A Georgia mother is facing a second-degree murder charge after her 5-year-old son allegedly shot and killed his twin brother with a gun she left loaded in a purse near her bed, police said.

La’Necia Bennett was in court Thursday, a day after the fatal shooting inside her Columbus home. Arrest warrants reportedly say she left the firearm unsecured in a purse beside her bed. The twins were playing in her bedroom when one of them reportedly fired the gun, striking his brother in the chest, according to 11Alive News. Bennet was home at the time.

A neighbor told 11Alive she saw first responders rush into the Village Apartments and carry the child out on a stretcher while performing CPR.

“I just seen the ambulance go inside the apartment and they came out with a child and put him on a stretcher and started doing CPR,” the unidentified neighbor said. “”That could be my child, that could be anyone’s child. I instantly got emotional — like I said, I have a three-year-old and a four-year-old. So, yeah, that was really emotional.”

The child was later identified as Jeremiah Emmanuel George Jr., his grandmother told the outlet. The investigation remains ongoing, but Bennett now faces additional charges of cruelty to children.

Criminal defense attorney Kim Frye told 11Alive the murder charge stems from what police allege was negligence — not securing the weapon and failing to supervise the children closely enough.

“Police have determined, thus far, on the minimum of facts that they have, her watching him, not well enough for him to be shot by another child in the household and then he died—that’s why she’s charged with murder,” Frye said.

Frye added the child cruelty charge was “based on the supervising adult’s negligence.”
