ROLLA, Mo. (News-Leader) — A federal lawsuit against Sgt. Dan Nash, a longtime investigator with the Missouri State Highway Patrol, climbed a step up the chain of command this month when the judge in the case allowed Nash’s longtime supervisor to be added as a defendant.

The lawsuit alleges that:

“Recently disclosed internal investigation files, coupled with the previous incidents implicate Nash’s supervisor, (George) Knowles, as having failed to supervise Nash and/or conspiring to cover up his misconduct. Had Knowles adequately supervised Nash, it is unlikely Plaintiff (Brad Jennings) would have ever been charged.”

Jennings was convicted in 2009 in the death of his wife Lisa. That verdict was based primarily on Nash’s testimony.

A Rolla judge determined that Jennings was wrongfully convicted and freed him in February 2018. Jennings had served 8½ years of a 25-year sentence. The attorney general’s office that year decided not to re-try Jennings.
