Authorities in Alabama say they’ve expanded the search for a missing 3-year-old girl to include surrounding states, including Tennessee and Georgia.

Birmingham Mayor Randall Woodfin and police Chief Patrick Smith spoke to reporters at a Monday news conference about Kamille McKinney, who authorities say was kidnapped from her birthday party on Saturday by a stranger in a dark SUV.

She was last seen wearing a pink T-shirt with a leopard print Minnie Mouse face, leopard print shorts with no shoes.

Smith says there was a multi-hour delay before an Amber Alert was issued in the kidnapping of the girl nicknamed “Cupcake.” He says the belated alert was because of a delay in when the kidnapping was reported to law enforcement.

Smith says the FBI is assisting and two people of interest are undergoing questioning. Both were taken into custody Sunday after authorities found a vehicle recorded by a surveillance camera.
