The San Pedro Haunting
A violent poltergeist case that was investigated extensively by parapsychologists and featured violent physical attacks on residents.
The San Pedro haunting remains one of the most violent and extensively documented poltergeist cases in American history. For seven years, beginning in 1989, a young mother named Jackie Hernandez and those who tried to help her were subjected to a campaign of supernatural terror that escalated from strange odors and disembodied voices to physical attacks so severe that they nearly claimed the life of a photographer. The case attracted professional investigators, television crews, and documentary filmmakers, all of whom witnessed phenomena that defied rational explanation. What happened in the small bungalow on West Eleventh Street in San Pedro, California, challenged the assumptions of skeptics and believers alike, and left scars---both physical and psychological---that have never fully healed.
A House with History
San Pedro sits at the southern tip of the Los Angeles basin, a working-class harbor community with a long maritime history. The neighborhood where Jackie Hernandez settled in 1989 was unremarkable---modest bungalows lining quiet streets, the kind of place where young families lived because they could afford the rent and where neighbors knew each other by name. The small house Jackie rented gave no outward sign of anything unusual. It was old but well-maintained, with a cramped attic accessible through a ceiling hatch and a narrow crawl space beneath the floor. Nothing about it suggested that it would become the site of one of California’s most infamous hauntings.
Jackie herself was a woman of modest means, a single mother with young children who was simply looking for a safe and affordable place to live. She had no history of involvement with the paranormal, no particular interest in ghosts or hauntings, and no reason to fabricate a story that would ultimately upend her life. By all accounts, she was an ordinary woman placed in extraordinary circumstances, and her initial reaction to the events in the house was not fascination or excitement but bewilderment and fear.
Research into the property’s history revealed that a man named Herman Hendrickson, a sailor, had died in the house decades earlier, reportedly in the 1930s. The circumstances of his death were unclear, but the discovery provided a potential identity for whatever force was at work in the bungalow. Whether Hendrickson’s spirit was truly responsible for the haunting, or whether his death merely added to an atmosphere already charged with negative energy, remains a matter of debate among those who studied the case.
The Onset
The disturbances began almost immediately after Jackie moved in, starting with phenomena that were unsettling but not yet terrifying. Strange, foul odors permeated certain rooms of the house without any identifiable source---not the smell of a gas leak or a dead animal in the walls, but something organic and repellent that seemed to come and go at random. Jackie searched the house thoroughly, checking for plumbing issues, rodent infestations, or anything else that might explain the stench. She found nothing.
Then came the voices. Jackie began hearing sounds that seemed to originate from within the walls or from empty rooms---whispered words she could not quite make out, muttering that stopped the moment she tried to locate its source, and occasionally a distinct male voice that seemed to be speaking directly to her. The voices were accompanied by a pervasive feeling of being watched, a sensation so intense that Jackie found herself unable to relax in her own home.
Objects began to move. Small items---keys, utensils, toys belonging to the children---would disappear from where Jackie had placed them and reappear in improbable locations. Cabinet doors opened on their own. Lights flickered and went out. The phenomena were irritating and disturbing but still within the range of what a determined skeptic might attribute to faulty wiring, settling foundations, or a stressed imagination. Jackie tried to ignore what was happening, telling herself that old houses made strange noises and that she was simply adjusting to a new environment.
The escalation, when it came, was sudden and dramatic. Jackie returned to the kitchen one afternoon to find blood dripping from the walls. Not a thin trickle that might be dismissed as condensation or a leak from the floor above, but thick, dark blood that ran in rivulets down the painted surfaces and pooled on the floor. She screamed, gathered her children, and fled the house. When she returned with a neighbor, the blood was gone. The walls were dry and clean, with no trace of what she had seen.
On another occasion, Jackie saw what she described as a severed human head materialize in her hallway. The apparition was vivid and three-dimensional, the features contorted in an expression of agony, floating at roughly chest height before disappearing as suddenly as it had appeared. The vision left Jackie badly shaken and convinced that whatever was in her house was not merely playing tricks but was actively hostile.
The Investigators Arrive
Desperate for help, Jackie contacted Barry Conrad, a paranormal investigator based in the Los Angeles area. Conrad had been involved in numerous cases of alleged haunting and poltergeist activity, and he approached the San Pedro case with a combination of professional curiosity and healthy skepticism. He brought with him Jeff Wheatcraft, a photographer whose role was to document whatever phenomena might occur during their investigation.
Conrad and Wheatcraft began spending time in the house, setting up cameras and recording equipment, interviewing Jackie about her experiences, and waiting for something to happen. They did not have to wait long. During their early visits, they witnessed objects moving without apparent cause, heard the disembodied voices that Jackie had described, and captured photographs that showed anomalous lights and shadows in areas where no obvious source existed.
The investigators noted that the phenomena seemed to intensify in the attic, a low-ceilinged space that was accessible only through a narrow hatch in the ceiling of a hallway. The attic was hot, cramped, and filled with insulation and old wiring---an unpleasant space under any circumstances. But there was something about it that went beyond mere physical discomfort. Both Conrad and Wheatcraft described a feeling of malevolent attention in the attic, as though something up there was aware of their presence and deeply hostile to it.
It was in the attic that the most terrifying incident of the entire case occurred.
The Attack on Jeff Wheatcraft
During one of their investigation sessions, Jeff Wheatcraft climbed into the attic to set up camera equipment. He was alone in the cramped space, working by the light of a flashlight, when he felt something seize him from behind. Before he could react, a length of clothesline cord was wrapped around his neck with tremendous force. The cord tightened, cutting off his air supply, and Wheatcraft felt himself being lifted and dragged toward the rafters.
Wheatcraft fought desperately, clawing at the cord around his throat, kicking against the floor and walls. He could see nothing that was attacking him---no hands, no figure, no physical presence of any kind. Yet the force that held the cord was immensely powerful, far stronger than any single human being, and it was pulling him upward with clear and terrible intent.
His struggles alerted Conrad and others below, who could hear the sounds of the violent encounter above their heads. They rushed to the attic hatch and hauled Wheatcraft down, finding him purple-faced and gasping, the clothesline cord still wound tightly around his neck. The marks on his throat were vivid and deep, and remained visible for days afterward. Had the rescue come even moments later, Wheatcraft might well have been killed.
The attack on Wheatcraft transformed the San Pedro case from an interesting haunting into something far more dangerous. Poltergeist cases occasionally involve minor physical contact---pushes, shoves, scratches that appear on the skin---but a sustained, deliberate attempt to strangle a person to death was virtually unprecedented. Whatever entity inhabited the bungalow on West Eleventh Street had crossed a line that few hauntings ever approach, demonstrating both the capacity and the willingness to kill.
Wheatcraft, to his credit, continued to participate in the investigation after recovering from the attack, though he understandably refused to enter the attic again. His photographs from the case, including images taken during and immediately after the assault, remain some of the most compelling visual evidence ever produced in a poltergeist investigation.
The Entity Revealed
As the investigation continued, the nature of the entity became clearer, though no less disturbing. The phenomena centered on Jackie Hernandez specifically, following her even when she left the house. When Jackie temporarily moved to a friend’s residence to escape the activity, the disturbances followed her, manifesting at the new location within days. This pattern is consistent with classic poltergeist cases, in which the activity is associated with a specific person rather than a specific place, though the San Pedro case also showed strong ties to the house itself.
Investigators attempted to communicate with the entity through various means, including direct verbal address and more structured approaches. The responses they received were fragmentary and often hostile. The entity seemed to claim a connection to the house and expressed anger at the presence of Jackie and her children. Some investigators interpreted this as the spirit of Herman Hendrickson, the sailor who had died in the house, manifesting his resentment at living people occupying what he still considered his home.
Others proposed different explanations. Some suggested that the phenomena were generated not by an external entity but by Jackie herself, through an unconscious form of psychokinesis triggered by emotional stress. Jackie was under considerable pressure at the time of the haunting---a single mother with limited resources, dealing with the anxieties and frustrations that such a situation inevitably produces. The theory that poltergeist activity is generated by the psychic energy of living individuals under stress has a long history in parapsychological research, and the San Pedro case fit the pattern in many respects.
However, the violence of the phenomena---particularly the attack on Wheatcraft, which occurred when Jackie was not even in the house---argued against a purely psychological explanation. Whatever was happening in San Pedro, it appeared to have an intelligence and a will of its own, capable of acting independently and with lethal force.
Documentation and Media
The San Pedro case attracted significant media attention, both during and after the active haunting. The television program “Sightings,” which was then one of the most popular paranormal shows on American television, devoted multiple segments to the case, bringing camera crews to the house and interviewing Jackie, Conrad, and Wheatcraft at length. The footage they captured, including apparently genuine examples of objects moving without visible cause, reached an audience of millions and made the San Pedro haunting one of the best-known poltergeist cases of the 1990s.
Documentary filmmakers also took an interest, producing longer and more detailed examinations of the case that included forensic analysis of the photographic evidence, interviews with neighbors and local law enforcement, and discussions with academic parapsychologists about the implications of the phenomena. These productions varied in quality and objectivity, but collectively they created an extensive visual and audio record of the case that continues to be studied by researchers.
Barry Conrad himself produced a detailed written account of the investigation, documenting the chronology of events, the methods used to study them, and the evidence collected. His work provides the most comprehensive single source on the San Pedro case and has been cited by numerous subsequent researchers. Conrad remained convinced throughout his life that the phenomena he witnessed were genuine and that the entity responsible was a distinct and dangerous intelligence.
The Long Decline
The haunting did not end with a dramatic climax or a decisive resolution. Instead, like many poltergeist cases, it gradually diminished over a period of years, the phenomena becoming less frequent and less intense until they eventually fell below the threshold of daily notice. The process was not linear---there were periods of renewed activity, flare-ups that recalled the worst days of the haunting, followed by longer stretches of relative quiet.
Jackie Hernandez eventually left San Pedro, moving to a new location where the activity was significantly reduced, though it never ceased entirely. She reported occasional disturbances at her new home---objects moving, unexplained sounds, the persistent feeling of being watched---but nothing approaching the violence and intensity of the San Pedro years. Whether the entity had exhausted itself, whether Jackie’s own psychic energy had stabilized, or whether the simple act of leaving the house had broken whatever connection bound her to the phenomena, the worst was over.
The bungalow on West Eleventh Street passed to new occupants, and reports from subsequent residents have been mixed. Some have reported minor disturbances---cold spots, strange sounds, an uneasy feeling in the attic---while others have lived in the house without experiencing anything unusual. The attic, where Jeff Wheatcraft was attacked, remains a deeply unpleasant space, though whether this is due to supernatural influence or simply the cramped and stifling conditions of a small attic in a Southern California summer is impossible to determine from the outside.
Legacy and Significance
The San Pedro haunting occupies an important place in the history of American poltergeist research. The case combined many of the classic elements of poltergeist activity---a focal person under emotional stress, escalating phenomena, physical attacks on individuals---with a level of documentation that exceeded most comparable cases. The involvement of professional investigators, the extensive photographic record, the television coverage, and the corroborating testimony of multiple independent witnesses created a body of evidence that is difficult to dismiss, even for determined skeptics.
The attack on Jeff Wheatcraft remains the most disturbing aspect of the case and one of the most violent incidents in the annals of poltergeist research. The physical evidence---the marks on his neck, the cord that was used to strangle him, the testimony of those who pulled him from the attic---is consistent with a sustained physical assault by a force of considerable strength. That no attacker could be seen, that the assault occurred in a confined space where no human being could have hidden, and that it was witnessed by multiple people who saw Wheatcraft struggling against nothing visible, defies conventional explanation.
The San Pedro case also raises important questions about the nature of poltergeist phenomena more generally. The fact that the activity followed Jackie Hernandez when she left the house suggests a connection to the individual rather than the location, while the intensity of the phenomena within the house itself suggests that the location also played a role. This dual nature---person-centered and place-centered simultaneously---is characteristic of some of the most severe poltergeist cases and suggests that the phenomena may arise from an interaction between the psychic state of the individual and the spiritual properties of the environment.
For Jackie Hernandez, the seven years of haunting left lasting effects. She endured experiences that would have broken many people---years of fear, disruption, and physical danger in her own home, coupled with the skepticism and sometimes outright ridicule of those who doubted her account. That she survived the ordeal and rebuilt her life is a testament to her resilience. That the events she described have never been satisfactorily explained is a reminder that the world contains phenomena that lie beyond the reach of our current understanding, waiting in dark attics and empty rooms for those unfortunate enough to encounter them.
