An illegal immigrant who was living in Denison will spend 10 years in a federal prison for dealing drugs.

This past March, 24-year-old Soyner Umanzor pleaded guilty to one count of conspiracy to distribute methamphetamine and four counts of aiding and abetting the distribution of methamphetamine.

Prosecutors says he sold meth within 1000 feet of two schools in Denison. Undercover cops bought over one-quarter of a pound of meth in a deal that involved Umanzor.

He’s been sentenced to 120 months in a federal prison, plus another decade of supervised probation after he’s released.

A variety of state, federal and local law enforcement worked on the investigation which caught Umanzor — including a U.S. Department of Justice task force investigating organized crime.
