A suspected quadruple murder in rural Tennessee has sparked a multi-county investigation after an abandoned infant was found safe earlier this week.

On July 29, 2025, a 7-month-old baby was discovered in a car seat outside a home in Dyer County. Witnesses reported seeing a dark minivan or white SUV drop the child off before fleeing. The infant, unharmed, was later identified as related to four people found dead on Carrington Road in Lake County the next day.

The victims were identified as James Matthew Wilson, 21; his partner Adrianna Williams, 20; Adrianna’s mother, Cortney Rose, 38; and Cortney’s son, Braydon, 15. The Tennessee Bureau of Investigation named 29-year-old Austin Robert Drummond as the suspect. Considered armed and dangerous, he remains at large, with multiple agencies — including the FBI — now involved.

Authorities have not disclosed how the victims died but confirmed the case is isolated. Family and friends are devastated, though grateful the baby was spared. “Matthew and Adrianna were the best parents anyone could ask for,” James’ father said. Investigators urge the public to remain vigilant and report any information on Drummond’s whereabouts to 1-800-TBI-FIND.
