A federal judge recently sentenced four people on crimes relating to aircraft, child pornography and methamphetamine, according to a news release from the Wyoming U.S. Attorney's Office.

U.S. District Court Judge Alan Johnson sentenced Scott Michael Lewis, 27, of Lakewood, Colo., for operating an unregistered aircraft. Lewis received three years of probation and was ordered to pay a $100 special assessment and a $1,000 fine.

This case was investigated by the U.S. Department of Transportation Office of Inspector General and the U.S. Department of Homeland Security Immigration and Customs Enforcement.

Johnson sentenced Garrett Ross Castleman, 27, of Casper for possession of child pornography. He received four months imprisonment, to be followed by five years of probation. Castleman will be required to wear an electronic home monitoring device for the first four months of supervised release. Johnson also ordered Castleman to pay a $100 special assessment and a $400 fine. This case was investigated by the Wyoming Division of Criminal Investigation Internet Crimes Against Children Task Force.
