An officer broke the window so he and his colleagues could get to the victim in a rear River Road parking lot late Friday afternoon, Detective Lt. Kevin Van Saders said.
They immediately administered CPR and then Narcan, which brought her around, he said.
The woman -- who told police she'd taken oxycodone -- was taken to Holy Name Medical Center by a hospital ambulance, Van Saders said.
The heroes: Capt. Kevin Kiene, Lt. Brian Clancy and Officers Brian Ciavaglia and Andrew Lignos.
