$25,000 Reward Offered as Search for Margaret Haddican-McEnroe Approaches Two Decades
New Jersey Mother Disappeared From Her Warren Township Home in October 2006
Margaret Haddican-McEnroe disappeared from her residence in Warren Township, New Jersey, on October 10, 2006, beginning a mystery that has remained unresolved for nearly two decades. The FBI is offering a reward of up to $25,000 for information leading to the arrest and conviction of anyone involved in her disappearance. Haddican-McEnroe has not been located, and authorities continue to seek information capable of establishing what happened to her after she was last seen.
At the time she disappeared, Haddican-McEnroe was 29 years old and a mother of three. She was also pregnant when she vanished, making the circumstances of her disappearance particularly concerning. Her case remains an active missing-person investigation involving the Warren Township Police Department, Somerset County Prosecutor's Office, New Jersey State Police, and FBI.
Last Seen at Her Warren Township Residence
Haddican-McEnroe was last seen at her home in Warren Township on October 10, 2006. That residence became the starting point for investigators attempting to reconstruct her final known movements. Authorities have continued searching for information from anyone who saw her, communicated with her, or had knowledge of her activities around the time she vanished.
Establishing a reliable timeline is critical in a long-term missing-person investigation. Investigators must determine not only the last confirmed sighting but also telephone communications, transportation, financial activity, personal relationships, and anything unusual that occurred immediately before the disappearance. Even after many years, previously unreported information can potentially change investigators' understanding of a case.
What Margaret Was Wearing
Authorities have released a detailed description of the clothing Haddican-McEnroe was believed to be wearing when she disappeared. She was last seen wearing a black BDU-style jacket, a gray Army sweatshirt with black lettering, white checkered pajama pants, white socks, and white Nike sneakers. The unusual combination of clothing could help someone remember encountering her on or around October 10, 2006.
Haddican-McEnroe was also wearing distinctive jewelry, including a silver chain with dog tags and a white wedding ring containing three diamonds. Investigators believe she may have been carrying a black bag containing additional clothing. These details remain important because clothing, jewelry, or personal possessions could potentially help identify evidence discovered years after the original disappearance.
Also Known as Sherwood Haley
Haddican-McEnroe also uses the birth name Sherwood Haley. Alternative names can be particularly important in long-running missing-person investigations because records, acquaintances, employment histories, medical information, or other documents may exist under different names.
Someone who knew her earlier in life may recognize Sherwood Haley but not immediately recognize the name Margaret Haddican-McEnroe. Publishing both names expands the possibility that former friends, coworkers, neighbors, or acquaintances could recognize her and provide information.
Investigators examining historical records must similarly account for name changes. Records connected to addresses, employment, education, relationships, or other activities can sometimes appear under a birth name rather than a married name.
Pregnant When She Disappeared
One of the most significant circumstances surrounding Haddican-McEnroe's disappearance is that she was pregnant at the time. She was approximately five months pregnant when she vanished, according to information released in connection with the investigation.
Her pregnancy added immediate urgency to the search because investigators were effectively concerned about the safety of both Haddican-McEnroe and her unborn child. A pregnant woman disappearing without a confirmed explanation naturally raised serious questions about whether she had voluntarily left or whether something had happened to her.
The passage of time has only intensified those questions. There has been no publicly confirmed resolution explaining where Haddican-McEnroe went after October 10, 2006, or what happened to her pregnancy.
Mother of Three Children
Haddican-McEnroe was already the mother of three children when she disappeared. Her responsibilities and family circumstances became an important part of the investigation into whether she would have intentionally vanished without maintaining contact.
When examining a disappearance, investigators typically consider a person's relationships, responsibilities, routines, plans, and previous behavior. Leaving behind children and family can become an important factor when determining whether a disappearance is consistent with someone's established behavior.
Authorities have continued treating Haddican-McEnroe's case as unresolved rather than concluding that she voluntarily disappeared. The FBI's decision to offer a reward specifically for information leading to the arrest and conviction of those involved indicates that investigators continue to consider the possibility that another person was responsible.
A Case With Possible Criminal Involvement
The wording of the FBI's $25,000 reward is significant. Rather than simply offering money for information locating Haddican-McEnroe, the FBI is offering the reward for information leading to the arrest and conviction of those involved in her disappearance.
That language reflects the criminal-investigative dimension of the case. Authorities are not merely attempting to determine where a missing adult chose to go; they are seeking information that could identify people responsible for her disappearance.
Investigators have not publicly disclosed every piece of evidence collected during the case. Maintaining confidentiality around certain details can help authorities evaluate tips, protect witnesses, and distinguish information genuinely connected to the disappearance from speculation.
The First Hours and Days of the Investigation
The period immediately following a disappearance is often critical. Investigators attempt to determine when the missing person was last reliably seen, who had contact with them, whether they had transportation, and whether their personal belongings suggest they intended to leave.
In Haddican-McEnroe's case, the detailed clothing description and possibility that she carried a black bag provide clues about her appearance at the time she vanished. Investigators have also had to consider whether the additional clothing in the bag indicated travel plans or had another explanation.
No single detail should be interpreted independently as proof of what occurred. Investigators build missing-person cases by comparing multiple pieces of evidence and determining which explanations remain consistent with the complete record.
Nearly Twenty Years Without Answers
October 2026 will mark 20 years since Haddican-McEnroe disappeared. The extraordinary passage of time creates major investigative challenges because memories fade, witnesses relocate, relationships change, and physical evidence can become increasingly difficult to locate.
At the same time, old cases can be solved years or even decades later. Advances in forensic science, digital databases, DNA analysis, genealogical research, and information sharing have provided investigators with methods that were not as widely available when many older cases began.
Relationships can also change over time. Someone who was unwilling to speak in 2006 may no longer feel the same loyalty or fear that prevented them from contacting investigators. A person who heard something secondhand may only later understand its potential importance.
Why Previously Unreported Information Still Matters
Investigators do not necessarily need a witness who knows exactly what happened to Haddican-McEnroe. A smaller piece of information could potentially corroborate or contradict an existing theory. A remembered conversation, vehicle, visitor, telephone call, unusual statement, or sighting could help investigators strengthen the timeline surrounding October 10, 2006.
People sometimes fail to report information because they assume authorities already know it. Others may believe a detail is too insignificant or that too much time has passed for it to matter. In a long-term missing-person investigation, those assumptions can prevent investigators from receiving information that could be valuable when combined with evidence already in the case.
Anyone who knew Haddican-McEnroe around the time of her disappearance should consider whether there is information they never shared with investigators. Authorities, rather than witnesses themselves, can determine whether that information has investigative value.
Distinctive Jewelry Could Remain Important
The silver chain with dog tags and the white three-diamond wedding ring Haddican-McEnroe was wearing are especially important identifying details. Unlike clothing, jewelry can survive for decades and may remain recognizable long after a disappearance.
Personal jewelry can also carry emotional significance, making it something a person wears consistently. Investigators documenting these items preserve information that could potentially assist with identification if property or unidentified remains are discovered at a later date.
The dog tags may be particularly distinctive depending on what information or markings they contained. Authorities have included the necklace and wedding ring in descriptions of Haddican-McEnroe's appearance when she vanished.
The Black Bag
Investigators believe Haddican-McEnroe may have been carrying a black bag containing additional clothing. That detail raises questions about whether she expected to be away from home, although the presence of extra clothing alone cannot establish her intentions.
Determining what was inside the bag and whether anything else was missing from the residence could potentially help establish whether Haddican-McEnroe prepared to leave or whether the bag had an unrelated purpose. Investigators would also consider whether identification, money, medication, personal documents, or other important belongings disappeared with her.
In missing-person investigations, what remains behind can sometimes be as important as what disappears. Personal belongings can help authorities assess whether someone's departure appears planned or inconsistent with their normal behavior.
Multiple Agencies Involved
The investigation has involved local, county, state, and federal authorities. Warren Township Police have remained connected to the case, while the Somerset County Prosecutor's Office and New Jersey State Police have also participated in efforts to determine what happened.
The FBI's involvement provides additional federal investigative resources and allows the case to receive national exposure through its missing-person listings. That broader publicity is particularly valuable after many years because potential witnesses may no longer live in New Jersey.
A person with relevant information could now be anywhere in the United States or overseas. Keeping Haddican-McEnroe's photograph, identifying information, and case details publicly accessible increases the possibility that someone will recognize the case and come forward.
$25,000 Reward for Information
The FBI is offering up to $25,000 for information leading to the arrest and conviction of those involved in Haddican-McEnroe's disappearance. The reward remains an important incentive for anyone possessing information that could identify a person responsible for what happened.
A useful tip does not necessarily have to independently solve the entire case. Information identifying a previously unknown witness, location, vehicle, conversation, or relationship could potentially provide investigators with a new direction.
The reward also sends an important message about the status of the investigation. Nearly two decades after Haddican-McEnroe vanished, federal authorities are still seeking information and have not closed the door on identifying and prosecuting anyone responsible.
Margaret Haddican-McEnroe Remains Missing
Margaret Haddican-McEnroe has remained missing since October 10, 2006, when she was last seen at her residence in Warren Township, New Jersey. She was 29 years old, approximately five months pregnant, and the mother of three children when she disappeared. She was wearing a black BDU jacket, gray Army sweatshirt, white checkered pajama pants, white socks, white Nike sneakers, a silver chain with dog tags, and a white wedding ring containing three diamonds.
Nearly 20 years later, the central question remains unanswered: what happened to Margaret Haddican-McEnroe after she was last seen at home? The FBI is offering up to $25,000 for information leading to the arrest and conviction of anyone involved in her disappearance. Anyone with information should provide it directly to appropriate law-enforcement authorities rather than attempting to independently investigate people potentially connected with the case.
