GREENEVILLE, Tenn. -

A convicted sex offender who was later convicted of second-degree murder in Cocke County is headed to federal prison.

44-year-old Jeffery Lee Stock was sentenced in federal court in Greeneville to 46 months in prison after he pled guilty to interstate travel and failing to register as a convicted sex offender.

In January 2013, Stock pleaded guilty to second-degree murder, arson, and theft relating to the disappearance of Megan Maxwell. 

Under the terms of that plea agreement Stock will serve 100 percent of an 18 year sentence in state prison.

Federal Judge Ronnie Greer said he felt Stock was highly likely to commit future offenses and exhibits a very profound lack of respect for the law.

He ordered Stock to serve lifetime supervised when he is released. 

William C. Killian, U.S. Attorney for the Eastern District of Tennessee, stated, “This is a very good example of federal and state law enforcement authorities working together to maximize protection to local communities.  Because of the negotiated plea agreement Stock is now on federal supervised release for the remainder of his life, reducing the chances that he will victimize other young women again.”
