A manhunt is underway for a 29-year-old man who allegedly killed four people and left their baby alive, Tennessee authorities said.

The four were found dead hours after the baby daughter of Wilson and Adrianna Williams was found abandoned Tuesday afternoon in a car seat in a “random” front yard near the Dyer County community of Tigrett, nearly a 40-mile drive southeast of Tiptonville, authorities had said.

Austin Robert Drummond, 28, faces four counts of first-degree murder, one count of aggravated kidnapping and firearms charges.
