An Amber Alert has been issued for an Alabama toddler girl who vanished while attending a birthday party over the weekend, authorities said Sunday. Investigators fear she may have been kidnapped.
Kamille “Cupcake” McKinney, was playing with other children at an outdoor birthday party at around 8:30 p.m. Saturday night when she suddenly disappeared, said Birmingham Police Department officers.

Police said they detained a person of interest for questioning in the case late Sunday evening.
"I want her back bad, and I’d do anything to have my baby back," Dominique McKinney, Kamille's father, told Birmingham ABC affiliate WBMA. "And it’s going to get deeper than this, the city is already locked down so y’all need to bring my baby back."
Birmingham police released photos of the suspect at a convenience store on Sunday evening.
The Amber Alert issued by state authorities on Saturday said the toddler is considered to be in "extreme danger."
"We still have hot leads right now and we're following up on those as we speak," Birmingham Police Department Deputy Chief Scott Praytor told reporters Sunday. "We want to find Kamille as quick as possible and we want to get her back to her family and that's our priority."

"Of all the resources that we have at our disposal, there's nothing more important than the community," Praytor said. "We've had cases that have been broken by people that didn't think they saw anything until they came forward and told us what they knew."
"They didn't know it was a valuable piece of the puzzle. So you may think you don't know anything about it, but you may have the piece that we're looking for. We want all information."
Kamille, who is black, was described as about 3 feet tall weighing 60 pounds with brown eyes and black hair. Investigators said anyone with information should contact Birmingham police or Crime Stoppers immediately.
