Channel 2 Action News is trying to find out the motive in a shooting involving a woman found shot to death inside of her Cobb County home.

The incident happened inside of a home at the intersection of Mable Street and Peak Street in Mableton, Cobb County police said.

Investigators were dispatched overnight to 988 Mable Street, where they found Janice Oates, 45, dead from an apparent gunshot wound.

Her live-in boyfriend, 46-year-old Thomas Schwartz, has been arrested and faces several charges in connection with the case, including murder, aggravated assault and possession of a firearm by a convicted felon.

The victim's co-worker said Schwartz had a history of being violent toward Oates, but a neighbor said Oates was abusive toward Schwartz.

Channel 2's Amanda Cook went to Mableton to speak with neighbors about the incident. Some of them assumed the gunshot they reportedly heard during the shooting was a firework left over from the Fourth of July, until a man went running and yelling into a nearby Dairy Queen restaurant.

"Someone shot Janice. She's dead on the floor, shot to death," Lorinda Church said she heard the man, who she identified as Oates' boyfriend, yelling inside of the restaurant.

Church worked at the nearby Dairy Queen with the victim for 3 1/2 years, she told Cook. Church said Schwartz has come inside yelling several times before, smelling of alcohol.

Church said the victim and her boyfriend had a tumultuous relationship.

"I'm not surprised if he did do it. He's a bad guy," she said.

Church's mother, who frequented the Dairy Queen, described the victim as a nice woman.

"I'd go into the Dairy Queen and she was the only one I'd let make my milkshakes for me," Lora Attaway said.

The couple's neighbor, April Fleming, meanwhile, recalled instances of Oates yelling at Schwartz.

"There's two sides to every story. As far as I know, she was the abusive one to him. [She] was always assuming Thomas [Schwartz] was cheating," Fleming said, noting that Oates had recently bought a gun.

The case is still under investigation, but all of the neighbors Channel 2 spoke with did agree the couple argued loud and often. They also said alcohol played a very negative role in the couple's life.

Investigators said Schwartz is being held without bond at the Cobb County Adult Detention Center.
