Carmen Milagros Davila and Angel Marcos Rodriguez of Allentown were arrested on drug charges Wednesday.
A drug investigation led Allentown vice officers to obtain a warrant to search their residence at 458 Washington St. on Wednesday afternoon.
Davila, 55, was charged with possession of heroin, possession with intent to deliver heroin and possession of drug paraphernalia. That included a digital scale, small zip-lock bags and small glass containers used for weighing and packaging drugs.
Police said Davila, who was home at the time, admitted to police that she had heroin in her home and showed them where it was located. Police reported they recovered "half a bundle" of the drug.
Rodriguez, 24, also was charged with possession of drug paraphernalia.
And he was charged with possession of a firearm, identified as a hi-point 9 mm handgun.
Police said Rodriguez was not allowed to have a handgun because, when a juvenile, he was charged with possessing a weapon on school property.
