The Tennessee Bureau of Investigation has arrested three individuals in connection to the homicides of four people.

The TBI announced the arrests of Dearrah Sanders, 23, Tanaka Brown, 29, and Giovonte Thomas, 29, all of whom were charged with one count of accessory after the fact to first-degree murder, in connection to the deaths of James M. Wilson, 21, Adrianna Williams, 20, Cortney Rose, 38, and Braydon Williams, 15. Brown faces an additional charge of tampering with evidence, the TBI said in an updated statement. 

Authorities believe that Sanders, Brown, and Thomas “assisted” main suspect Austin Robert Drummond, who has a warrant out for his arrest on four counts of first-degree murder, one count of aggravated kidnapping, four counts of felon in possession of a firearm, and one count of possession of a firearm during the commission of a dangerous felony. He is considered armed and dangerous, authorities cautioned.

Dyer County Sheriff’s Officers discovered the four dead bodies in the woods of Tiptonville, Tenn., on the evening of July 29. Details about the suspected cause of deaths have not been disclosed to the public.

Suspect had “familial relationship” with quadruple homicide victims

The victims’ remains were discovered hours after an infant child was abandoned in a “random individual’s” yard in the neighboring community of Tigrett on the afternoon of July 29, the Dyer County Sheriff’s Office said in a Facebook post. At the time, officers sought to question Cortney Rose, the child’s maternal grandmother; Matthew Wilson, the child’s father; and Adrianna Williams, the baby’s mother, about the incident, before later finding the bodies in the woods of Tiptonville.

It’s since been confirmed that the child’s parents and grandmother, as well as the uncle Braydon Williams, are among the deceased.

“This is a deeply saddening day for our community. We are committed to uncovering the truth and ensuring justice is served,” Dyer County Sheriff Jeff Box said in a statement at the time.

David B. Rausch, the Tennessee Bureau of Investigation director, confirmed that Drummond has a “familial relationship” to the victims, but declined to share further details, according to NBC News. 

Reward money offered for information

The TBI and U.S. Marshals Office are now offering a combined reward of up to $17,500 for information leading to Drummond’s arrest.

The Jackson Police Department said in an August 1 statement that Drummond’s vehicle was found abandoned at the end of MCO Road. Drummond is believed to have been “living in the vehicle and may be in the area,” the police department added.

“JPD asks all people within the immediate area of this alert, to lock their doors and stay indoors as we actively search for Drummond,” the alert reads. “Remember, he is considered armed and extremely dangerous. If you see him, call 911 immediately.”

Anyone with information that may help in the investigation is urged to call 731-415-7962, 731-333-0811, or 1-800-TBI-FIND.
