Overview

• Dr. Marie Russell told jurors that scratch marks on John O’Keefe’s arm match canine bites rather than injuries from a vehicle impact.
• The defense moved for a mistrial after prosecutors noted the absence of dog DNA during cross-examination of the expert.
• Former Canton officer Kelly Dever recanted her 2023 FBI statement that she saw key figures near Read’s impounded SUV, citing a timeline that she said proved her error.
• Crash reconstruction expert Matthew DiSogra challenged prosecutors’ method of syncing Read’s SUV clock with O’Keefe’s phone data, arguing it cannot reliably establish the collision time.
• Defense attorneys introduced text messages from fired lead investigator Michael Proctor disparaging Read to argue that bias tainted the initial inquiry.
