Search for Dulce Maria Alavez continues 2 months after she vanished from a New Jersey playground
WATCH: Authorities have released a composite sketch of a possible witness in the case of missing 5-year-old Dulce Maria Alavez.

Saturday marks two months since a 5-year-old girl vanished from a New Jersey playground.

Dulce Maria Alavez was last seen on Sept. 16 playing in a Bridgeton park with her little brother as her mother sat in a car nearby. Since then, the Bridgeton Police Department, the Cumberland County Prosecutor's Office and the FBI have been investigating her disappearance, while the little girl's family has led its own door-to-door search.

An Amber Alert has been issued for Dulce Maria Alavez, 5, in Bridgeton, N.J.

A reward of $52,000 -- from a mix of law enforcement and local businesses, among others -- has been offered for any information.

On the day she went missing, Dulce was playing with her 3-year-old brother at Bridgeton City Park in the afternoon while her mother, Noema Alavez Perez, sat in a car with an 8-year-old relative doing homework.

At some point, the little boy returned to the vehicle, but without Dulce.

An Amber Alert was issued that night, and authorities later asked for information about a man described as standing about 5-foot-6 inches tall and wearing orange sneakers, red pants and a black shirt. Police said he may have led Dulce from the playground to a red van with a sliding door and tinted windows.

"She’s just an innocent girl. She’s just 5 years old. She doesn’t know nothing of the world that we know," Perez said during a news conference on Sept. 30.

On Oct. 15, investigators released a sketch of a possible witness who was allegedly at the park at the time Dulce went missing, but have yet to find that person.
