A disturbing video recovered during the investigation of a Philadelphia property has reportedly led detectives to a woman who is still alive.

According to investigative sources cited by 6ABC Philadelphia, the recording appears to show Raymond Horsch attempting to strangle a woman with her own necklace.

During the incident, the necklace reportedly broke.

Investigators subsequently located the woman alive.

That development could become one of the most important breakthroughs in the investigation surrounding 417 West Chew Avenue.

For months, authorities have been examining an extensive collection of photographs, videos, chemicals, and other materials recovered from the property.

Some recordings reportedly depict staged encounters.

Others have raised concerns about possible real-world violence.

The newly reported necklace video is especially significant because investigators may now have an opportunity to speak with someone who can explain what happened during one of those recordings.

But the development also comes with an important limitation.

The public reporting does not establish whether the incident was staged, consensual, or criminal.

Nor does it establish that the woman suffered injuries or that an attempted murder occurred.

Meanwhile, another unsettling discovery has attracted attention.

Horsch wrote a book titled Empathy: The Autobiography of a Caring, Compassionate, Empathetic Serial Killer.

A forensic psychologist has examined its contents, including a chapter describing the fictional killing of a woman named Christa and the disposal of her remains using chemicals.

Investigators have also reportedly recovered 21 containers holding an unidentified oily sludge.

The combination of disturbing recordings, fictional writings, missing women, and unidentified substances has generated intense speculation.

Yet the central question remains unanswered.

Can investigators connect any of these materials to an actual crime against an identifiable victim?

A Newly Reported Video Shows an Apparent Strangulation

The latest development centers on footage reportedly recovered from the property.

According to 6ABC Philadelphia, investigative sources described a video appearing to show Raymond Horsch attempting to strangle a woman with a necklace.

The necklace reportedly broke during the encounter.

Authorities later located the woman alive.

That final detail distinguishes this recording from other disturbing footage discussed during the investigation.

A living participant may be able to provide information that video alone cannot establish.

Investigators could potentially learn when the recording was made, why the encounter occurred, and whether the participants understood what would happen.

They could also examine whether the woman suffered injuries and whether any criminal conduct occurred.

However, the transcript does not confirm that she has been interviewed.

It does not identify her.

And it does not disclose what, if anything, she has told investigators.

The discovery therefore represents a potentially valuable investigative lead rather than a confirmed solution.

Why Finding the Woman Alive Could Be So Important

Video evidence can appear straightforward while leaving crucial circumstances unresolved.

A recording may show physical restraint, apparent violence, or a person losing consciousness.

But it may not reveal what happened before the camera began recording.

It may also fail to show what happened afterward.

In some circumstances, investigators must determine whether a recording depicts a staged performance or an actual assault.

That distinction requires more than visual interpretation.

Witness testimony, medical evidence, communications, and other records may help establish the circumstances.

The woman reportedly located alive could provide firsthand information about the necklace incident.

She may also be able to clarify whether other people were present or whether she encountered additional individuals associated with the property.

Those possibilities are important.

But they remain possibilities.

The supplied report does not establish that she witnessed other crimes or knows what happened to any missing woman.

Her identity and potential role in the investigation have not been publicly clarified in the material provided.

Investigators Are Examining More Than One Disturbing Recording

The necklace footage is not the only video attracting attention.

An earlier recording was reportedly described by Philadelphia Police Deputy Commissioner Frank Vanore.

According to the transcript, that footage appeared to show Horsch restraining a woman and placing a zip tie around her neck.

Authorities reportedly described the woman becoming unconscious and appearing lifeless.

The commentator suggested that the woman might have been Nicole Fisero, whose whereabouts remained unresolved in the account.

But that identification was not established.

Nor does the video alone prove that the person died.

The distinction between the two recordings is essential.

In the necklace incident, investigators reportedly found the woman alive.

In the earlier zip-tie recording, the woman’s identity and ultimate fate remained uncertain in the supplied report.

A surviving participant in one recording does not prove that every other recording was staged.

Equally, a person appearing lifeless in a video does not automatically establish a homicide.

Each recording must be investigated on its own evidence.

The Search for Missing Women Remains Central

The investigation has drawn attention because multiple women reportedly had connections to Horsch or the property.

The transcript mentions Nicole Fisero, Gabrielle, Maribel, and other women whose circumstances investigators have been examining.

Some reportedly appeared in photographs or recordings.

Others were associated with the residence and subsequently became difficult to locate.

The precise status of each woman is not fully established in the supplied account.

That uncertainty makes careful reporting particularly important.

A missing person is not automatically a homicide victim.

A person appearing in disturbing footage is not necessarily deceased.

And association with a property under investigation does not establish that a crime occurred against that individual.

Investigators must determine when each woman visited the property, whether she left safely, and what independent evidence exists concerning her subsequent movements.

For families awaiting answers, identifying the women and establishing their circumstances remains a priority.

Raymond Horsch’s Book Adds Another Disturbing Dimension

Investigators and journalists have also turned their attention to a book written by Horsch.

Its title is provocative: Empathy: The Autobiography of a Caring, Compassionate, Empathetic Serial Killer.

Given the investigation surrounding his former property, the title has generated obvious questions.

Did Horsch write a fictional story intended to shock readers?

Did he draw inspiration from people or experiences in his life?

Or could the book contain details connected to actual events?

The transcript describes 6ABC Philadelphia consulting forensic psychologist Katherine Ramsland, a professor at DeSales University who has studied the writings of serial killers.

Ramsland reportedly examined the book and discussed its content.

She characterized the writing as repetitive, sexually explicit, and lacking a clear narrative structure.

Despite its title, she reportedly noted that the narrative describes only one killing.

That observation is significant.

A book describing a serial killer is not evidence that its author committed multiple murders.

Nor does a fictional account become a confession simply because the author later becomes associated with a criminal investigation.

Chapter 45 Describes the Killing of a Woman Named Christa

One chapter has attracted particular attention.

According to the transcript, Chapter 45 describes a woman named Christa.

The narrator portrays himself as someone attempting to help her as her circumstances deteriorate.

The story then describes a purported killing during a sexual encounter.

The narrator rationalizes the act as one of compassion or mercy.

The chapter subsequently describes the disposal of the character’s remains using chemicals.

Those details are disturbing.

But the book was presented as fiction.

The supplied report does not establish that the described killing occurred.

It also does not establish that the character represents an identifiable real person.

Investigators may examine the writing for details that can be compared with physical evidence.

For example, they could look for descriptions of locations, objects, or circumstances that correspond to independently documented events.

But similarity alone would not necessarily establish a crime.

Any connection would require corroboration.

A Real Woman Named Christa Must Not Be Confused With the Book Character

The transcript also discusses Christa Marie Killen, a real woman reportedly connected to Horsch.

According to the account, she knew him for years.

She reportedly appeared in photographs and videos and stayed at the property on different occasions.

Killen died on August 16, 2025, at age 47.

The transcript attributes her death to drug intoxication, citing information reportedly derived from her death certificate.

Horsch had already died earlier that year.

These facts are important because they distinguish Killen’s reported death from the fictional killing described in the book.

The shared first name does not establish that the character was based on her.

It is possible that a writer might borrow a familiar name.

It is also possible that the character was entirely invented.

Neither explanation can be confirmed from the supplied material.

There is no publicly established evidence in the transcript that the fictional Christa and Christa Marie Killen were intended to be the same person.

It would therefore be misleading to present Chapter 45 as an account of Killen’s death.

The Book’s Description of Chemical Disposal Draws Attention

Another passage from Chapter 45 has become relevant to the public discussion.

The narrator reportedly describes using chemicals to break down the fictional victim’s remains in a bathtub.

The narrative then describes disposing of material through a drain.

The detail has attracted attention because investigators recovered chemicals and unusual substances from the property.

Authorities have also examined plumbing associated with the residence.

That combination has encouraged speculation about whether the fictional description could reflect actual conduct.

But the similarities do not establish a connection.

The book reportedly describes a storm drain.

The pipes discussed in the investigation were sewer lines.

Those are not necessarily the same system.

Investigators would need to establish whether any recovered material contains identifiable human biological evidence.

They would also need to determine how it entered the plumbing or containers and whether it was associated with a criminal act.

Without those findings, the book remains a possible investigative reference rather than proof.

Excavated Sewer Pipes Could Hold Important Evidence

The transcript describes investigators examining plumbing outside the house.

Two lateral sewer pipes were reportedly identified as clogged.

One was described as abandoned.

According to the commentator, some evidence associated with the plumbing had already been collected months earlier.

The current reporting therefore should not be interpreted as confirmation that all of the material was newly recovered during the latest search.

Investigators may examine such material to determine whether it contains biological traces or other substances relevant to the case.

However, the transcript does not report laboratory findings identifying human remains in the pipes.

Nor does it establish that the obstructions were caused by criminal activity.

A clogged sewer line can have many explanations.

The significance of the evidence depends on laboratory analysis and its relationship to other verified facts.

Police Reportedly Recovered 21 Containers of Oily Sludge

Another development involves unidentified material recovered from the property.

According to the latest 6ABC report described in the transcript, investigators recovered 21 containers containing an oily sludge.

The substances were reportedly undergoing forensic laboratory examination.

The material’s composition was not publicly established.

It was not confirmed to contain human remains.

No victim DNA identification had been announced in the supplied report.

The transcript also identifies a discrepancy between news accounts.

Earlier CBS Philadelphia reporting reportedly referred to 50 containers.

The later 6ABC account specified 21.

It remains unclear whether the reports described different collections, different counts, or a misunderstanding involving container size.

Until official inventories are available, the discrepancy should not be resolved through speculation.

The important fact is that unidentified substances were reportedly recovered and submitted for examination.

What they contain remains an unanswered question.

What Could Forensic Testing Establish?

Laboratory analysis may help investigators determine the nature of the recovered material.

Tests could potentially identify chemical compounds, biological material, or other relevant substances.

If human DNA were detected, additional analysis might help identify a contributor.

But even that result would require careful interpretation.

The presence of human biological material does not automatically establish a homicide.

Investigators would need to determine how the material entered a container, when it was deposited, and whether it was associated with violence.

They would also need to evaluate contamination risks and the chain of custody.

If the substances contain no relevant biological evidence, that would affect the significance of the containers.

The transcript does not provide results supporting either conclusion.

Consequently, claims that the containers hold dissolved human remains would be premature.

Why Investigators Are Looking Closely at the Property

The investigation has involved an extensive examination of the residence at 417 West Chew Avenue.

According to the transcript, authorities recovered large quantities of digital material and other items.

Investigators have reportedly been working to determine whether the recordings document actual violence or staged activity.

That distinction is central to understanding the case.

The physical search may help establish whether events depicted in recordings occurred at the property.

It may also reveal whether objects, chemicals, or other materials correspond to details visible in the videos.

Investigators reportedly began a second phase of the search involving removal of items and examination of parts of the building.

Heavy equipment was expected to assist as the operation progressed.

The latest reporting, however, did not establish that the necklace video, book, or containers were discovered during the fourth day of the renewed search.

Those materials were previously recovered evidence receiving new public attention.

The Basement Laboratory Is Another Focus

The transcript also refers to a laboratory area in the basement.

Investigators were reportedly dismantling or examining parts of that space.

The commentator suggested that the area may have been connected to the sewer system.

But the supplied account does not establish the exact configuration of the laboratory or the purpose of every item recovered.

The presence of chemicals or specialized equipment can have legitimate and illegitimate explanations.

Determining their relevance requires more than their appearance.

Investigators would need to identify the substances, examine equipment for traces, and compare the results with other evidence.

The laboratory’s significance therefore remains dependent on forensic findings.

Eugene Horsch Has Not Been Implicated in a Homicide by the Reported Evidence

Another important clarification concerns Eugene Horsch, Raymond’s son.

According to investigative sources cited in the transcript, authorities had found no indication that Eugene was involved in the suspected crimes associated with his father.

Eugene’s arrest reportedly helped lead investigators to the property.

He remained in federal custody on firearms-related charges at the time of the report.

But those charges are separate from the suspected crimes being investigated at the residence.

No homicide charge against Eugene was announced in the supplied material.

His family relationship with Raymond does not establish involvement in wrongdoing.

Nor does the fact that investigators may want information from him prove that he participated in a crime.

That distinction is essential to fair reporting.

Raymond Horsch’s Death Changes the Investigation’s Purpose

Raymond Horsch reportedly died in May 2025.

Because he is deceased, he cannot face a criminal trial if investigators later establish that he committed offenses.

That does not make the investigation meaningless.

Authorities may still seek to determine whether crimes occurred.

They may identify victims, recover remains, or establish the circumstances surrounding disappearances.

Those findings could provide important answers to families.

Investigators may also examine whether anyone else committed an offense or possesses relevant information.

But the inability to prosecute Horsch means that a traditional criminal trial against him cannot resolve the allegations.

The investigation’s value may therefore lie increasingly in establishing facts and identifying people who have remained missing.

The Surviving Woman Could Help Investigators Interpret the Digital Archive

The woman reportedly located alive after the necklace incident may be particularly important.

If investigators obtain a reliable account from her, they could compare her recollection with the video.

That might help establish whether the recording depicts an actual assault.

It could also clarify how Horsch organized or recorded encounters.

Investigators might learn whether the woman knew other people connected to the property.

But none of those possibilities has been confirmed.

The transcript does not establish whether she was one of the women previously identified in the recordings.

It also does not establish whether she had contact with Nicole, Gabrielle, Maribel, or any other missing woman.

The strongest conclusion supported by the source is narrower.

Investigators reportedly found a living woman associated with one disturbing video.

That may provide an opportunity to gather firsthand evidence.

A Sensational Book Title Cannot Replace Physical Evidence

The title of Horsch’s book naturally attracts attention.

A work presenting itself as the autobiography of a serial killer sounds alarming when its author is associated with an investigation involving missing women.

But the title is not evidence of serial murder.

The transcript indicates that Ramsland did not describe the manuscript as a verified confession.

Its narrative reportedly contains one killing, despite the title’s reference to a serial killer.

That discrepancy reinforces the need for caution.

Writers can invent characters, events, and methods.

They may also draw from real experiences without accurately describing them.

Investigators must establish which details, if any, correspond to actual events.

A fictional narrative cannot independently prove that someone was murdered.

The same principle applies to disturbing photographs and recordings.

Evidence must be evaluated in context.

What Has Not Been Confirmed

Despite the troubling developments, several important findings remain absent from the supplied report.

Authorities had not publicly announced the recovery of newly identified human remains.

No victim DNA match from the containers had been confirmed.

No laboratory result from the excavated sewer pipes had been publicly established.

No new homicide charge had been announced.

And no additional woman had been officially identified as deceased through the latest evidence described.

These limitations matter because the case has attracted speculation about serial murder and the possible disposal of human remains.

The evidence may eventually support serious criminal findings.

But the transcript does not establish those conclusions.

The investigation remains an effort to determine what happened rather than confirmation that every disturbing possibility occurred.

The Missing Women’s Families Remain at the Center of the Case

Behind the forensic searches and sensational details are families seeking information about women who have disappeared.

For them, the investigation is not primarily about the title of a book or the appearance of unidentified substances.

It is about determining whether their loved ones are alive.

If they are deceased, families deserve reliable information about what happened.

If a crime occurred, they deserve an investigation grounded in evidence.

The uncertainty surrounding the recordings and recovered materials can be especially painful.

Public speculation may create expectations that forensic results will provide answers.

But until testing is complete, the significance of the evidence remains unknown.

Careful reporting can help prevent unverified theories from being mistaken for established facts.

Three Questions Could Determine the Investigation’s Direction

The latest developments leave investigators facing three particularly important questions.

The first concerns the woman found alive after the apparent necklace strangulation.

Can her account establish what happened during the recording and provide context for other evidence?

The second concerns Horsch’s book.

Do any details in Empathy correspond to independently verifiable events, or is the manuscript entirely fictional?

The third concerns the unidentified substances recovered from the residence.

Will laboratory testing reveal material connected to a specific person or criminal event?

These questions are related, but they cannot be answered by assuming that every disturbing detail points to the same conclusion.

Each requires its own evidentiary foundation.

Only then can investigators determine whether the recordings, writings, chemicals, and disappearances are connected.

A Disturbing Investigation Still Waiting for Definitive Answers

The investigation surrounding 417 West Chew Avenue has produced a series of unsettling discoveries.

An extensive digital archive reportedly contains recordings involving disturbing acts.

One newly reported video appears to show a woman being strangled with a necklace.

Investigators subsequently located her alive.

Another recording reportedly shows a woman restrained with a zip tie.

Her identity and fate remain uncertain in the supplied account.

Horsch’s book describes a fictional killing and chemical disposal of remains.

Investigators have recovered unidentified substances and examined the property’s plumbing.

Yet none of those details, standing alone, establishes that Horsch committed multiple murders.

The investigation must still connect evidence to identifiable people and events.

The woman located alive may provide valuable information.

Laboratory testing may clarify the nature of the recovered materials.

And continued searches may help determine what happened to women whose whereabouts remain unresolved.

For now, the most important distinction is between what appears disturbing and what can actually be proved.

The story is not finished because investigators have found a sensational book or troubling footage.

It will move closer to resolution when they can establish what happened to specific women.

And for their families, those answers matter more than any headline.
