After spending six years awaiting trial, a jury in Salem convicted Jesse Johnson in 2004. Prosecutors relied on an alleged confession to the murder of Harriet Thompson that Johnson made to a fellow drug user named Donald “Shorty” Blocker. But the jury did not hear the full story. If they had, they may have had doubts about the police investigators at the heart of the Johnson case: Detectives Craig Stoelk and Mike Quakenbush.
