Jacksonville, Florida, police searched Tuesday for two children reported missing during the weekend while playing outside their mobile home.

Sheriff's deputies resumed their search for Braxton Williams, 6, and his sister Bri’ya Williams, 5, at 11 a.m. The search was called off Monday night due to poor weather.

WJXT-TV of Jacksonville reported dozens of volunteers came out to augment police search efforts, but Jacksonville Sheriff’s Officer Chris Hancock said while police are grateful, volunteers wouldn’t be needed due to the weather.

Braxton and Bri’ya were first reported missing Sunday afternoon after last being seen at Paradise Village Mobile Home Park. The siblings reportedly were playing outside around 11:30 a.m. and failed to return home. A relative contacted police around 1:30 p.m., saying the two hadn’t been seen for nearly two hours with no mention of where they could have gone.

An amber alert was issued around 5:15 p.m. Sunday by the Florida Department of Law Enforcement.

“Foul play could be a factor at this point. We just don’t know,” Jacksonville Sheriff Mike Williams told a press conference Monday. “We’ve got no indication that anyone close to the children is involved.”

The disappearances have frightened parents in the surrounding area.

Paradise Village resident Ashley Palmer told WJXT she brought her daughter Alaya, 6, to the scene of the disappearance teach her a lesson in wondering off.

“I brought her out here because I have tried to explain her numerous times that there are mean and evil people out here and they’re out here harming our little ones and for her to listen when I say: ‘Don’t go anywhere. Don’t take off,’” Palmer said. “She has a really bad tendency to want to take off.”
