As of June 2026, Heriberto "Eddie" Seda remains incarcerated at a maximum-security facility in New York State. He is 58 years old and is serving a 232-year sentence for his crimes. Due to the consecutive nature of his sentencing, he will not be eligible for parole until the year 2231, ensuring he will spend the rest of his life in prison.
Between 1990 and 1993, a wave of terror gripped New York City. A serial attacker, mimicking the infamous and unidentified California killer of the 1960s, began targeting victims based on their astrological signs. Leaving behind cryptic notes, maritime signal flags, and a trail of victims shot with untraceable homemade weapons, the "New York Zodiac" baffled law enforcement for years.
The man behind the moniker, Heriberto Seda, was eventually captured not through complex psychological profiling, but following a violent domestic dispute. Decades later, the case remains a subject of intense public interest, fueled by recent true-crime documentaries and the passing of key figures involved in the investigation. This article provides a comprehensive 2026 update on Seda's status, the legacy of the detectives who caught him, and the intricate details of one of New York's most notorious criminal investigations.
Yes, Heriberto Seda is still alive. Born on July 31, 1967, Seda is currently 58 years old. He has spent nearly three decades behind bars since his arrest in the summer of 1996. Following a lengthy trial, he was convicted of three murders and multiple attempted murders, resulting in a staggering sentence designed to keep him permanently removed from society.
Seda was handed a 232-year sentence by the New York State judicial system. To the layperson, a sentence extending centuries into the future may seem unusual, but it is a specific legal mechanism used to ensure a defendant can never be released. In New York, judges have the discretion to mandate that sentences for multiple distinct crimes be served consecutively rather than concurrently.
Because Seda was convicted of multiple separate counts of murder and attempted murder, the judge stacked the penalties. According to reports detailing his incarceration status, this consecutive sentencing structure means Seda's official parole eligibility date is set for the year 2231. He would need to live to be 264 years old to even be considered for a parole hearing. Consequently, his status is effectively a permanent life sentence without the possibility of release.
The story of the New York Zodiac cannot be told without highlighting the law enforcement professionals who worked tirelessly to end the spree. On September 30, 2025, the law enforcement community mourned the loss of Detective Joseph Herbert, who passed away at the age of 68. Herbert was the pivotal figure who ultimately connected Heriberto Seda to the Zodiac crimes.
For years, the NYPD had collected letters from the killer, analyzing the handwriting, the astrological symbols, and the taunting tone. When Seda was arrested in 1996 for an unrelated domestic incident, he was required to write a statement. Detective Herbert, who had spent countless hours studying the Zodiac's letters, was reviewing Seda's written confession.
Herbert noticed distinct idiosyncrasies in Seda's penmanship. Specifically, Seda had a unique way of forming the letters "s" and "t," and he habitually underlined certain words for emphasis—traits that perfectly matched the Zodiac letters. The final confirmation came when Seda inadvertently signed his police statement with a symbol resembling a crosshairs, the exact signature used by the Zodiac. Herbert's sharp memory and attention to detail transformed a routine domestic violence arrest into the closure of a major serial killer investigation.
Following his success on the Zodiac task force, Herbert continued to serve the city with distinction. As detailed in his New York Times obituary, Herbert transitioned to the Joint Terrorism Task Force (JTTF). In the aftermath of the September 11 attacks, his expertise in complex, long-term investigations proved invaluable in securing the city against future threats. His passing in late 2025 marked the end of an era for the NYPD detectives who navigated the high-crime decades of the late 20th century.
Despite the massive resources poured into the Zodiac task force, the killer was not caught through traditional serial killer profiling. In fact, Seda defied many of the behavioral profiles generated by experts at the time. He was a young man living quietly with his mother in East New York, Brooklyn, and did not fit the expected mold of a highly organized, sophisticated criminal mastermind.
The breakthrough occurred on June 18, 1996, stemming from a violent family argument. Seda, who had become increasingly paranoid and aggressive, engaged in a heated dispute with his half-sister, Gladys "Chachi" Reyes. The argument escalated, and Seda drew a weapon, shooting Reyes in the buttocks as she attempted to flee their apartment.
Reyes managed to escape and alert the authorities, leading to a tense, hours-long standoff between Seda and the NYPD. Heavily armed police surrounded the building, unaware that the man barricaded inside was the notorious serial killer who had terrorized the city years earlier. Seda eventually surrendered peacefully. It was during the subsequent processing at the precinct that he wrote the confession that caught Detective Herbert's eye, as documented in historical summaries of the case.
Heriberto Seda was a self-proclaimed copycat. He was fascinated by the original Zodiac killer who operated in Northern California during the late 1960s and early 1970s. However, while Seda adopted the name and the concept of taunting the police, his methods, weaponry, and psychological motivations differed significantly from his predecessor.
| Criteria | San Francisco Zodiac (Original) | New York Zodiac (Heriberto Seda) |
|---|---|---|
| Years Active | Late 1960s – Early 1970s | 1990 – 1993 |
| Confirmed Victims | 5 fatalities, 2 injured | 3 fatalities, 6 injured |
| Signature/Taunts | Complex cryptograms, ciphers, crosshairs symbol | Maritime signal flags, astrological wheels, crosshairs symbol |
| Weaponry | Commercially available handguns, knives | Improvised, homemade "zip guns" |
| Victim Selection | Often couples in secluded areas, cab drivers | Targeted specific astrological signs, attacked on 21-day intervals |
| Current Status | Unidentified, case remains open | Captured, serving 232 years in NY State prison |
The psychology of the copycat is complex. Seda sought the infamy associated with the Zodiac name, but he adapted the methodology to fit his own delusions. His strict adherence to a 21-day interval between his early attacks created a predictable cycle of fear in New York City, a pattern that the original California killer did not employ.
One of the most fascinating, yet rarely discussed, aspects of the NYPD's hunt for Seda was the sheer desperation that led investigators to consult unconventional experts. Because Seda was selecting victims based on their astrological signs and leaving behind complex codes, traditional police work was hitting dead ends.
In an effort to anticipate the killer's next move, the NYPD task force reached out to an astronomer to track celestial movements, an astrologist to interpret the killer's star-chart logic, and even a self-proclaimed warlock. This warlock introduced detectives to the occult writings of Aleister Crowley, theorizing that the killer might be drawing inspiration from early 20th-century mysticism.
Seda's letters were visually striking, often featuring a sequence of symbols that baffled initial investigators. The breakthrough in decoding these messages came from outside the police department. Kieran Crowley, a journalist for the New York Post, recognized that the symbols were not occult runes, but rather International Maritime Signal Flags.
Crowley enlisted the help of his father-in-law, a veteran of World War II signals intelligence, to translate the flags. The decoded messages revealed taunts directed at the police and clues about the astrological signs of his intended victims. This collaboration between the press and military intelligence veterans highlights the highly unusual nature of the investigation.
A major reason Seda evaded capture for over three years was his choice of weaponry. He did not use standard, commercially manufactured firearms. Instead, he engineered his own weapons, commonly known as "zip guns."
Seda's reliance on zip guns almost led to his downfall years before his official capture, but a legal loophole saved him. In 1994, Seda was arrested for possessing one of his homemade weapons. However, when the police laboratory tested the device, it failed to fire properly during their examination. Because the weapon was deemed "non-functional" under the legal definitions of the time, the serious weapons charges were dropped, and Seda was released.
According to psychological assessments later discussed in court, this near-miss had a profound impact on Seda. He interpreted his release as a sign of divine intervention, fueling a delusion of invincibility that emboldened him to continue his criminal activities.
Since his conviction, Seda has been housed in New York's maximum-security prison system. Over the years, his location has shifted between facilities—a common practice in the Department of Corrections to manage security, population levels, and inmate safety. While early reports placed him at Attica, other records have linked him to the Clinton Correctional Facility in Dannemora.
Prison life for Seda has occasionally made headlines. In 2004, a detailed report emerged regarding Seda's personal life behind bars. He had entered into a romantic relationship with a fellow inmate, Synthia-China Blast, a transgender woman serving time for a gang-related homicide.
The relationship garnered significant media attention, highlighting the complex social dynamics within maximum-security facilities. During interviews conducted around this time, Seda made a surprising admission: despite using astrology as the defining signature of his murder spree, he confessed that he actually knew very little about the subject. The astrological angle was merely a theatrical device used to generate fear and emulate the California killer, rather than a deeply held personal belief system.
While the mechanics of the investigation and the psychology of the killer often dominate the narrative, it is crucial to remember the human cost of Seda's actions. His spree left three people dead and six others with life-altering injuries.
The fatalities included Joseph Proce, an elderly man shot in the back; Patricia Fonti, who was stabbed repeatedly after Seda's zip gun failed to fire a lethal shot; and John Diacone, who was shot at close range. These individuals were targeted randomly, their only connection to the killer being their astrological signs, which Seda often guessed or deduced based on brief interactions.
The survivors of the attacks endured immense physical and psychological trauma. Mario Orozco, the first victim, survived a gunshot wound to the back but faced a long road to recovery. Jermaine Montenesdro was similarly ambushed and survived his injuries. The resilience of these survivors stands in stark contrast to the cowardice of the attacks. During the height of the spree, the knowledge that an untraceable sniper was operating on a strict 21-day schedule paralyzed many New York neighborhoods, fundamentally altering the daily routines of thousands of residents.
The intricate details of the New York Zodiac case continue to captivate audiences, leading to numerous media adaptations and deep-dive analyses. For those looking to explore the case further, several highly regarded productions offer extensive coverage.
Yes. As of 2026, Heriberto Seda is 58 years old and remains alive. He is currently incarcerated in a maximum-security prison in New York State, serving a 232-year sentence.
Seda was primarily motivated by a desire for infamy and a compulsion to copycat the original San Francisco Zodiac killer. He harbored delusions of grandeur and believed that carrying out these attacks would make him a feared and powerful figure, though he later admitted his interest in astrology was mostly superficial.
Heriberto Seda killed three people (Joseph Proce, Patricia Fonti, and John Diacone) and wounded six others during his crime spree between 1990 and 1993.
A zip gun is an improvised, homemade firearm constructed from common hardware materials. Because they lack the rifled barrels found in manufactured firearms, they do not leave identifiable ballistic striations on bullets, making them incredibly difficult for forensic investigators to trace.
No. There is no evidence that Heriberto Seda ever met or communicated with the original California Zodiac killer. The original Zodiac operated decades earlier and his identity remains unknown to this day. Seda simply read about the case and decided to adopt the persona.
Due to the consecutive nature of his sentencing for multiple murders and attempted murders, Seda's official parole eligibility date is set for the year 2231. This ensures he will never be released from prison.
The case of the New York Zodiac remains a landmark investigation in the history of the NYPD. It highlights the limitations of early 90s forensic technology against improvised weaponry, and the unpredictable nature of criminal profiling. As we look at the status of the case in 2026, several key facts stand out:
