During a press conference around 10:30 a.m., the Jacksonville Sheriff's Office said it had about 100 officers and other personnel searching for Taylor Williams. Police expanded the search area and crews are going door-to-door in the neighborhood. 

"A police officer came to my house this morning with the flyer," said Zion Newsome, a resident in the area. "As soon as he hit me with the flyer, let me know the information, I came in the neighborhood and started looking for myself ... Me being a father, me being part of the community, this is important that we have to stand up and protect our people in any respect that we could possibly do."

"I came down actually to help out with the efforts passing out water, sodas, things like that, keep everyone hydrated," said Robert Simmons.
