A Madison man who admitted to robbing the Red Pepperoni at knifepoint in March was sentenced to 10 years in prison Monday.

Christian Williams, 18, of Madison, pleaded guilty to armed robbery and conspiracy to commit robbery, both class B felonies, in Superior Court.

Williams was 17 at the time of the incident but was charged as an adult.

Judge Alison Frazier sentenced Williams to 10 years in prison on each charge, though the sentences will run concurrently.

In March, two men entered the restaurant on West Main Street wearing masks and wielding knives, demanding money from the cash register while two other men provided a lookout, according to police.

Codefendants in the case are Jeremy D. Howard, 29, Bryant A. Bladen, 18, and William Zachary Barnes, 20.

Williams testified that he and Bladen were the two men who entered the restaurant.

Barnes was sentenced to six years in prison in November after pleading guilty to taking part in the robbery.
