Police reopened the case in July on the 3- to 5-year-old child who became known only as Baby Hope. Her body was buried in St. Raymond's Cemetery in the Bronx in 1993. The medical examiner's office was able to construct Baby Hope's DNA profile in 2011 but no genetic match was found in the databases of convicted felons or missing persons.
Law enforcement officials Monday were able to match her DNA after receiving a tip from a woman who said she thought she knew Baby Hope's sister, the New York Post reported.
After interviewing the possible sister, investigators narrowed down who they believed to the be the mother, whose DNA matched that of the body of the child, The New York Times reported.
The investigation is ongoing and so far no charges have been filed.
