BRIDGETON, New Jersey (WPVI) -- For 12 days, investigators in Bridgeton, New Jersey have been searching for 5-year-old Dulce Maria Alavez.

Dulce's face is all over Amber Alert posters, but still, she's nowhere to be found. The FBI has also recently placed Dulce on its most-wanted missing persons list.

Officers said a man led Dulce away to a red van while she played with her 3-year-old brother back on September 16 at the Bridgeton City Park.

Investigators said it happened while her mother was in the car with an 8-year-old relative.

Dulce's mother told police her son soon ran back to the car crying and pointed to the area where he last saw his sister. They looked but could not locate her.

Kimberlee Sue Moran, a teaching professor and director of forensics at Rutgers University-Camden, is not involved in the investigation but is familiar with how large-scale searches work.

"Investigators cast a wide net. Connecting the dots to what is a dead-end and what is not," she said. "In forensic science, it is all about inclusion or exclusion so what sort of suspects or scenarios can we exclude."
