Authorities have revealed new details regarding the Tennessee man believed to be connected to a brutal quadruple murder after a baby was found abandoned on the front lawn of a home earlier this week. 

A manhunt is underway for 28-year-old Austin Robert Drummond, who allegedly killed James M. Wilson, 21, Adrianna Williams, 20, Cortney Rose, 38, and Braydon Williams, 15, according to the Dyer County Police Department.

The four were found on Tuesday in Tiptonville, Tennessee, located roughly 125 miles from Memphis. 

“It was a targeted attack,” Danny Goodman Jr., attorney general for the 29th Judicial District of Tennessee, told “Fox & Friends” on Friday. “We don’t think there’s a need for the community to be concerned, as far as it being some type of random act or anything like that.”

“We have strong evidence that we know this is the person who was at the scene,” Goodman said. 

Drummond is wanted for alleged first-degree murder, kidnapping, four counts of a felon in possession of a firearm and one count of possession of a firearm during the commission of a dangerous felony. 

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

Local officials have asked the public to remain on the lookout for Drummond, who is considered to be “armed and dangerous.” Drummond is described as 5-feet, 10-inches tall and weighing 190 pounds, with brown hair, blue eyes and a goatee. He is believed to be driving a 2016 Audi A3 with Tennessee license plate RI 01896 and damage to the driver’s side.

TBI and the Dyer County Police Department did not immediately respond to Fox News Digital’s request for comment. 

Anyone with information about Drummond’s whereabouts is encouraged to contact the Dyer County Police Department by calling (731)-285-2802 or 1-800-TBI-FIND.
