Leah Pagano, who lives on West 12 Road in Broad Channel sent her 6-year-old son to school with a box of heroin in his backpack.

A teacher’s aide at PS 209 in Whitestone, Queens, was shown the drugs by the young boy and the school contacted police at the 109 Precinct.

A Board Channel parent has been charged with possession of a controlled substance and endangering the welfare of a child after her 6-year-old son was found inside a Whitestone public school with cocaine and other drug material in his backpack.

According to court documents provided to onrockaway.com by Queens District Attorney Richard Brown, Grace Molina, a teacher’s aide at Public School 209 in Whitestone was shown a box by the Broad Channel mom’s son, 6. Inside the box, which the young student had in his backpack, was numerous glassine envelopes, pills and straws, often used for snorting cocaine.

Leah Pagano, 36, of West 12 Road in Broad Channel, the young boy’s mother, was contacted by police and admitted that the drugs were hers.

Detective Julio Hernandez of the 109 Precinct Detective Squad said in his deposition that Pagano said, “I am the only one who prepares my son’s school bag and lunch. I use heroin, but I do not shoot it. I only snort it. I could not find my box with the heroin inside. I was not sure if it was in [my son’s] school bag and went back to sleep. I can believe that I did this.”

Pagano was arraigned in Queens Criminal Court, charged with criminal possession of a controlled substance in the seventh degree, endangering the welfare of a child and knowingly acting in a manner likely to be injurious to the physical, mental or moral welfare of a child less than 17 years of age.

Pagano is due back in court on April 25 to answer to the charges.
