Neighbors told police that a 4-year-old girl was going door-to-door trying to sell a brick of marijuana.
Maria Ipina has been charged with possession of a controlled substance after her Monday arrest. A San Juan police dispatcher declined to release any information Tuesday night on Ipina.
Gonzalez said police found more than 200 grams of cocaine packaged for sale, but no marijuana in Ipina's apartment.
Gonzalez said the girl and her 6-month-old sibling have been turned over to Ipina's mother. No attorney has been listed for her.
