A devastating four-alarm fire in Jersey City has claimed the life of 90-year-old Zenaida Mojica, injured three other people and forced 19 residents from their homes.
Mojica was identified Friday, October 2, 2026, as the woman who died after flames tore through a residence at 81 Boyd Avenue on Jersey City’s West Side the previous evening.
Firefighters removed Mojica from the burning home during suppression efforts, but she was pronounced dead a short time later.
The Hudson County Regional Arson Task Force and Jersey City Fire Department are investigating the cause and origin of the blaze. Authorities have said foul play is not suspected.
What Happened on Boyd Avenue?
The Jersey City Fire Department was called to the Boyd Avenue property shortly after 5:10 p.m. on Thursday, October 1.
Firefighters arrived to find heavy flames coming from the home.
The emergency quickly developed into a major response as crews worked to control the fire and prevent it from spreading farther through the densely built residential neighborhood.
During the firefighting operation, responders located Zenaida Mojica inside the property.
She was removed from the residence but could not be saved.
Two male residents and one firefighter were also injured. Authorities said their injuries were not considered life-threatening.
The fire ultimately displaced 19 people from nearby residences.
Firefighters Faced Difficult Conditions
Fire crews encountered challenging conditions while attempting to reach people inside the burning property.
Local reports described intense flames coming from the upper portion of the building as firefighters worked their way through the residence.
Firefighters also encountered debris that made portions of the home difficult to access.
Crews had to move through dangerous conditions while simultaneously searching for occupants and working to contain the flames.
The response escalated to four alarms as additional firefighters and equipment were called to Boyd Avenue.
The fire also threatened adjoining properties because of the close spacing of homes in the neighborhood.
Firefighters opened portions of the roof as part of efforts to contain the spread.
Who Was Zenaida Mojica?
Authorities identified the woman killed in the fire as Zenaida Mojica, 90, of Jersey City.
Public information released immediately after the fire has focused primarily on the emergency response and investigation.
Detailed biographical information about Mojica has not yet been widely released by her family.
For that reason, personal details about her life, occupation, family relationships or history should not be assumed.
What authorities have confirmed is that Mojica was inside the Boyd Avenue residence when the fire occurred and was removed by firefighters during their response.
Her death has turned what was initially reported as a major residential fire into a fatal incident now under formal investigation.
What Authorities Have Said
Hudson County Prosecutor Wayne Mello confirmed Mojica’s identity after the fire.
Authorities said firefighters were dispatched to 81 Boyd Avenue shortly after 5:10 p.m. and encountered heavy fire upon arrival.
Mojica was removed during firefighting operations and pronounced dead shortly afterward.
Officials also confirmed that two men who lived at the property and one firefighter suffered injuries that were not believed to be life-threatening.
The Hudson County Regional Arson Task Force is working with Jersey City fire officials to determine where and how the blaze began.
Authorities have specifically stated that foul play is not suspected at this stage of the investigation.
Jersey City Mayor Responds to the Tragedy
Jersey City Mayor James Solomon acknowledged the fatal fire while crews were still dealing with its aftermath.
The mayor said the fire department had brought the four-alarm blaze under control and confirmed that residents had been transported for medical treatment.
He also expressed sympathy for the victim’s family and said the city was prepared to provide assistance to those affected.
The city’s response has extended beyond the immediate firefighting operation because numerous people were left unable to return to their homes.
Nineteen People Displaced
The fire affected more than the household where it began.
Officials said 19 residents were displaced as a result of the blaze.
Some nearby homes were impacted by the fire or by emergency operations required to stop the flames from spreading.
The American Red Cross was reported to be helping affected residents following the emergency.
For families suddenly displaced by a residential fire, immediate concerns can include temporary accommodation, medication, clothing, important documents and determining whether their homes are safe to enter.
Officials are expected to continue assessing the affected properties.
What Has Been Confirmed
Zenaida Mojica was 90 years old and lived in Jersey City.
The fatal fire occurred on Thursday, October 1, 2026.
Firefighters responded to 81 Boyd Avenue shortly after 5:10 p.m.
Mojica was removed from the home during firefighting operations.
She was pronounced dead shortly afterward.
Two male residents and one firefighter suffered injuries described as non-life-threatening.
Nineteen residents were displaced.
The fire escalated to a four-alarm response.
The Hudson County Regional Arson Task Force and Jersey City Fire Department are investigating the cause and origin.
Authorities have said foul play is not suspected.
What Has Not Been Confirmed
Authorities have not publicly announced what started the Boyd Avenue fire.
The exact point of origin inside the property has not been publicly established.
Investigators have not announced whether an electrical problem, cooking incident, heating equipment or another source caused the blaze.
No official finding regarding the cause should therefore be assumed.
Authorities have also not released extensive personal information about Zenaida Mojica.
Funeral, memorial or visitation arrangements had not been broadly announced in the initial verified reporting following her identification.
Any fundraising campaigns or social-media accounts claiming to represent Mojica’s family should be independently verified before donations are made.
Why the Boyd Avenue Fire Matters
Residential fires can unfold within minutes, particularly in neighborhoods where homes are positioned close to one another.
The Boyd Avenue fire required a large emergency response and affected numerous households beyond the immediate property.
The death of a 90-year-old resident also highlights the particular danger fires can pose to older adults who may have difficulty moving quickly during an emergency.
Fire investigations following fatal incidents are intended to determine not only where a blaze began but whether there are lessons that could help prevent similar tragedies.
The final findings in this case could therefore be important for both Mojica’s family and the wider Jersey City community.
Investigation Into the Cause Continues
Investigators from the Hudson County Regional Arson Task Force are expected to examine the damaged property as they work to determine the origin and cause of the fire.
That process may include examining electrical systems, appliances, heating equipment and burn patterns inside the building.
Investigators may also interview survivors, neighbors and firefighters who were among the first people at the scene.
The involvement of an arson task force does not mean investigators believe the fire was intentionally set.
Such specialized units routinely investigate serious and fatal fires to determine their cause.
Authorities have already said foul play is not suspected.
Community Faces the Aftermath
For those who lived along Boyd Avenue, the consequences of the fire extend beyond Thursday evening.
Several households now face displacement while officials determine whether damaged homes can safely be occupied.
Residents may also have lost possessions and other personal belongings during the fire.
At the center of the tragedy is the loss of Zenaida Mojica.
As investigators continue their work, her relatives and those who knew her are left mourning a life lost during an emergency that unfolded rapidly in their neighborhood.
What Happens Next
The Hudson County Regional Arson Task Force and Jersey City Fire Department will continue investigating the fire’s origin and cause.
Officials may release additional findings after investigators complete their examination of the property.
Authorities could also provide further information about the displaced families and the condition of the injured residents and firefighter.
Mojica’s family may separately announce funeral or memorial arrangements.
Until additional information becomes available, claims about exactly what started the fire should be treated as unconfirmed.
