A Robinson man has pleaded guilty in federal district court to an indictment charging conspiracy to manufacture methamphetamine.
Michael F. Yankey, 49, of Robinson, formerly of Chester, entered the plea Monday, according to Stephen R. Wigginton, U.S. Attorney for the Southern District of Illinois.
The conspiracy offense occurred between May 2011 and April 2012, in Williamson, Randolph, Jackson and Crawford counties. The factual basis at the plea hearing established that Yankey was involved with others in the manufacture of methamphetamine using the red phosphorous method.
The U.S. Attorney's office said numerous persons supplied Yankey with pseudoephedrine pills, iodine and matches for use in the manufacture of methamphetamine. Yankey later provided methamphetamine to those who supplied him with the precursors.
The offense carries a penalty of up to 20 years' imprisonment, a fine of not more than $1 million, and a term of supervised release of at least three years.
The ongoing investigation is being conducted by the Jackson County Sheriff's Office, Randolph County Sheriff's Office, Crawford County Sheriff's Office, Chester Police Department, Murphysboro Police Department, Robinson Police Department, and Drug Enforcement Administration. The case is assigned to Assistant U.S. Attorney Amanda A. Robertson for prosecution.
