A repeat drug offender will serve 10 years in prison for selling cocaine in a school zone.The defendant, Jason Biles, was already serving time in the state penitentiary for past crimes when he was hit with his most recent indictment, that being the delivery of cocaine to an undercover agent near Bobby Ray Elementary School on Chancery Street.As a result of his conviction following a jury trial earlier this year, Circuit Court Judge Bart Stanley sentenced him to serve 10 years in prison last week. The sentence will be served consecutively with any other sentence he is serving.His sentence comes after he made two sales of cocaine to an undercover agent who was working on a drug sting operation with local law enforcement. Investigators said he twice delivered the illegal narcotic on two separate dates, the last of which involved his meeting with the agent at a location near Bobby Ray.Under state law, any sale of a controlled substance within 1,000 feet of a school, child care agency, park, library or recreational facility is considered sale within a school zone and provides greater penalties for the crime.In his confession, given after he was convicted following trial, Biles said, “The informant called my phone to purchase cocaine and I met with him and sold cocaine to him.”In another school zone case, Eddie Woodrow Young was sentenced to six years in prison and fined $4,000 for delivery of meth.
