Faced with incontrovertible video evidence of his guilt, a Missouri man has pleaded guilty to the vicious sucker-punching of a child, an unprovoked attack for which he will serve seven years in state prison, records show.

Cedric Moore, 28, copped earlier this month to a felony assault charge in connection with his walloping of a 12-year-old boy who was dancing last year on a downtown Cape Girardeau street corner.

The victim, Ethan Hagler, was with his hip-hop dance instructor when the 205-pound Moore exited an SUV and snuck up on the boy to deliver a roundhouse punch to the child’s head.

Hagler, who was left bleeding from the head and nose, was treated for his injuries at a local hospital.

As seen above, the assault was captured on a Facebook Live recording.

Moore, now in the custody of the Missouri Department of Corrections, was convicted in 2019 of felony domestic assault and sentenced to five years probation and ordered to "obey all laws" and complete an anger management program and a “Batterer's Program.”

Following Moore’s arrest for assaulting Hagler, prosecutors filed a probation violation charge against him. A judge this month ruled that Moore had violated his probation conditions and sentenced him to four years in prison, a term that will run concurrent to the seven-year sentence.
