A.J. Ex Rel. Dixon v. Tanksley, 822 F.3d 437

Background

On June 1, 2008, Lt. Donnell Tanksley observed a yellow motorcycle he believed was driving recklessly, attempted a stop, and shortly thereafter encountered a fatal collision between a yellow motorcycle (driven by Robert Jason Johnson) and a white car driven by Bryant Howard.
Officer Matthew Waggoner prepared an accident report containing narrative statements from Tanksley, Howard, and passenger Yolanda Diggs; the report listed Johnson’s speed and improper lane usage as probable contributing circumstances. No accident reconstruction was ultimately performed.
Johnson died; his insurer denied accidental-death benefits based largely on the accident report, and a subsequent Missouri wrongful-death jury trial against Howard returned a verdict for Howard.
In 2013 Johnson’s estate sued Tanksley, Waggoner, and Sgt. Perri Johnson under 42 U.S.C. § 1983 for substantive due process, equal protection, and conspiracy claims based on alleged falsification of the report and inadequate investigation; the district court granted summary judgment for defendants and denied the estate’s motion for sanctions against Howard and Diggs for depositions no-shows.
On appeal, the Eighth Circuit reviewed the summary judgment de novo and affirmed, holding the estate failed to show the accident report was materially false or that officers’ investigative omissions rose to conscience-shocking conduct.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Were the officers’ accident report statements materially false (due process claim)?	Report contained discrepancies and omissions that falsely blamed Johnson and caused insurance denial and loss at state trial.	Discrepancies were minor, eyewitness accounts corroborated report, and no material falsehood shown that a jury or insurer would rely on.	No material falsity shown; summary judgment for defendants.
Did officers’ failure to perform measurements/reconstruction or interview others constitute conscience-shocking investigative failure?	Officers failed to adequately investigate (no reconstruction, limited interviews), so violated substantive due process.	No evidence of additional witnesses or unpreserved evidence; department procedure placed reconstruction request with dispatcher; officers not trained in reconstruction.	No conscience-shocking failure; summary judgment for defendants.
Equal protection claim (racial motive)?	Officers (Black) tried to scapegoat Johnson (White); assignment of Waggoner to prepare report suggests cover-up.	No evidence the report was materially false or racially motivated.	Claim fails because no underlying constitutional violation proved; summary judgment affirmed.
Sanctions for deposition nonappearance (Howard/Diggs)?	Estate sought costs/fees and contempt after last-minute reschedule attempt and failure to appear.	Howard/Diggs said scheduling confusion and counsel communication failures justified denial of sanctions.	District court did not abuse discretion denying sanctions; conflict was a wash.
