Authorities have disclosed serious injuries and an alleged list of targets but little about how investigators linked Mahogany Massey to the fire.
DURHAM, N.C. — Investigators called the University Ridge apartment fire arson and arrested Mahogany Ashley Massey soon afterward, but the evidence showing where the flames started and how authorities connected her to them has not been made public.
The unanswered questions sit at the center of a seven-count felony case arising from a fire that injured residents and firefighters, displaced 18 people and left an entire apartment building uninhabitable. Prosecutors have emphasized a document they described as a “people to kill list,” an alleged earlier attempt to start a fire and injuries suffered by Massey’s mother and brother. The defense has called for mental health treatment. None of the prosecution’s allegations has been proved at trial.
Massey, 31, is charged with first-degree arson, three counts of arson resulting in serious injury to a firefighter and three counts of assault inflicting serious bodily injury. Court records cited by local media indicate that the arson-related charges were filed through the North Carolina Department of Insurance’s criminal investigations operation. That agency investigates suspected insurance fraud and certain fire-related crimes, often working with local fire and law enforcement officials.
The Durham Fire Department received the call at about 10:53 a.m. Sunday. Crews arrived within minutes and encountered heavy flames at the University Drive complex. Fire moved through the structure and emerged from the roof. Firefighters rescued one person through a first-floor window, while other occupants escaped on their own. One resident jumped from a third-floor window. Crews controlled the fire in about an hour.
Early reports said seven people were injured and five were taken to hospitals. Court documents and hearing accounts identified three firefighters, Massey’s mother and Massey’s brother among those hurt. The public reports did not fully reconcile how each injured person was counted, and officials did not release a final list naming the victims or detailing every injury.
Prosecutors said Massey’s mother suffered severe smoke inhalation and remained hospitalized. They said Massey’s brother entered the burning building to rescue her. Glass broke in the heat and cut an artery in his arm, causing blood loss that nearly killed him, according to the courtroom account. Three firefighters were seriously injured, the charges allege, but their conditions were not disclosed in detail.
Those consequences help explain the number and seriousness of the charges, but they do not answer the factual questions that prosecutors must prove. A first-degree arson case generally requires evidence that an occupied dwelling was deliberately and maliciously burned. The injury-based counts require proof connecting the alleged criminal act to the harm described in each charge. Massey’s identity as the person who started the fire remains a contested allegation.
News reports say authorities quickly determined that the fire was arson. They have not publicly described the burn patterns, laboratory testing, witness interviews or other findings behind that conclusion. No report reviewed for this article identified an accelerant or ignition device. Officials also have not said whether video from the apartment complex, nearby businesses or traffic cameras captured Massey’s movements.
Investigators often limit what they release during an active case to protect evidence and avoid influencing witnesses. That practice can leave early public accounts dependent on charging language and courtroom summaries. Defense attorneys later receive discoverable evidence through the court process and can seek to exclude material they believe was improperly obtained, unreliable or irrelevant.
The alleged list is one example of evidence that may require extensive examination. Prosecutors said investigators found a “people to kill list” among Massey’s belongings. The list itself has not been released. The available reports do not identify who was named, when the writing was created, what words appeared around the names or whether it referred specifically to the apartment fire.
Without those details, it is not possible to determine the list’s full meaning or legal value. Prosecutors could argue that it shows planning, intent or motive. The defense could dispute authorship, context or whether the document had any connection to the charged conduct. A court may also have to consider how investigators obtained it and whether the search complied with legal requirements.
Prosecutors added that Massey had tried to start a fire at University Ridge about a week earlier. That assertion has not been supported publicly with a separate fire report or criminal charge. WRAL said it asked the Fire Department for confirmation and had not received a response at the time of its report. Officials did not describe the location, method or outcome of the alleged attempt.
The building itself will likely be part of the physical investigation. University Ridge was built in the 1980s, according to property records cited by WRAL. It contained 18 units, nine of which were occupied when the fire occurred. Officials said every unit was left unlivable, including apartments that may not have sustained direct flame damage but were affected by smoke, water or structural concerns.
The structure did not have an automatic sprinkler system. North Carolina’s requirements for sprinklers in apartment buildings were adopted after the complex was constructed, according to local reporting. The Fire Department did not publicly accuse the property owner of violating building rules, and no source reviewed for this article said the system was legally required when University Ridge was built.
The lack of sprinklers is therefore a contextual fact rather than proof of fault. Investigators would need to examine the building’s construction, fire barriers, alarms, exits and maintenance records before drawing conclusions about how flames traveled. No engineering report or inspection history analyzing those points was available in the reviewed coverage.
Resident Justice Houllier’s account provides a limited view of the warning system. He said an alarm began sounding in the apartment below him before his own alarm activated. After seeing fire and concluding that he could not leave safely through the building, he climbed from a third-story window. Houllier suffered a fractured spine and a serious foot injury when he landed.
His experience may help investigators reconstruct the fire’s movement and timing. The order in which alarms sounded could indicate where smoke traveled first, although a single resident’s recollection cannot establish the point of origin. Investigators would also consider alarm placement, device records, witness locations and physical damage before reaching a final conclusion.
Another part of the case concerns Massey’s conduct and condition. Her father, Daron Massey, told ABC11 that she remained near the scene as her mother was moved to an ambulance. He said his daughter sat on a wall, smoked a cigarette and drank a beer. He also said she had stopped taking psychiatric medication about two months earlier and had a history of severe mental illness.
The father’s observations may become evidence, but their purpose would have to be established. Remaining at a scene can allow investigators to locate and question a suspect, yet unusual behavior is not a substitute for proof that the person started a fire. Statements about Massey’s health are also family testimony rather than independent medical findings.
Massey’s defense lawyer reportedly urged the court to place her in treatment rather than jail. Reports said she interrupted her first appearance several times, and the judge continued without her present. The judge ruled that Massey posed a danger to the community and ordered her held without bond. That ruling addressed pretrial custody, not whether she committed the offenses.
The record available to the public does not show whether a competency evaluation was ordered. Should competency become an issue, clinicians and the court would examine whether Massey can understand the proceedings and assist her lawyer. That question is distinct from whether a mental condition affected her conduct when the fire was set. Neither issue can be resolved solely through interviews with relatives. The displaced residents face a more immediate uncertainty. Officials have not announced when any part of the building could reopen or whether it will be repaired. Residents may have lost clothing, furniture, documents and other property, while some also face medical recovery. The reviewed reports did not provide a complete estimate of property damage or identify the complex’s insurance arrangements.
For firefighters, a formal review may address tactics, protective equipment and the circumstances that led to three reported injuries. Such reviews can occur separately from a criminal investigation. No department report detailing the injuries or evaluating the response had been released publicly when the sources for this article were reviewed.
The case will ultimately depend on evidence rather than the dramatic details that dominated its first headlines. Prosecutors must establish the fire’s origin, Massey’s identity as the person responsible, the required intent and the connection between the alleged act and each injury. The defense can contest each link and seek expert review of the fire investigation and Massey’s mental condition.
Public sources did not establish what occurred at any later hearing or whether the charges had been modified. Massey is being held in custody without bond at the latest point confirmed by the available reporting. Until more records are released, the list, the alleged earlier attempt and the cause-and-origin findings remain prosecution claims awaiting examination in court.
