A Missouri tot vanished while riding her bike on Saturday, and police and the FBI are still searching for her.

Officials are investigating a suspicious older model white van that was seen in the area.

"These are the kinds of leads we get," Senath police chief Omar Karnes said. "We chase every one of them. Maybe we can locate this van." 

Breeann Rodriguez, 3, was riding her bike with her 5-year old brother outside of their house in the town of Senath, according to the FBI.

Their mother was inside of the house.

"They were both on their bikes, and then he stopped and went in the house to get a drink while she stayed outside," FBI spokesperson Rebecca Wu said.

Breeann was riding a pink bicycle with training wheels. It was left behind.

Breeann is Hispanic, 34 inches tall, and weighs about 30 pounds. She has brown eyes and long black hair.

She was wearing a pink top and pink and purple pants.

Senath has a population of less than 2,000.

Police urge anyone with information to call 866-371-TIPS.
