BANGOR – A Bangor man whose firefighter father last year interrupted a burglary at his mobile home in Corinth was sentenced Thursday in U.S. District Court to 10 years in federal prison, the maximum allowed, on gun charges.

Joshua W. Cass, 21, also was sentenced to three years of supervised release after he has completed his sentence and ordered to pay $735 in restitution, according to the U.S. Attorney’s Office.

He is expected to plead guilty to related state charges and be sentenced on Tuesday in Penobscot County Superior Court, according to Michael Roberts, deputy district attorney for Penobscot County.

Cass waived indictment and pleaded guilty in January in federal court to two counts of being a felon in possession of firearms, two counts of possession of stolen firearms, and one count of making an illegal firearm.

The weapons were taken in April 2005 in two separate burglaries a week apart in Corinth.

Cass received the maximum sentence on the federal charges because of the large number of stolen firearms involved and because Cass sawed the barrel off one of them, Assistant U.S. Attorney James Moore said Friday,

Jeffrey Cass, a firefighter in Corinth, returned home to his Black Road residence on his lunch break on April 27 to discover his son, along with Joshua Emerson and Urquhart, trying to steal hunting equipment, police said. James Emerson and McGraw were arrested nearby in a waiting car.

The suspects allegedly had set their sights on four hunting bows, three dozen arrows, two shotguns and a pellet gun, valued at approximately $3,000, before the firefighter thwarted the burglary.

The younger Cass and his co-defendants planned to hand the weapons over to a drug dealer who had threatened Cass and demanded $1,300 in drug money the previous week, according to court documents.

In addition to Cass, Douglas Urquhart Jr., 27, Joshua L. Emerson, 21, and James A. Emerson, 23, all of Bangor, and Megan McGraw, 20, of Eddington were indicted in connection with the break-in.

Cass and the Emerson brothers also have been charged in the April 21, 2005, burglary of another house on the same road from which six firearms were stolen.

McGraw was sentenced last month in Penobscot County Superior Court to five years in prison with all but nine months suspended, and three years of probation for driving the get-away car in the break-in at Cass’ father’s home.

In unrelated incidents, Cass and Urquhart last month were indicted by the Hancock County grand jury on 12 counts each of burglary and 10 counts each of theft in that county. They are accused of breaking into several camps around Green Lake last April.

The cases in state and federal courts against Cass and the others are pending.
