LOS ANGELES (AP) — A former federal immigration agent has been sentenced to one month behind bars and a $5,000 fine for lying to investigators about a fraud scheme that netted her and her husband more than $500,000.

City News Service reports 54-year-old Taryn Johnston was on the payroll for six years at a job her husband got her for at U.S. Immigration and Customs Enforcement — where he approved her timesheets for six years, though she did virtually no work for the agency.

Prosecutors say she also frequently claimed overtime and holiday pay.

Her husband, Frank Johnston, retired from ICE in 2009 after a 31-year career.

He was convicted in the case last year of multiple counts of wire fraud and theft of government property and is scheduled for sentencing next month.
