A half dozen Evansville residents are arrested on warrants growing out of a federal indictment, unsealed Thursday afternoon. U.S. Attorney Joe Hogsett came to Evansville to discuss the arrests in connection with a meth ring. He calls the investigation a great effort involving several agencies at the federal, state, county and city levels. Hogsett says 29-year old Joshua Chaffin is the alleged ring leader, aided by 31-year old William Hollis and 30-year old Travis Sutton. He says mid-level distributors included 32-year old Gary Winstead, Jr. and 28-year old Michael Hartweck.
