Three people have been indicted in the killing of a Virginia woman whose body was found badly decomposed in a Hawkins County creek last year.

Hawkins County Sheriff Ronnie Lawson said Williams Mullins, Charles Gray and Augusta Dawn Hall are each charged with first-degree murder in the death of Callie Mahayla Ison. The three suspects are each being held on a $1 million bond.

A deer hunter found a body in a creek near East Pumpkin Valley Road in the Clinch community on Nov. 24, 2017 — the day after Thanksgiving. The body was later identified as Ison, a 26-year-old from Big Stone Gap, Virginia.

An autopsy showed Ison had been shot multiple times, the sheriff's office said. Her death was ruled a homicide.

In a statement, Sheriff Lawson said a "very intense multi-agency investigation" led authorities to the three suspects Mullins, 23, of Tellico Plains; Gray, 25, of Louisville, Kentucky; and Hall, 27, of Johnson City. He did not elaborate on how the investigation led to the three suspects or how officials believe the crime occurred.

Lawson said no further details of the case will be released at this time, and the investigation is ongoing.

Mullins is being held in the Hawkins County Jail, Gray is in custody in Louisville and Hall is currently being held in Georgia.

The sheriff's office said Gray and Hall are expected to be brought back to Hawkins County next week.
