MIAMI (CBSMiami/AP) — It will be federal prison time for two South Florida brothers who started a scheme that netted them $1.6 million in fraudulent tax refunds.

A federal judge on Friday sentenced 25-year-old Geto Dorlizier of Boynton Beach to more than nine years behind bars. His brother, 38-year-old Jourmel Thomas of Lake Worth, got more than five years in prison. They pleaded guilty previously to three charges, including conspiracy and aggravated identity theft.
