An Atlanta mom is accused of killing her 1- and 2-year-old sons by cooking them alive in an oven – and then sending their father footage of the grisly aftermath.

Investigators say Lamora Williams crammed the boys – Ke’Younte Penn, 2, and Ja’Karter Williams,1 – in the oven some time between midnight Thursday and 11 p.m. Friday, the Atlanta Journal Constitution reported.

The official cause of death is pending an autopsy.

Williams called the boys’ father, Jameel Penn, Friday night to show him live video of the crime scene – including the children lying burned on the floor – which prompted him to call 911.

“I ain’t got no soul no more,” the grieving dad said during a Saturday vigil, according to the Journal Constitution. “Ja’karter, Keyante, my world, my everything. I’m lost.”

Williams was was arrested on felony murder charges on Saturday and was ordered held without bond in Fulton County jail. She told cops that she left the kids in a sitter’s care and found the kids dead when she came home late Friday.

Relatives told the Constitution Journal that Williams suffered from an undiagnosed mental disorder.

Her 6-year-old daughter was placed in family members’ care, according to police, but it was not immediately clear where her fourth child was.

Williams did not show up to her first court appearance Monday.
