U.S. v. Larson, 460 F.3d 1200 (9th Cir. 2006)

Methamphetamine conspiracy convictions in Great Falls. Police orchestrated controlled purchases using paid informant Connie Riggs (met Larson through drug interaction) and confidential informant Jason Gilstrap (two buys from Laverdure), plus an unnamed CI who bought from Joy Lynn Poitra and Rick Lee Lamere. Poitra and Lamere agreed to testify against Larson and Laverdure in exchange for reduced charges. Ninth Circuit addressed cross-examination of cooperating coconspirators about sentences.
