An Amber Alert remains in effect Thursday for missing Dulce Maria Alavez, who was last seen just before 5 p.m. Monday.
Authorities said they have reports the girl was taken by a light-skinned, possibly Hispanic male, roughly 5-foot 6-inches tall. He was believed to be wearing orange sneakers, red pants and a black shirt at the time of the incident.
It's unknown if the suspect knew the girl or her family.
"Please, if you have any information help us find my granddaughter. Do not be afraid of the police," said the child's grandmother through an interpreter. "We have not been able to eat nor sleep. You can't imagine what we are going through. We are very sad. Please help our family. I beg of you."

"She would never run off. She would never walk by herself or do something like that. This is the first time she did it," said Dulce's mother, Noema Alavez Perez.
Dulce's mother reported to police that her daughter was playing on the swings with her younger 3-year-old brother, approximately 30 yards away, while she remained in her car with an 8-year-old relative.

According to the mother, the 3-year-old returned to the car without his sister and they were not able to locate her after.
"I went looking for her and couldn't find her and I called the cops," she said. "They were looking for her all night. The dogs were out here."
The last images taken of the child were with her mom and little brother buying ice cream at a nearby store just before they went to the park.
On Thursday, authorities and K9 units returned to the park to search for the missing girl.
Police also said they were interviewing possible witnesses who may have been playing basketball at the park on Monday night.

Family members have been in constant contact with authorities.
Dulce's aunt, Nayiber Alavez, says it's been very hard for the family.
"It's more harder for us because they judging us that we had something to do with it -- when we don't," she said.
The fate of the little girl has motivated many in the community joining in the search as volunteers.
People gathered in Bridgeton Park Wednesday night for a vigil praying for the safe return of Dulce. But with each passing day, some family members are losing hope she will be found alive.
"Right now, we are very sad because the child has not surfaced. We want them to return this child, it has been two days that we have no news about the girl," said Pabla Perez speaking through a translator.
The abduction has left other residents, many of them immigrants, fearful for the safety of their children.
"The truth is, we are immigrants, workers who came here solely to work in this country and we don't feel safe that someone is stealing our children," said Efren Hernandez.
