Authorities are now searching for a white vehicle playing child's music after an Amber Alert was issued for a 5-year-old girl and a 6-year-old boy who disappeared while playing in front of their Jacksonville area home.

Six-year-old Braxton Williams and 5-year-old Bri'ya Williams were last seen playing in front of their home in the 10200 block of West Beaver Street in the Paradise Village mobile home park Saturday at around 11:30 a.m.

The Jacksonville Sheriff's Office says they are now looking for the driver of an older model white four-door vehicle that plays loud children's music. Tips from community members led investigators to believe the vehicle is being driven by an older white man.

Investigators don't know what connection the vehicle may have to the missing children, but want to ask the driver some questions.

"What we're hoping for is someone seen [it] somewhere else," said T.K. Waters, the chief of investigations. "[We] don't know the connection yet." Deputies are not organizing a formal community search effort at this time.

JSO Public Information Officer Christian Hancock says family members searched for an extended period of time before reporting them missing to JSO at around 1:30 p.m. Authorities say the parents were home when the children disappeared.

The children's father, Bryan Williams, told officers he was outside setting up for a bar-b-cue and the children were outside with him. He told officers he noticed his two children were no longer outside with him at around noon and he tried to find them.

"Obviously, we're at about seven hours plus that [the children] have been missing, so they could realistically be anywhere in Florida if they're not alone," Hancock said. "If they are alone, obviously, they're in danger because they're five and six years old."

At this point, JSO says they've searched more than 430 homes, more than 130 acres, and more than 20 bodies of water in the search for the missing siblings.

Investigators say the children's parents have been "100 percent cooperative," as they work to gather more information.

Police told First Coast News Braxton Williams is on the Autism spectrum but will communicate with others.

Initially, authorities reported that he was last seen in a red sweater and blue jeans, however, deputies say the red sweather was found inside their home. Bri'ya Williams was last seen wearing a gray sweater with multi-colored writing on the front and black leggings.
