Authorities searching for a 5-year-old girl believed to have been kidnapped from a Cumberland County park last week are asking anyone who visited the site that day to share photos or videos they took in the area.

Dulce Maria Alavez disappeared Sept. 16 from a playground at Bridgeton City Park. Cumberland County Prosecutor Jennifer Webb-McRae announced Monday that a special FBI website was created for the public to upload pictures and videos from the day the girl went missing.

“We are asking anyone who may have been at the Bridgeton City Park Recreational Area on Monday, Sept. 16, 2019 between the hours of 3 p.m. and 6 p.m. to check their cell phones…Their media may contain information which seems innocuous to them but is a valuable piece of the puzzle in helping us bring Dulce home to her family,” Webb-McRae said in a statement.

Alavez and her 3-year-old brother were playing while their mother sat in her car with an 8-year-old relative.

The 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.

An Amber Alert was issued the following day. Authorities believe the girl was taken by a man who led her to a red van.

There's a $35,000 reward for information leading to an arrest in the case.
