A convicted murderer who escaped from prison with the help of a prison volunteer has been sentenced to 10 more years for a federal firearms charge, U.S. Attorney Lanny Welch’s office said Monday.

John Manard, 30, escaped in February 2006 from Lansing Correctional Facility by hiding in a dog crate with the help of Toby Young, who ran a dog-training program at the prison.

At the time of the escape, Manard was serving a life sentence for first-degree murder, aggravated robbery and criminal possession of a firearm for the 1996 carjacking and murder of a Johnson County man.

After 12 days of freedom, Manard and Young were captured in rural Tennessee. Manard pleaded guilty to one count of unlawful possession of a firearm after a felony conviction and was sentenced to nearly 11 years in custody for the escape.

His firearms sentence will be served after the sentences for murder and jailbreak, said Jim Cross, Welch’s spokesman.

Young pleaded guilty in federal court to one count of giving a firearm to a convicted felon. She was sentenced to 27 months and released from federal custody in May 2008. She was discharged from state custody in February after completing her sentence for aiding and abetting aggravated escape and introducing contraband — a cellular phone — into the prison.
