An Amber Alert was issued for two siblings last seen playing in their Jacksonville yard
Braxton Williams, 6, and his sister Bri'ya Williams, 5, were reported missing around 11:30 a.m. Sunday after family members couldn't find the pair, Jacksonville Sheriff Public Information officer Christian Hancock told reporters during a press conference Sunday night.
FDLE issued an Amber Alert and the Jacksonville Sheriff's Office has launched a search that includes K9's, air units, drones and dive teams in an effort to find the children, Hancock said.
"We're searching the surrounding areas, we're searching ponds, we're searching trashcans, we're searching everything. Again we're searching for these kids and we aim to find them," Hancock told reporters.
"They could realistically be anywhere in Florida if they're not alone," Hancock said. "If they are alone obviously they are in danger because they are 5 and 6 years old."
Hancock is urging residents to be vigilant and report anything suspicious or any sightings of the missing children.
Braxton was least seen wearing a red sweater with blue jeans and Bri'ya was last seen wearing a grey sweatshirt with colorful writing on the front and black leggings, the amber alert said.
This is a developing story and CNN will update it as more information becomes available.
