UPDATE: Family says Brianna Williams out of coma, talking

The family of Brianna Williams and law enforcement officials have differing accounts of her condition on Tuesday night. Relatives say the mother of missing 5-year-old Taylor Williams is on life support, while investigators tell First Coast News she is in a medically-induced coma.

Sources said police were on their way to arrest Brianna Williams, 27, when she overdosed on pills of some kind.

According to a medical expert, being on life support or in a medically-induced coma are conditions that could overlap. Life support typically involves using a ventilator, which requires heavy sedation or a medically induced coma.

However, a medically induced coma would not necessarily mean a ventilator.

While Williams remains in serious condition at UF Health, sheriff's office patrol cars and crime scene units were on and off the hospital campus all night on Tuesday.

Family members told First Coast News Brianna Williams had been difficult to get in touch with during the months leading up to when she reported her daughter missing.

Earlier on Tuesday, search teams involving multiple agencies found human remains between the cities of Linden and Demopolis, Alabama where the search for Taylor Williams expanded. Officials haven't identified the body.
