Cooper Tyson Chapin, 23, of Twin Falls, Idaho, was sentenced today in U.S. District Court in Boise to 24 months in federal prison for conspiracy to distribute oxycodone, the U.S. Attorney's Office announced. Cooper is the fourth and final defendant sentenced in the Twin Falls area oxycodone trafficking conspiracy. U.S. District Judge Edward J. Lodge also ordered Chapin to serve three years of supervised release following his prison term. He pleaded guilty to the charge on January 3, 2011.

Chapin's three co-defendants, Troy Daniel Sabrosky, of Casper, Wyoming, James Toliver Latham, and Ryan J. Simmons, both of Twin Falls, previously admitted conspiring with Chapin to distribute oxycodone in the Twin Falls area. The three men pleaded guilty last fall pursuant to plea agreements. In February 2011, Judge Lodge sentenced Latham to 48 months in federal prison, Simmons to 30 months, and Sabrosky to 24 months. They will be required to serve three years of supervised release following their release from prison. Judge Lodge also ordered the men to forfeit $20,000.

In April 2010, the men were indicted for conspiracy to distribute oxycodone and distributing oxycodone in the Twin Falls area from March 2009 to March 2010. According to court documents, the investigation began in September 2009 after several sources provided information to Twin Falls law enforcement officials alleging Chapin's and others’ involvement in a oxycodone distribution ring. The investigation over the next eight months involved undercover purchases of oxycodone from the defendants. The defendants traveled to the Salt Lake City area on numerous occasions, sometimes several times a week, to purchase large quantities of oxycodone. The oxycodone was sold from the men’s residences in Twin Falls.

The case was investigated by the Twin Falls Police Department with assistance from the Drug Enforcement Administration.
