A 4-year-old girl was killed and a 2-year-old boy was in critical condition after a woman stabbed them in a "guardian-related" incident, police in Louisiana said.
The attack was reported at about 11 a.m. Sunday on Law Street, New Orleans police said.
Officers responding to a call about a stabbing learned that the two children "sustained stab wounds to their bodies," police said in a statement.
Both children were taken in a private car to a hospital, where the girl died. The boy remained in critical condition, police said.
Janee Pedescleaux, 31, was arrested on suspicion of second-degree murder, attempted murder and second-degree cruelty to a juvenile, police said.
The preliminary investigation indicates that the incident is “guardian-related in nature,” the release said.
Pedescleaux is believed to be the person in a video shared Sunday on Instagram that showed a woman talking to the camera with blood visible on her body and shirt, a law enforcement source told the Times-Picayune/New Orleans Advocate.
In the clip she says through tears: “I’m done. My children are dead. I’m done. I’m done with life.” The video was later deleted.
Police would not confirm whether Pedescleaux was the woman in the video.
The Rev. Johnny Arvie, the pastor of Law Street Baptist Church, said the violence took place next door to his church during Sunday service.
“I gave my card to a family member so they could call me, but that’s about all I can do. And pray for the family and the community," Arvie told NBC affiliate WDSU of New Orleans.
“It’s sad. I’m concerned about the mental illness in our community and in our city,” Arvie said.
Pedescleaux was booked into the Orleans Parish Jail. It was not immediately clear whether she had legal representation.
