Jacqueline Vasquez was four months old when she disappeared from a swap meet in Avondale, Arizona, on May 6, 2001. She was last seen wearing a white outfit and white socks. A distinctive heart-shaped birthmark on her upper right arm is noted as an identifying feature.

Authorities including the Avondale Police Department and the National Center for Missing & Exploited Children have continued the search. Investigators have used age-progressed images over the years to help the public recognize how she might look now, but no concrete information about her whereabouts has emerged.

The abruptness of a toddler vanishing from a public place and the lack of clear witnesses left many questions unanswered. Anyone who was at the swap meet that day or who may recognize Jacqueline from age-progressed photos is asked to come forward with information.
