South Florida Man Sentenced to 30 Years in Prison for Distribution of Fentanyl Resulting in Death of Baby and Possession of Firearms as a Convicted Felon

MIAMI - Yesterday afternoon, Darnell Mendez, 36, was sentenced to 30 years in federal prison, followed by five years of supervised release, by U. S. District Judge Robin L. Rosenberg. Mendez and his girlfriend, Samantha Yi, previously pled guilty to federal offenses resulting from a long-term joint investigation by the Boynton Beach Police Department (BBPD), the Palm Beach County Sheriff's Office (PBSO), and the Drug Enforcement Administration (DEA) following the death of a 10-month-old infant in Boynton Beach, Fla. who had ingested fentanyl. Yi is scheduled to be sentenced on Jan. 9, 2025, and faces a minimum mandatory sentence of at least twenty years in prison.

On March 31, 2022, PBSO responded to a 911 call of an infant in distress. The infant was transported to Bethesda Hospital East in Boynton Beach with her mother. On April 1, 2022, the baby was transferred to Joe DiMaggio Children's Hospital in Hollywood, Fla. On April 5, 2022, the baby died. An autopsy conducted by the Palm Beach County Medical Examiner determined that the baby's death was caused by fentanyl intoxication and that her manner of death was a homicide.

The BBPD conducted a homicide investigation during which law enforcement recovered fentanyl at the baby's home. The investigation determined that the baby's mother and father were addicts and had been abusing fentanyl regularly in the kitchen of their apartment. The investigation also determined that the baby was teething and ingested fentanyl on March 31, 2022, while in the care of her mother, and while her father was at work. The mother was arrested by the BBPD and charged with aggravated manslaughter of a child by culpable negligence.

DEA joined the investigation to identify the drug dealers that were responsible for the distribution of the fentanyl that killed the baby. Through data and information retrieved from the mother's cellphone, law enforcement was able to identify Yi as the drug dealer. The investigation uncovered months of electronic communications exchanged between Yi and the mother involving drug transactions in which the mother was the customer. The investigation further determined that Yi's boyfriend, Mendez was also involved in the distribution of fentanyl. Investigators were able to determine that on March 30, 2022, the mother met with Yi in Boynton Beach to purchase fentanyl, and that fentanyl was ingested by the baby resulting in her death.

As part of the joint investigation, DEA, the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), BBPD, and PBSO conducted an operation involving two undercover officers who purchased fentanyl from Yi and Mendez. The undercover operation culminated in the arrests of Yi and Mendez on March 6, at their residence in Lake Worth, where law enforcement discovered 14 firearms. As part of their pleas, Yi and Mendez admitted being felons unlawfully in possession of firearms.

Robinson of the ATF, Miami Field Division, Chief Joe DeGiulio of BBPD, and Sheriff Ric Bradshaw of PBSO announced the sentencing.
