The missing girl is now eight years old. She was just five when she disappeared from Bridgeton City Park in 2019.

Her family and law enforcement still have hope that she is alive.
"In the absence of evidence to the contrary, we hold out hope that she is alive. This is an ongoing investigation," said the Cumberland County Prosecutor's Office in a statement.
The party decorations were Moana-themed -- one of her favorite movies.

"Her birthday's today. She's supposed to be eight, and she's not here with me or my family and that's hard," said the girl's mother, Noema Alavez-Perez. "I feel sad, empty that Dulce's not here today."
Police say the girl was playing in the park with her brother Manuel behind the Bridgeton High School on September 16, 2019, when she disappeared.
Dulce's mother was in her car while the children played, and that's when the girl vanished.
Alavez Perez said in a previous interview with Action News 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.
A day after Dulce was kidnapped, authorities issued an Amber Alert with one key suspect characteristic: a man in a red van.
Investigators scoured the area for signs of Dulce and that red van. Police and the community participated in search after search in hopes of finding any key piece of evidence. Nothing has ever been found and no red van has ever been located that could be connected to Dulce, according to authorities.

Two descriptions of a possible suspect started to emerge early in the investigation.
According to the Amber Alert, which was derived from initial witness accounts, Dulce may have been taken by a light-skinned, possibly Hispanic male who is 5'6" to 5'8" tall, thin build, no facial hair, but has acne on his face. He was seen wearing orange sneakers, possibly Nike, red pants, and a black shirt.
A month later, on October 15, 2019, police released a composite sketch, describing the man as Hispanic, roughly 5'7", slender build, roughly 30-35 years old. He last seen wearing a white T-shirt, blue jeans and a white baseball-style hat.
Bridgeton Police Chief Michael Gaimari Sr. says there were more than just children on the court that day and witnesses were re-interviewed. This helped authorities provide a more accurate depiction of the person that could bring some answers in the case.
The FBI says the public should be on the lookout for a young Hispanic male, roughly 25 to 35 years old who was seen in the area of the playground.

In September 2021, a walk and vigil were held to mark the two-year anniversary of her disappearance. Police also released a new age-progression photo of what Dulce might look like today.
The National Center for Missing and Exploited Children says observing milestones like birthdays or anniversaries for missing people can help to keep the public aware.
The organization created the two different age-progressed photos of Dulce in hopes that someone may recognize her.
Dulce's father, who lives in Mexico, was questioned during the initial investigation. He has repeatedly denied having anything to do with her disappearance.
