Brianna Shontae Williams, mother of missing 5-year-old Taylor Rose Williams, was released from the hospital Thursday and booked into the Duval County Jail.
Police released a mugshot that shows Williams wearing a red jumpsuit instead of the standard issue grey or green jumpsuit.
The Jacksonville Sheriff's Office told First Coast News that a red jumpsuit means the inmate is a "possible self harm, high escape risk, or medical transport."
Williams was hospitalized after swallowing an overdose of prescription drugs the day police found the skeletal remains of a small child believed to be Taylor.
Williams, 27, reported Taylor missing in early November from her home in Jacksonville, Florida.
The skeletal remains were found on Nov. 12 in a wooded area in Demopolis, Ala., near Williams' hometown of Linden, Ala. The state of decomposition indicates the remains had been there for months.
The Jacksonville Sheriff's Office is awaiting a positive identification. But investigators are still collecting human remains that were scattered around the area by animals.
The Sheriff's Office secured the property as a crime scene and patrol vehicles keep watch 24/7, according to First Coast News.
Investigators believe a black garbage bag found at the scene once contained the little girl's body. Investigators also found clothing in the garbage bag that did not match the description of the clothing that Williams said Taylor was last seen wearing.
Forensic Expert Michael Knox told First Coast News identifying the remains is a tedious process due to the body's state of decomposition.
"It's a very painstaking process because you have to do it in small layers," Knox said. "You sift through everything in that area, you make sure no evidence is missing. Investigators are not in a hurry, they want all the data, all the information before they make a decision."
Knox said it's a "telltale sign" for JSO to put in the arrest warrant that Taylor hasn't been seen since May.
"The coroner's position would be if, in fact, it's clear to them that this child was dead long before the time that she was supposedly last seen by the mother," Knox said. "That would be enough to show that the mother is doing something wrong here, that would tend to indicate some foul play."
Williams was a high achieving honor student who graduated number 1 in her class from Linden High School in Linden, Ala. She was a Petty Officer assigned to the Naval Air Station in Jacksonville at the time of her arrest.
