Lionel Gillette pleaded guilty on Tuesday afternoon to attempted manufacturing of methamphetamine and possession of a pipe bomb on different dates in 2011.

Gillette, 45, of St. Clair, pleaded guilty to attempting to manufacture in excess of 50 grams of methamphetamine and possession of a destructive device — a pipe bomb — before United States District Judge Henry Autrey. Sentencing has been set for Oct. 15, 2013.

The charges carry penalties ranging from five to 40 years in prison and/or fines up to $5 million. In determining the actual sentences, a judge is required to consider the U.S. sentencing guidelines, which provide recommended sentencing ranges.

The case was investigated by the Franklin County Narcotics Enforcement Unit and the Bureau of Alcohol, Tobacco and Firearms. Assistant United States Attorney James Delworth is handling the case for the U.S. Attorney's Office.

Information about Gillette's guilty plea was released after The Missourian's Wednesday publishing deadline on Tuesday. For more on this story, see the Weekend Missourian.
