According to the arrest warrant, Leonardo put her 11-month-old, Aiden Leonardo, along with her 23-month-old in the bathtub with four to six inches of water before going outside to smoke a cigarette and have “me time.”

When she came back inside, the 23-month-old had turned the water back on, filling the tub, and the 11-month-old was floating on his back.

Leonardo’s preliminary hearing started on Tuesday.

The District Attorney General’s Office said during the proceedings a detective with the Knox County Sheriff’s Office testified that Leonardo did not intend to drown her son, but was neglectful.

The judge ruling the case will go over to the grand jury.

We’ll continue to follow Leonardo’s case as it progresses.
