An Amber Alert has been issued for a 4-year-old boy who was last seen in Jupiter.
The Florida Department of Law Enforcement said Dominic Caprio was last seen Thursday afternoon in the 100 block of Regions Way in Jupiter.
Investigators said Dominic may be in the company of Elizabeth and Luis Caprio.
Jupiter police confirmed to Local 10 News that Dominic's nanny, Blanca Castro, was arrested in connection with the boy's disappearance.
Castro was booked into the Turner Guilford Knight Correctional Center in Miami-Dade County early Friday morning.
Dominic's mother said she left her son with Castro, but when she returned home about an hour later, the child and nanny were gone.
Investigators said Dominic was wearing a gray pajama top with dinosaurs and green shorts. Dominic has a red or pink birthmark on the back of his neck.
Authorities believe Dominic may be traveling with Elizabeth and Luis Caprio in a blue 2013 BMW 740i with Florida license plate number CBD-B47.
Anyone with information as to their whereabouts is urged to contact police.
