A forensics expert identified a woman found dead in Glencoe on Saturday as a 26-year-old Jacksonville resident, officials said, and a suspect in her death is in custody on unrelated charges.

“I subpoenaed dental records for people we thought it was and the odontologist compared those known records against the victim’s teeth,” Brown said.

Diggs said on Wednesday that investigators have one suspect in custody at the Calhoun County Jail on unrelated drug charges, but that multiple people may be involved. Williams and the suspect had been “in an ongoing type of relationship,” the chief said.

“We’re looking into that,” he said.

Williams was last seen the morning before her body was discovered, Diggs said.

“She left work at the Mapco Thursday night and went to stay at her mom’s house, her mom told us,” the chief said. “She left early Friday morning and hadn’t been seen until she was found on Saturday.”

According to the autopsy report, Williams died of blunt-force trauma to the head, Brown said.

“It appears she was burned after she was killed,” the coroner said.

Diggs on Monday said police were still unsure if Williams was killed at the scene where she was found or if she was killed somewhere else and taken to the trailer.

“We’re still searching for that other scene,” he said on Wednesday.

The chief said investigators with the Center for Applied Forensics helped canvas the scene at the trailer, and had processed no other scenes.

Diggs said a motive for the woman’s death remained a mystery.

Police are searching for Williams’ van, a white 2003 Chrysler Voyager with tag number 11HM840, the chief said.
