A fourth person is now facing federal charges in connection to the death of a 1-year-old and the poisoning of three other children at a Bronx day care, officials said Thursday. 

Felix Herrera Garcia, 34, was apprehended Tuesday afternoon in Sinaloa, Mexico. 

Herrera Garcia faces charges of federal conspiracy to distribute narcotics resulting in death and possession with intent to distribute narcotics resulting in death, according to a criminal complaint provided by the U.S. attorney’s office for the southern district. Both charges carry a mandatory minimum sentence of 20 years in prison and a maximum sentence of life in prison. 

Authorities say Herrera Garcia is the husband of 36-year-old Grei Mendez, the woman who officials say was the owner of the day care where four children were poisoned by a substance believed to be fentanyl. 

Mendez and another suspect, Carlisto Acevedo Brito, 41, face federal charges of one count of conspiracy to distribute narcotics resulting in death and one count of possession with intent to distribute narcotics resulting in death. Both counts carry a mandatory minimum sentence of 20 years in prison and a maximum sentence of life in prison. 

According to officials, Acevedo Brito lived in a room inside the day care center that was locked.

A fourth suspect, Renny Antonio Parra Paredes, 38, faces one count of federal conspiracy to distribute narcotics resulting in death. The charge carries a mandatory minimum sentence of 20 years in prison and a maximum sentence of life in prison. 

According to prosecutors, the couple, along with Acevedo Brito and Parra Paredes, conspired to distribute fentanyl at the day care center from at least July through September. “Large quantities of narcotics” were kept at the site of the day care, including a kilogram of fentanyl stored on top of playmats, and more narcotics were hidden in “trap” compartments near an area where the children played and slept, according to the criminal complaint.

Three of the children had the effects of their poisoning reversed by Narcan, but the fourth, a 1-year-old boy, died of his injuries, according to the criminal complaint.

The criminal complaint alleges that Herrera Garcia exited out of the back alley of the day care center with two shopping bags before emergency personnel arrived at the scene, which the criminal complaint alleges “is consistent with the behavior of an individual attempting to remove materials from the day care to avoid their discovery by law enforcement.” Photographs of a person alleged to be Herrera Garcia are included in the complaint.
