A federal grand jury meeting in Greeneville Tuesday indicted Jeffrey Lee Stock, 41, of Newport, on charges of traveling in interstate commerce and failing to register as a sex offender.

Stock, who is now detained in the Grainger County Jail on charges placed by the Cocke County Sheriff's Office, will be arraigned on the federal charges on June 18 at 9 a.m., according to a news release from the U.S. Attorney's office.

U.S. Attorney Russ Dedrick said Stock violated the federal "Adam Walsh Act" by being a convicted sex offender who traveled from Florida to Tennessee and failed to register with authorities here.

Stock, he said, has been identified by Cocke County authorities as "a person of interest" in the disappearance of a Newport teenager.

If convicted, Stock faces a maximum term of imprisonment of 10 years; a maximum term of supervised release of up to life; a maximum fine of $250,000, and a $100 special assessment.

The indictment is the result of an investigation by the U.S. Marshal's Service, Cocke County Sheriff's Department, District Attorney General for the Fourth Judicial District, Tennessee Bureau of Investigation, and Knox County Sheriff's Office.
