Glassman’s statement reads.

Marlon Miller, special agent in charge for Homeland Security Investigations Detroit, which covers Michigan and Ohio, said in a prepared statement that the best way to “target and dismantle a criminal group is to hit them where it hurts the most - in their wallets.”

“This conviction and the guilty pleas of the other defendants are a testament to the immeasurable value of the Bulk Cash Smuggling Task Force and the unique expertise and authorities each member agency brings to bear in these complex investigations,” Miller’s statement reads.

Grande was sentenced in November 2015 to 90 months in prison and sentencing is pending for Felix. A sentencing date has not been set for Pavon, who as an illegal immigrant, faces deportation after serving his sentence.
