BANGOR — A Caribou man faces up to 10 years in prison for cashing his dead mother-in-law’s retirement checks.

A federal court jury on Thursday convicted 61-year-old David Young, of Caribou, of conversion of government money and three counts of income tax fraud.

According to federal prosecutors, Young stole and cashed Civil Service Retirement System checks in 2004 and 2005 that were made out to his mother-in-law, who was deceased.

Prosecutors said Young then lied on his federal tax returns when he failed to report the income.
