A 20-year-old woman was discovered dead inside a Bronx housing facility, cops said.

The woman, whose identity was not yet released, was found unconscious and unresponsive inside the Parkside Houses on Arnow and Barker avenues around 8:30 a.m. Saturday, cops said.

Police sources said the woman may have overdosed on prescription pills, however it wasn’t immediately clear what kind and the medical examiner will have to make that determination.
