Bernadette Rivera, 32, had several felonies worth of narcotics, including heroin and methamphetamine, on her reportedly near her private area, sources told KENS-TV.
During the search, Rivera openly told officers of the fetus in her purse and explained that she recently had a miscarriage.
The fetus was estimated to be about 8 weeks old.
Detectives determined that Rivera's possession of the fetus was not a criminal case and she is only being charged with possession of narcotics.
The Medical Examiner's Office is in contact with Rivera's family and they are working on funeral arrangements.
