Sheriff Vic Regalado took the stand for the defense to tell the jury about his observations of Shelby when he supervised her while both worked for the Tulsa Police Department. He said she was an “exceptional officer” whom he trusted to help with the service of warrants, calling her “somebody you can count on” in stressful situations.

On cross-examination from Kunzweiler, he conceded that officers can make mistakes that affect citizens. But he told McMurray under further questioning that it’s less that likely an “exceptionally trained” officer such as Shelby would do so.

Tulsa police DNA analyst Tiffany Dyer testified for the prosecution about testing two swabs that had been swirled on top of Crutcher’s SUV’s driver’s side window. Dyer said she didn’t find any DNA on either swab, which means she cannot give a conclusive answer about whether Crutcher’s hand or arm touched the area.

The question is at issue because attorneys for Crutcher’s family have tried to disprove Shelby’s contention that he was reaching into his vehicle through the window when she shot him. Dyer said she tested the swabs on April 11, less than a month before the trial, at Walker’s request.
