A 13-year-old boy who killed his half-sister, practicing wrestling moves on her, will spend three years in a secure juvenile facility.

Armstrong Desvallons was sentenced Tuesday after admitting that he threw his body and elbow into 5-year-old Viloude Louis' chest about 20 times in June, when he was supposed to be babysitting her, according to The Times-Picayune. He was practicing moves like the "John Cena Slam" and the "Mark Henry Slam," named for wrestlers from World Wrestling Entertainment -- but there were no fake moves here.

Louis suffered broken ribs, internal bleeding and liver lacerations from the beating, which occurred at their Terrytown, LA., home, the New York Daily News reports.

Desvallons pleaded guilty last month and is expected to undergo treatment for grief, trauma and anger in a juvenile facility. He originally faced a sentence of up to five years, AL.com reports. He could potentially be released sooner than three years, depending on his progress in treatment.

On Tuesday, members of the church where Desvallons' family worshiped offered to take the boy into probationary custody, but Judge Andrea Price Janzen declined. The church members described Desvallons as a good kid, while Louis' stepfather reportedly called him disrespectful and argued that he'd do it again given the chance.
