An Ohio man who stole about $8 million from an armored car company where he worked has been sentenced to eight years in prison.

Twenty-three-year-old Roger Dillon of Youngstown got a stiffer sentence Thursday than the one his girlfriend, Nicole Boyd, received Wednesday.

U.S. District Judge John Adams sentenced Boyd to five years in prison, noting that she wasn't the mastermind of the heist.

Dillon plotted the crime and had faced a maximum of 25 years in prison.

His mother, Sharon Gregory, also will be sentenced Thursday. She conspired with the couple and fled with them to West Virginia.

All three pleaded guilty in March in what federal prosecutors said was one of the largest thefts ever in northern Ohio.
