SCHENECTADY — Three teenagers who stole $20 from a pizza delivery worker at gunpoint in December are going to prison.

Schenectady County Court Judge Karen Drago sentenced Raymond Moules, 17, to 3 1/2 years in prison Friday and Armour Cherry, 18, and Curtis Fennicks, 16, each to 1 1/3 to 4 years in prison. Drago granted youthful offender status to each of them, sealing their records.

Moules received the longer sentence because he lured the Domino’s pizza delivery man to his home at 19 Linden St., where he and the other two robbed the man of $20 in cash, as well as pizza and chicken wings. The driver was not injured.
