The husband of the owner of the drug-filled Bronx day care was arrested in Mexico

The husband of the owner and operator of the Bronx day care where a 1-year-child died of suspected fentanyl exposure has been captured by authorities in Mexico, multiple US law enforcement sources familiar with the search told CNN on Tuesday.

Felix Herrera Garcia, husband of Grei Mendez, was on a bus in the city of Sinaloa when he was taken into custody by Mexican authorities and US Drug Enforcement Administration agents Tuesday, one of the sources said.

Herrera is in the custody of US Marshals, who will handle his extradition to New York.

Authorities in the US have made three prior arrests after 1-year-old Nicholas Dominici died earlier this month following the suspected fentanyl exposure at Divino Niño day care center. Three other children - two 2-year-old boys and an 8-month-old girl - were hospitalized after being exposed to the suspected fentanyl and suffered acute opioid intoxication, officials said.

Authorities discovered a trap floor containing drugs, including fentanyl, inside the day care, the New York Police Department announced last week.

A New York City grand jury voted Thursday to indict Mendez, 36, and Carlisto Acevedo Brito, 41, according to Bronx District Attorney Darcel Clark, who didn't specify the charges. On Monday, Renny Antonio Parra Paredes, 38, was charged in federal court in Manhattan with one count of conspiracy to distribute narcotics resulting in death.

CNN has reached out to their attorneys for comment.
