The sentencing of a New York City daycare owner and her husband has closed one of the most disturbing criminal cases involving childcare in recent years. Authorities revealed that what appeared to be a normal daycare center in the Bronx was secretly used as a hub for processing and storing large quantities of fentanyl, one of the most powerful and dangerous synthetic opioids. The case gained widespread attention after the death of a 22-month-old toddler who had been placed in the facility under the expectation of safety and care.
Instead, prosecutors described a situation where children were unknowingly exposed to toxic narcotics stored and handled inside the building where they played, ate, and slept. A state court jury found Grei Mendez and her husband, Felix Herrera Garcia, guilty of second-degree murder and assault in connection with the fatal poisoning of Nicholas Dominici. The verdict reflected the gravity of the actions described during the trial, where prosecutors argued that the defendants knowingly allowed fentanyl to be stored and processed in a space meant for young children.
In March, the couple received sentences of 25 years to life in prison for the state murder conviction. The punishment will run concurrently with an earlier federal sentence of 45 years they received after pleading guilty to related drug trafficking charges.
The case drew national attention because of the shocking details that emerged during the investigation. Officials said narcotics were not only present inside the daycare facility but were allegedly handled using the same kitchen tools used to prepare food for the children. Investigators discovered that the building contained significant quantities of fentanyl hidden in areas close to where toddlers spent their time. These revelations led prosecutors to argue that the daycare operation had effectively become a front that shielded a large-scale drug enterprise, placing children at extraordinary risk.
A Tragic Day Inside the Bronx Daycare
The events that led to Nicholas Dominici’s death unfolded in September 2023 at the Divino Niño daycare center in the Bronx. On that day, several toddlers who had been left at the facility by their families began to show signs of serious medical distress. According to authorities, the children suddenly became unresponsive and displayed symptoms consistent with opioid poisoning. Emergency responders were called after the situation became critical, but by the time help arrived the effects of the exposure had already caused severe harm.
Four children were affected by the fentanyl exposure that day. Nicholas Dominici, who was only 22 months old, was among them. Despite efforts by medical personnel, he died after being taken to a hospital. Three other children survived but suffered serious medical emergencies that required urgent treatment. A two-year-old boy named Abel Garcia reportedly went into respiratory arrest, a life-threatening condition in which breathing stops or becomes severely compromised. Doctors were able to revive him at the hospital, preventing another fatality.
Two additional children were also hospitalized following the incident. Abel’s eight-month-old sister, Kiara Garcia, and another two-year-old child, Jaziel Lino, were treated for acute opioid intoxication. Medical professionals determined that their symptoms were caused by exposure to fentanyl inside the daycare facility. While both children ultimately survived, the situation highlighted the extraordinary danger posed by the presence of even tiny amounts of the drug in environments where young children are present.
Fentanyl is an extremely potent synthetic opioid that can be deadly in very small doses. Exposure can occur through ingestion, inhalation, or contact with contaminated surfaces. In environments where the drug is handled or processed, microscopic particles can spread easily and create life-threatening risks. Prosecutors argued during the trial that storing and processing such a substance in a daycare setting represented an extreme disregard for the safety of the children entrusted to the facility.

The investigation that followed the incident revealed troubling details about the conditions inside the daycare center. Authorities said that drugs had been concealed in various locations within the building. One kilogram of fentanyl was reportedly found in a closet, while investigators also discovered an additional stash hidden beneath a trapdoor located in the children’s playroom. In total, prosecutors said approximately 12 kilograms of narcotics were stored beneath the floor.

The presence of such large quantities of drugs inside a childcare facility stunned investigators and prosecutors alike. According to court filings, the narcotics were stored only steps away from areas where toddlers slept, played, and participated in daily activities. The proximity between the drugs and the children was cited as one of the most disturbing elements of the case.
The Investigation and Evidence Uncovered
After the children were found sick, law enforcement agencies launched an intensive investigation to determine how the poisoning had occurred. Detectives examined the daycare facility and began tracing the movements of those responsible for operating the center. Evidence collected at the scene quickly suggested that the poisoning was linked to a much larger narcotics operation being run out of the building.
Prosecutors told the court that fentanyl was not simply stored at the daycare but was actively processed there. Investigators determined that tools from the daycare kitchen had allegedly been used for drug preparation as well as food preparation. This detail became a central element of the prosecution’s argument that the defendants had created an environment where children were exposed to extremely dangerous substances without their parents’ knowledge.
Authorities also examined the actions taken by the defendants after the children began to show symptoms of poisoning. According to prosecutors, Grei Mendez did not immediately call emergency services when she realized the toddlers were in distress. Instead, she first contacted her husband, Felix Herrera Garcia. Investigators believe this call gave Garcia time to return to the building and remove drugs from the scene.

Garcia allegedly fled the daycare with plastic bags filled with narcotics after being alerted by his wife. Prosecutors said the bags were weighted down, suggesting they contained significant quantities of drugs. Surveillance footage and other evidence helped investigators piece together the timeline of events that followed the children’s collapse.
Following the incident, Garcia left the United States and traveled to Mexico. Law enforcement agencies tracked his movements and eventually located him there. He was later arrested and extradited back to New York to face criminal charges in connection with the case. His flight from the country was presented in court as evidence that he knew the seriousness of the crime and attempted to avoid prosecution.
During the search of the daycare center, investigators uncovered additional evidence linking the couple to a broader drug trafficking operation. The narcotics found inside the building represented a substantial quantity of fentanyl, a drug frequently associated with fatal overdoses across the United States. Authorities concluded that the daycare facility had effectively been used as a storage and distribution point for illegal drugs.
Prosecutors argued that the defendants deliberately used the presence of children to shield their criminal activity from suspicion. Because daycare centers are generally perceived as safe environments for families, authorities said the building provided a convenient cover for the narcotics operation.
Court Proceedings and Sentencing
The legal proceedings that followed the investigation involved both federal and state criminal cases. In federal court, Grei Mendez and Felix Herrera Garcia pleaded guilty to drug trafficking charges connected to the narcotics operation discovered inside the daycare. The couple received a federal sentence of 45 years in prison for those offenses. The state case focused specifically on the death of Nicholas Dominici and the injuries suffered by the other children. Prosecutors pursued charges of second-degree murder and assault, arguing that the defendants’ actions directly led to the fatal poisoning.

After reviewing the evidence presented during the trial, the jury found both defendants guilty of those charges. In March, a New York judge sentenced the couple to 25 years to life in prison for the murder conviction. Because the federal sentence had already been imposed, the state sentence will run concurrently with the 45-year federal term. This means the couple will serve the sentences at the same time rather than consecutively, but the penalties together ensure they will remain incarcerated for decades.

During public statements about the case, prosecutors emphasized the betrayal of trust involved in operating a daycare facility while engaging in drug trafficking. The Bronx district attorney described the defendants’ actions as driven by greed and characterized the situation as a tragic example of how criminal activity can endanger innocent lives. Officials also highlighted the fact that the narcotics were hidden in the same space where children spent their days. According to prosecutors, toddlers at the daycare were unknowingly placed in direct proximity to extremely dangerous drugs.
This environment ultimately led to the poisoning that killed Nicholas Dominici and hospitalized three other children. In earlier court proceedings related to the federal charges, Grei Mendez expressed remorse for what had happened. She told the court that she initially believed her husband was helping her when they opened the daycare center. However, she later realized that the facility had become a convenient way to conceal his drug business.
Mendez said that the consequences of the tragedy would remain with her permanently. Her statement came as part of her guilty plea in the federal case, where she acknowledged her role in the operation that allowed narcotics to be stored and processed inside the daycare. The death of Nicholas Dominici has left a lasting impact on his family and on the community where the daycare operated. The case also prompted broader discussions about oversight of childcare facilities and the dangers posed by fentanyl, which has become a major factor in overdose deaths across the United States.
Investigators and prosecutors involved in the case described it as one of the most troubling situations they had encountered. The combination of childcare services and large-scale drug trafficking created a dangerous environment that ultimately resulted in the loss of a young life. The sentences handed down in court represent the legal system’s response to a tragedy that began inside what should have been a safe place for children.
