It's been about a week since 5-year-old Taylor Rose Williams was reported missing to police.

The child was reported missing by her mother, Brianna Williams, 27, on Wednesday, Nov. 6 around 7:20 a.m. Brianna Williams told police she last saw her daughter around midnight in their Brentwood home in the 600 block of Ivy Street. 

The Florida Department of Law Enforcement issued an AMBER Alert for her, which is still in effect. The search for her has now expanded to include Alabama and involve multiple agencies, JSO said.

Here are the 10 major things you need to know in the search for Taylor:

1) Brianna Williams arrested, charged with child neglect, giving false information to police, held on over $1 million bond

About a week after 5-year-old Taylor Williams was reported missing, her mother, 27-year-old Brianna Williams, was arrested and charged with child neglect and giving false information to investigators on Tuesday, Nov. 12.

These charges come after a child's remains were found in a wooded area between Linden, Alabama and Demopolis, Alabama with "indications it may be Taylor Williams," Jacksonville Sheriff Mike Williams said.

"The exact identification of the victim will be made pending some detailed forensic analysis of the remains," the sheriff said.

He declined to go into detail about the nature of the charges against Brianna Williams saying it could impact the investigation.

According to her booking information, Brianna Williams is being held on a $1 million bond.

2) Brianna Williams hospitalized after apparent overdose after child remains found

On Tuesday, Sheriff Williams also confirmed that Brianna Williams is currently in the hospital with serious injuries from an apparent overdose.

A close family friend to Petty Officer Brianna Williams - who wished to remain anonymous - told First Coast News that the mother overdosed after a child's remains were found and when police were on their way to arrest her. 

Brianna Williams was flown by helicopter to the hospital, the friend said.

The identity of the remains hasn't been confirmed. Authorities are waiting on forensic tests.

3) JSO Sheriff confirms child remains found in Alabama during search for Taylor Williams

Search teams uncovered human remains in a wooded area between the cities of Linden, Alabama and Demopolis, Alabama while they were searching for missing 5-year-old Taylor Williams.

During a news conference on Tuesday, the Jacksonville sheriff said the remains were of a child and that there are "indications it may be Taylor Williams."

Mike Williams and other officials have not confirmed the identity of the body. The mayor of Demopolis, John Laney, said they are waiting on forensic tests to confirm the body's identity.

4) Mother Brianna Williams became person of interest after she stopped cooperating with police

During a news conference on Monday, Nov. 11, Jacksonville Sheriff Mike Williams said Brianna Williams is still not cooperating with police and is now considered a person of interest. 

"She's not spoken to us since [last] Wednesday," he said. "She was the last person to see Taylor ... We still need her cooperation."

Last week, the sheriff said, "We were talking to (Brianna Williams) about some inconsistencies in her statement and that's why she chose to stop cooperating with us."

5) Search began in Jacksonville, Fla. and expanded into Alabama

Last Wednesday, the search started at their Ivy Street home and expanded to Brianna Williams' prior address at 7651 Paradise Island Blvd. on the Southside. During this time, more than 300 officers and personnel assisted with the search, including K9, dive team and mounted horse units.

On Sunday, JSO tweeted that the search now expands into three states: Florida, Georgia and Alabama. Though Sheriff Mike Williams didn't go into detail about Georgia, he did say on Monday that JSO deployed officers near the vicinity of Demopolis, Alabama, primarily investigators with its homicide unit and missing person's unit.

6) Multiple agencies now involved in the search

Because the search has crossed state lines, multiple agencies are now involved in the search for Taylor Williams.

The agencies involved include:

  • Demopolis Police Department
  • Demopolis Fire Department
  • Linden Police Department
  • Marengo County Sheriff’s Office
  • Alabama Law Enforcement Agency State Bureau of Investigations
  • 17th Circuit Drug Task Force
  • 17th Circuit District Attorney’s Office
  • Alabama Attorney General’s Office
  • FBI from Mobile, Birmingham & Jacksonville Offices
  • Members of multiple units with the Jacksonville Sheriffs Office, Jacksonville Fire and Rescue, as well as the State Attorney’s Office

7) Police release picture of Brianna Williams' car, ask public if they were seen together in the past two weeks

On Monday, Nov. 11, police released a photo of Brianna Williams' car asking anyone if they've seen Brianna Williams and Taylor Williams together over the past two weeks between Jacksonville, Fla. and Alabama. This request is different from last Thursday’s – which covered the past six months in Jacksonville – because of new information and a different lead, he said.

“While it sounds similar, it’s a different request,” he said.

Police believe Brianna Williams traveled to Alabama recently, but didn’t go into details of when or why. However, they believe the mother was traveling in her black 2017 Honda Accord with tinted windows and rims, Mike Williams said.

8) Taylor's Father: "It's been a minute" since he saw the child

The father of Taylor Williams, Maurice Tate, spoke to First Coast News by phone, saying "it's been a minute" since he last saw his daughter.

The father lives out-of-state. He said he's been in communication with JSO, but didn't give an indication if he intends to come to Jacksonville.

9) Couple claims they never saw a child

Tiffani Nicole said she and her fiancé responded to a Craiglist ad by Brianna Williams on Sunday asking for help moving into her Brentwood area home from the Southside apartment complex. 

While helping her move in, Nicole said she never saw Taylor Williams during the move.

"The strange thing that was off to me was she told my fiancé there was a daughter in the bathroom and he heard water running," she said. "We never saw a child ... we did load up a pink and purple toddler bed."
