"Then I broke down thinking about the child," the mother of five told KHON-TV.
The fingers, which Vendegna found last month, are likely from a girl who's 2 1/2 to 4 years old, Honolulu police said.
Residents of the 389-unit Kukui Gardens complex near downtown Honolulu and Chinatown are abuzz about the find, which came to light when police asked the public for help this week, said Kevin Carney, Hawaii vice president for EAH Housing, the San Rafael, California-based company that manages the affordable rentals.
Twenty buildings are on about 10 acres (4 hectares) dotted with palm trees, and while the complex is in an urban neighborhood, there is little crime, Carney said. "It's a peaceful, quiet community. The crime would shock any community," he said.
There have been no reports of missing children, he said. Police have interviewed area residents and checked missing reports, but have no leads.
