A triple homicide investigation in rural New Mexico has led to murder charges against two step-siblings, with authorities alleging a violent killing followed by an attempt to destroy evidence. While the case has since spread widely across social media and YouTube, official records show that the legal process remains ongoing, with no confirmed convictions as of April 2026.
Background and Discovery
The case centres on a property in Bent, a small community in Otero County, New Mexico. On 22 January 2025, emergency responders discovered a burned blue Subaru on Nogal Canyon Road, roughly a short distance from a nearby residence. Inside the vehicle were human remains later identified as three individuals connected to the property.
The victims were named as:
- Victor Perea, 68
- Mary Mouser, 79
- Killian Mayes, 24
Autopsy findings confirmed that at least one of the victims had suffered a gunshot wound before the vehicle was set alight, prompting a major crimes investigation involving multiple agencies.
Timeline of Events
According to court documents, police affidavits and reporting by Alamogordo Daily News, investigators began piecing together events in the days leading up to the discovery.
- Mid-January 2025: The victims are believed to have been killed at their residence in Bent.
- 20 January 2025: A welfare check request linked to the property raised suspicion after being abruptly cancelled.
- 22 January 2025: The burned vehicle containing human remains is discovered.
- 24 January 2025: Police search a residence in Roswell connected to the suspects, recovering ammunition and items belonging to the victims.
- 27 January 2025: Cassandra Douglas, 28, is arrested in Roswell, New Mexico.
- 29 January 2025: Kane Mayes, 27, is arrested in Mississippi following a multi-state investigation.
Arrests and Charges
According to a 12th Judicial District Attorney’s Office press release dated 5 February 2025, both suspects were served with arrest warrants and formally charged.
Cassandra Douglas faces:
- Three counts of first-degree murder
- One count of conspiracy to commit first-degree murder
- One count of tampering with evidence
Kane Mayes faces:
- Three counts of first-degree murder
- Multiple additional charges including conspiracy, aggravated burglary, arson, and vehicle-related offences
Douglas was held without bond following her arraignment, while Mayes was detained pending extradition to New Mexico.
What Investigators Allege
Authorities allege that the three victims were killed inside the Bent residence before their bodies were transported in Victor Perea’s vehicle, which was later set on fire in an apparent attempt to destroy evidence.
Court filings and local reporting indicate that Douglas told investigators she assisted Mayes after the killings had already occurred. According to those statements, she allegedly helped clean the scene, move the bodies into the vehicle, and dispose of them.
Investigators cited several pieces of evidence, including:
- .22 calibre shell casings found at the scene
- Blood traces and signs of cleaning inside the residence
- Clothing and materials believed to have been used in the aftermath
- Ammunition recovered during a search of the suspects’ residence
Prosecutors have nonetheless charged both individuals with first-degree murder, a charge that can include conspiracy and participation in a criminal act resulting in death under New Mexico law.
Family Relationships Clarified
While early reports and viral content often described the case broadly as involving “family members,” available reporting indicates the victims were primarily relatives of Kane Mayes, including his grandmother, uncle and stepbrother.
Cassandra Douglas is described as Mayes’s stepsister, meaning some widely shared claims that she “killed her own family” are considered misleading based on currently available information.
Online Coverage and Misinformation
The case has gained traction across YouTube, TikTok and podcast platforms, where it is frequently presented in highly sensational terms.
Some videos have used phrases such as “triple killer” or “psycho daughter,” while also misidentifying relationships and overstating the certainty of guilt. In several instances, key details — including ownership of the burned vehicle and the victims’ identities — have been inaccurately portrayed.
Such framing contrasts with official records, which describe an ongoing criminal case based on allegations that have yet to be tested in court.
Current Legal Status
As of the most recent publicly available information reviewed for this report:
- Both Cassandra Douglas and Kane Mayes have been arrested and charged
- Preliminary hearings were scheduled in early 2025
- No confirmed trial outcome, conviction, or sentencing has been identified in official or reliable news sources
Under U.S. law, both individuals remain presumed innocent unless and until proven guilty in court.
What Happens Next
The case remains within the New Mexico legal system, and further developments — including indictments, plea proceedings or trial dates — would typically be recorded through district court filings.
Given the lack of confirmed updates beyond early 2025 reporting, the next major developments are likely to come from:
- Court docket updates in Otero County
- Statements from the District Attorney’s Office
- Verified reporting from local or regional news outlets
Conclusion
The Bent triple homicide case is a serious and complex investigation involving three deaths, a burned vehicle and multiple criminal charges. While the allegations outlined by prosecutors are extensive, the case has not yet reached a confirmed legal conclusion.
For now, the distinction between what is alleged and what has been proven remains central — particularly as online coverage continues to blur that line.
