Two Massachusetts residents, Ali Jaafar (63) and his son Yousef Jaafar (29), have been sentenced to federal prison for their involvement in a massive lottery fraud scheme. The Jaafars were part of a "ten-percenting" operation that involved cashing in 14,000 winning lottery tickets over a roughly 10-year period and then lying on their tax returns to cheat the IRS out of about $6 million. Ali Jaafar was sentenced to five years in prison and Yousef Jaafar was sentenced to three years in prison, with their third son Mohamed Jaafar receiving two years of probation. The U.S. Attorney’s Office in Boston said that the sentences should serve as a warning to those who engage in similar schemes.
