Princess was last seen at her family's residence on Webb Avenue in the New York City borough of the Bronx on June 15, 1996. Officials with New York's Administration Of Children's Services (ACS) had been investigating the Perez home for several months prior to Princess's disappearance. ACS workers last saw the child on June 15; she was in the company of her father, Antonio Perez, at the time. ACS officials returned to the Perez family's residence in August in response to a report that Princess was missing. They were told by her mother, Karen Perez, that Princess was living in California with Karen's mother. The ACS was unable to locate the child, but Karen stuck by her story that Princess was in California and no further investigation was made at that time.
