An Atlanta mom has been accused of murdering her two young sons by placing them in an oven and turning it on, according to multiple local news reports.

Lamora Williams, 24, waived a court appearance Monday and was denied bail after she was arrested on charges of two counts of murder Friday. Details about her children’s cause of death were not released by authorities but preliminary investigation suggested the boys —2-year-old Ke’Younte Penn and 1-year-old Ja’Karter Williams — “received burn marks on their bodies at some point, possibly from the stove.”

The arrest warrant, according to the Atlanta Journal-Constitution, said Williams put her sons in the oven sometime between midnight Thursday and 11 p.m. EDT Friday. She then called their father, Jameel Penn, and showed him on video that there was something wrong at her home.

Penn told AJC he immediately called the police after Williams panned the camera around he could see his sons on the floor. “After I seen what I seen, you know I called the police,” he said.

"It was like a real horror movie. It was Friday the 13th," he told ABC affiliate WSB-TV. “When I saw my kid, how I saw my kid, that's when I knew what was going on. I ain’t got no soul no more."

A three-year-old was also found in Willams' house when the police arrived at the scene. He was unharmed.

According to reports, Willams suffered from undiagnosed mental health problems that were made worse after the death of her father when she was 19. Family and friends told reporters Williams was a single mother of four kids and this added to the stress. She had some help from Penn, but not enough, given the state of her mental health.

Her longtime friend, Neesa Smith, told AJC that Williams had quit a job about a month ago because she was unable to find a babysitter for the kids. She added that Williams called her before Penn on Friday and said, she “couldn’t do it anymore.”

“Nobody could tell what she was going through,” Smith said.

After the incident, when Smith insisted that she give her more details, Williams apparently said the children were dead. Smith said she had asked her friend to call the police, but she called made a video call to Penn instead.

According to the police, Williams stated she had given her children to a caregiver Friday noon and came back home later in the evening to find the children dead and the caregiver absent. However, the police said they did not believe Williams' story.

Her sister, Tabitha Hollingsworth, told AJC that Williams should be put on suicide watch in the Fulton County jail, where she was being held. Hollingsworth also said her sister suffered from an undiagnosed mental illness even as a child and no one listened to her mother’s pleas when she wanted to seek help for Williams, she told Daily Mail.

“Teachers would say something was wrong, but the state said nothing was wrong. This is something the state didn’t recognize. The whole state really failed us.She’s the only one who really knows what happened,” Hollingsworth said.
