New surveillance video has been obtained by News 12 of the 5-year-old girl, who was believed to have been abducted, at a convenience store Monday afternoon -- about a mile away from the park where she was last seen in Bridgeton.

In the video, at one point, Dulce Maria Alavez can be seen with her little brother reaching for ice cream, and later -- Dulce picks him up while playing.

Police returned to the park in Cumberland County where a 5-year-old girl is believed to have been abducted as the search is in its fourth day today.

The FBI, Cumberland County prosecutors, Bridgeton police and a very well-trained dog returned to Bridgeton City Park around 11:30 a.m. in the search for Alavez, who has been missing since Monday afternoon. The search is in its fourth day today.

According to authorities, she was at the City Park Playground in Bridgeton with her younger brother.

Her mother was in the car nearby with an 8-year-old relative.

Police say the younger brother came back to the car without his sister. She was nowhere to be found.

On Tuesday, police issued an Amber Alert and say they believe the young girl was abducted.

Authorities say Alavez was spotted Monday afternoon in the back of a red van with a sliding side door and tinted windows. They believe she was in the company of a light-skinned, possibly Hispanic man with acne on his face. Police say that they do not have a license plate number.

Police were back at the park Wednesday looking at surveillance video and visiting the areas of the park that they believe Alavez was Monday.

They say they hope anyone who was at the park Monday contacts them so they can ask them some questions about what they may have seen. Police say they will interview as many people as they can and that they are looking at all leads – including family members.

"Sometimes tough questions have to be asked in an interview and people take offense to that because they feel you're implicating a family member or significant other, but they're just questions we have to clear up," says Bridgeton Police Chief Michael Gaimari.

The car that belongs to Alavez's mother was towed from the park Tuesday for the investigation.

The girl's family was at the park Wednesday morning asking for and praying for her return.
