and the case was closed [2][3]. This file records the case as it stands: a well-attested meteor, an unexplained police call, and a set of witness claims that no primary source supports.

Sequence of events

The thirtieth of April 2023 — evening

• A bright fireball is observed at approximately 06:48 UT on the first of May 2023 — the late evening of the thirtieth of April in local time. The American Meteor Society records twenty-three witness reports across four states, an estimated magnitude between −7 and −18, and two supporting videos [1].
• At approximately 11:50 p.m. an LVMPD officer’s body-worn camera records a bright light — described in reporting as green — streaking across the sky. This occurs before any call about aliens is received [2][3].

The first of May 2023 — after midnight

• Reporting places the 911 call at around 12:30 to 12:50 a.m. The caller reports that something has fallen from the sky and that large entities are in the backyard [2].
• The caller describes the subjects to the dispatcher as “8 foot, 9 feet, 10 foot”, with “big eyes”, a “big mouth”, and “100 percent not human” [2]. This is witness testimony.
• One responding officer tells his partner that he had personally seen something fall from the sky that night. Reporting also captures an officer remarking that he was “so nervous right now… saw a shooting star and now these people say there’s aliens in their backyard” [2].
• Officers search the property and the surrounding area — noted in reporting as roughly eighty miles from Area 51 — and find no creatures, craft, or other unusual evidence [2].
• LVMPD is unable to determine what occurred, does not conclude whether the sky flash and the backyard report are connected, and the case is subsequently closed [2][3].

Documentary record

The American Meteor Society sighting log for fireball event #2408 is the single independently verifiable primary document tied to this case [1]. It establishes that a bright fireball was seen over Arizona, California, Nevada and Utah on the night in question, and it corroborates the timing of the sky flash captured on the officer’s camera. It establishes nothing about the backyard.

The LVMPD 911 audio and body-worn camera footage are official government records generated by the police response. For this file they have been examined only through secondary reporting that quotes and describes them; the underlying records are official, but the versions reviewed here are journalistic reproductions [2][3]. That distinction is material and is preserved throughout.

Angel Kenmore, described in reporting as a Las Vegas teenager, has been publicly named as the 911 caller and as the family member who later spoke to the media and released a cellphone video [3]. She subsequently described the being as “probably around 8 [or] 10 feet tall, very thin”, of “gray, greenish color”, with “weird-looking feet”, adding “I could hear his loud deep breathing” [3]. This is witness testimony offered after the event. The archive notes only that such descriptions overlap with the broader body of Grey-type entity reports; it draws no inference from that overlap.

Scott Roder, a crime-scene reconstruction analyst whom reporting notes worked on the 2014 Oscar Pistorius murder trial, publicly examined the family’s footage and stated that it was “original” and appeared to contain “two creatures” [3]. Roder stated that he “applied the same principles that I would apply to any kind of homicide investigation” and characterised the analysis as open to peer review [3]. His conclusion is a contested interpretation of low-light footage, not an established fact. Sceptical readings of the same footage — including one attributed in reporting to the host of the programme “UFO Witness” — hold that the “creature” is a shadow; this appeared only in search summaries during our research and could not be confirmed against a fetched source [2].

Open questions

1. The primary sources do not establish what, if anything, was physically present in the backyard. Police found no evidence [2].
2. No fetched primary source confirms that the documented fireball, AMS event #2408, is the same object recorded on the officer’s camera, though the timing and the region align [1][2].
3. The exact 911 call timestamp and the LVMPD event or report number were not obtainable from a verifiable primary document during this research. A specific case number circulates informally online; no traceable official record was located.
4. Reporting has claimed that police installed surveillance cameras at the home. This could not be confirmed against any fetched primary or secondary source and is not treated as fact by this archive.
5. A widely repeated claim that a NASA planetary-defence officer characterised the object as more likely a bright meteor than an alien craft appeared in search results but could not be traced to a page successfully retrieved during this research. It is recorded here as unverified attribution and is not cited.
6. No peer-reviewed or official government record — from AARO, the FBI, or NASA — of a non-human-intelligence encounter at this address exists.

Status

This file is CONFIDENTIAL — admitted to the archive on the strength of one verifiable primary record, the American Meteor Society fireball log [1], and two official government record sets, the LVMPD 911 audio and body-worn camera footage, which we have so far reviewed only in journalistic reproduction [2][3].

The tier reflects the documentary record, not the claim. What is documented is a fireball and a police response to a call. What is reported is an officer’s camera capturing a light in the sky before that call was made. What rests on witness testimony alone — and on a contested reading of a family cellphone video — is the presence of eight- to ten-foot non-human beings. That last element clears no evidentiary bar in this archive and is recorded as testimony, not as finding. Officers searched and found nothing.

Updates pending a direct release of the LVMPD 911 audio, body-worn camera footage, and event record.
