Operation Take Back America streamlines efforts and resources from the Department's Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN).

The Honorable D. Edward Snow, U.S. Magistrate Judge in the United States District Court for the Eastern District of Oklahoma, accepted the plea and ordered the completion of a presentence investigation report.

A U.S. District Court Judge will determine the sentence to be imposed after considering the U.S. Sentencing Guidelines and other statutory factors.
