GRETNA, La. (AP) — A 13-year-old Terrytown boy accused of killing his sister while practicing wrestling moves in June has pleaded guilty to negligent homicide.

The child admitted Tuesday to killing 5-year-old Viloude Louis, whose injuries included broken ribs, a lacerated liver and internal bleeding. The teenager said in a hand-written admission that he used moves named for wrestlers he saw on TV when he slammed his body or elbow into the little girl's torso multiple times.

The teenager was to stand trial on a charge of manslaughter Tuesday. He accepted a plea agreement on the lesser charge in Jefferson Parish juvenile court.

Sentencing is set for Dec. 4. The possible sentence ranges from probation to five years in a juvenile detention center.
