Dulce vanished from a Bridgeton park on September 16, 2019 while she was on the playground with her brother. Her mother, Noema Perez-Alavez, was nearby but couldn't see her daughter playing before she was kidnapped.
ICE Newark released a statement this week on the disappearance, saying that those living in the community illegally "should not for one minute be hesitant to provide information that may assist in this investigation."
"ICE officers are trained to exercise prosecutorial discretion in performing their immigration enforcement duties. Indeed, federal immigration law makes certain forms of immigration benefits available under certain circumstances to individuals who assist law enforcement or who have been victimized by criminal activity," added ICE (U.S. Immigration and Customs Enforcement).
The FBI tells Action News that there were witnesses who likely saw the person who abducted the little girl.
"The person that did this likely lived in Bridgeton, been familiar with Bridgeton or had a reason to be where they were in that park," said FBI special agent Daniel Garrabrant.
Alavez-Perez said earlier this month that she regrets letting her daughter leave her sight.
"It gives me bad memories because I wish I could go back to the time and come with her to the park and not leave her alone," she said.
Noema adds the community has supported her over the last year, but there have been many critics.
She says she has nothing to hide and will continue to speak until her daughter comes home.
"I'm grateful for them because not a lot of people are helping my family, support us, looking for Dulce," she said. "There's a lot of people judging me, my family, saying we had something to do with it, but we had nothing to do with it."
There is a $75,000 reward being offered in the case.
