A reclusive Brooklyn mom stuffed her dead 1-month-old son in a duffel bag and stashed his tiny body in a closet — horrifying her unsuspecting neighbors, police and sources said. Gynae Kendall, 25, was charged Sunday with concealment of a human corpse, one day after police said they found little Adonnys unresponsive inside the Flatbush apartment. Cops made the grisly discovery after the baby’s maternal grandmother called the NYPD and asked them to conduct a wellness check late Saturday, telling police she was worried after not seeing the boy for some time, according to law enforcement sources.
