A California couple has been convicted of murder after their 19-month-old daughter died from fatal fentanyl poisoning in a shocking case that has highlighted the ongoing opioid crisis in the United States.

Derek Rayo and Kelly Richardson were found guilty after prosecutors proved that their toddler, Winter Rayo, died in August 2023 after being exposed to a deadly combination of fentanyl and methamphetamine inside their home in San Jose.

According to court testimony and reports from investigators, the child was left in a room where illegal narcotics were present. Authorities said the parents waited approximately 11 hours before calling emergency services, telling dispatchers they were unaware of what had happened.

By the time first responders arrived, the child had already been dead for several hours.

An autopsy revealed the severity of the overdose, confirming that Winter Rayo had more than 25 times the lethal amount of fentanyl in her system. Medical findings also showed that the child had ingested the drug, with traces of undigested fentanyl discovered in her stomach.

Santa Clara County District Attorney Jeff Rosen described the circumstances as a devastating act of criminal negligence and recklessness, stating that fentanyl was left accessible “like a loaded gun” in a home where a toddler was present.

During the trial, prosecutors argued that both parents were fully aware of the dangers associated with fentanyl exposure. Evidence presented in court indicated that Rayo had previously worked as a drug and alcohol counselor and had personal connections to overdose victims, making the presence of narcotics in the home even more concerning.

Investigators also revealed disturbing details about the living conditions in the household. Drug use reportedly occurred inside the home, including sessions involving a drug dealer identified as Philip Ortega, who at one point lived with the family. Prosecutors alleged that during these drug sessions, the child was sometimes physically restricted in unsafe ways while adults used narcotics nearby.

Photographs presented in court reportedly showed drugs and paraphernalia within easy reach of the toddler, reinforcing claims that the environment was extremely hazardous.

Ortega himself has also faced legal consequences, with prosecutors charging him in connection with multiple child deaths, including another infant case referenced in court proceedings.

On May 8, the jury found both Rayo and Richardson guilty of second-degree murder. Sentencing is pending, and both defendants face potential prison terms of 15 years to life.

District Attorney Rosen praised the jury’s verdict, stating that the decision acknowledged the severity of the child’s death and the responsibility of those involved.

The case adds to a growing number of tragedies linked to fentanyl exposure in the United States, where accidental ingestion or environmental contact with the drug has become a leading cause of child overdose deaths in recent years.

Authorities continue to warn that even extremely small amounts of fentanyl can be lethal, particularly to young children, and emphasize the importance of safe storage and strict control of all narcotics.

The sentencing date for Rayo and Richardson has not yet been scheduled.
