Two were arrested in Worcester Friday night for possession of over 100 grams of Fentanyl in an apartment with a 3-year-old child.
Reinaldo Monserrate, 33, and Nicole Auger, 24, are charged with trafficking a Class B substance.
An unnamed 19-year-old female was also inside the apartment at the time of their arrest.
A third suspect involved in the investigation was not located at the scene. The suspect is still at-large and police are withholding the person's name until their arrest.
Along with the Fentanyl, officers found $400 in cash and a digital scale.
Monserrate and Auger will be arraigned on Monday at the Worcester County District Court.
Due to the living conditions in the apartment, police filed a report of abuse or neglect with The Department of Children and Families.
