ICYMI: Victim, Shooter Dead After Paulding Shooting and Standoff

DALLAS, GA -- Three people were shot, and one of them killed, before the gunman turned his weapon on himself during a shooting and standoff with police in Paulding County on Tuesday.

Jeffrey Adams, 52, of Dallas, was killed by gunfire in the shooting. Annetta "Ann" Adams, 47, of Dallas, was transported to the hospital with a single gunshot wound to the abdomen and Denise Basnett, 48, of Clarksville, Tennessee, was taken to Grady Memorial Hospital with multiple gunshot wounds.

The shooter, whom Paulding County Sheriff's deputies identified as 65-year-old William Arnett, of Powder Springs, was eventually found dead with an apparently self-inflicted gunshot wound.

At about 4:50 p.m. Tuesday, Paulding County 911 received a call saying multiple people were shot and the shooter was still firing at 65 Pine Valley Dr.

Deputies arrived and say they saw Arnett with "an AR-15 style rifle" in the backyard of 55 Pine Valley Dr.

At 5:07 p.m., Arnett began firing at deputies, authorities said.

Neighbors were evacuated and a perimeter was established around the scene as Paulding County's SWAT team was activated, along with law enforcement officers from Cobb and Douglas counties.

Once an armored vehicle arrived, officers were able to retrieve the three victims from 65 Pine Valley Dr.

Tear gas was used in an attempt to determine the shooter's whereabouts and, after no contact was made, officers sent a robot to investigate the area in and around 55 Pine Valley Dr.

That's when Arnett's body was discovered in the backyard.

Detectives learned that the Adams family was in the process of moving and had returned to their home to pick up some belongings when the shooting happened.

The attack was unprovoked, Paulding deputies say.

On Wednesday, Basnett had been through hours of surgery, with more expected. Annetta Adams' condition had improved and she was expected to be moved out of intensive care.
