The Tennessee Bureau of Investigation announced Thursday that they are searching for a man in connection with the deaths of four people and an abandoned infant.

A warrant has been issued for 29-year-old Austin Robert Drummond. He’s charged with four counts of first-degree murder, kidnapping, and related charges, according to a TBI news release.

“At this time, Drummond remains at large and should be considered armed and dangerous,” the TBI said.

As CrimeOnline previously reported, TBI identified the victims of the homicide as 15-year-old Braydon Williams, 21-year-old James Matthew Wilson, 20-year-old Adrianna Williams, and 38-year-old Cortney Rose.

Police found their bodies were found along Carrington Road in Tiptonville on July 29.

Investigators said the victims were related to a 7-month-old girl found in a car seat in a front yard in Tigrett earlier in the day.

According to Facebook posts, Wilson and Adrianna Williams are the baby’s parents, Rose is Williams’ mother, and the teen is Williams’ brother.

Dyer County deputies quickly identified the child and announced they were looking for the parents and Rose. Hours later came the discovery of the bodies.

“A dark-colored minivan or a white mid-size SUV was reported to have dropped off an infant in a car seat at a random individual’s front yard,” the Dyer County Sheriff’s Office said on July 29.

Authorities indicated that the killings were not random.

“Drummond is 5’10”, 190 lbs., brown hair, blue eyes & a goatee,” TBI said. “He’s believed to be driving a ’16 Audi A3 w/TN tag: RI 01896, with damage to the driver’s side.”

According to the Tennessee Department of Correction, Drummond has a criminal history, with convictions that include aggravated robbery and retaliation for past action. He spent 13 years behind bars and was released last year.

FOX 13 Memphis reports that the TBI placed Drummond on the Tennessee Most Wanted list, with a reward of up to $2,500 for information leading to an arrest.

Meanwhile, the outlet reports that a family member of the victims posted on Facebook that Drummond was “close to our family” and had previously dated Cortney Rose’s sister.

Anyone with information on his whereabouts should contact 731-415-7962, 731-333-0811, 1-800-TBI-FIND, or 911.
