WATCH Possible witness sketch released in case of Dulce Maria Alavez

Authorities released a sketch on Tuesday of a man they believe may have information on 5-year-old Dulce Maria Alavez, whose disappearance nearly a month ago from a New Jersey park has left few answers.

Cumberland County Prosecutor Jennifer Webb-McRae identified the man in the sketch as a "possible witness" to Dulce's disappearance and someone who they want to speak with, according to a press release from her office.

Webb-McRae made a point to note that she is not calling him a suspect or person of interest.

He was allegedly at the park around the time Dulce went missing. A witness recently came forward with his description and told authorities that he was seen with one or two children under the age of 5 years old. It was not immediately clear if one of the children was Dulce.

Webb-McRae did not immediately respond to ABC News for comment.

Dulce was last seen on Sept. 16 in the afternoon near City Park in Bridgeton, New Jersey.

Dulce's mom, Noema Alavez Perez, said on the day her daughter vanished, she was in the car scratching off a lottery ticket while her daughter was playing on the swings with her 3-year-old brother, about 30 yards away.

Perez said she could see the park, but not the swings because hills were blocking them. When her son returned to the car, Dulce was nowhere to be found.

Federal, state and local officials have all been involved in the search for the little girl, but there has been no clear indication as to what happened to her.

Webb-McRae asked the man in the sketch, or anyone who recognizes him, to come forward.

He is believed to be between 30 to 35 years old and around 5-foot-7 with a slender build. He was wearing a white T-shirt, blue jeans and a white baseball-style hat at the time of Dulce's disappearance, according to the prosecutor's office.
