Antonia Guerrero was 12 when she was taken from Tampa, Florida, on September 5, 2005. Authorities describe the case as a family abduction: Antonia and her 13-year-old sister Stephanie Guerrero and 11-year-old half-sister Sandra Lopez were taken by their non-custodial mother, Vivian Martinez. A felony warrant for Martinez’s arrest was issued on November 22, 2005.

At the time of the disappearance Antonia was 5 feet 2 inches and about 110 pounds with brown hair and brown eyes. Investigators have considered the possibility the family traveled to Mexico because Martinez has ties there, but they could also remain in the Tampa area. The case has grown cold and the family’s whereabouts remain unknown.

If anyone has information about Antonia, Stephanie, Sandra, or Vivian Martinez that could help locate them, please share what is known with the appropriate authorities.
