Police have continued to pull over any red vans they see in the area, as one lead police has been that a man led Alavez from the playground to a red van with a sliding side door and tinted windows.
"At this point in the investigation, we continue to consider all possibilities. We remain hopeful that we're going to find Dulce alive," Webb-McRae said, adding that authorities are seeking to speak with the little girl's father.
Dulce's father is believed to be in Mexico, police initially said, but his exact location remains unknown and authorities have not said in recent days if he has been in contact.
"I'm not sure there's ever been so many police officers in Bridgeton," Deacon Arnaldo Santos of Holy Cross Parish said Monday.
"We're giving moral support and prayer, having vigils and praying the rosary," Santos said. "They know the doors of the church are open to them."
The boyfriend, a 27-year-old Mexican citizen, "is part of an ongoing investigation by local, state and federal law enforcement partners and ICE cannot comment further," ICE spokesman Adrian Smith said in a statement last week, refusing to confirm whether the investigation into the boyfriend involves Alavez's disappearance.
