White former Oklahoma police officer charged with killing daughter's black boyfriend heads to trial for fourth time. https://twitter.com/APCentralRegion/status/916650671264411648 https://apnews.com/d453c9d7945644b4...utm_source=Twitter&utm_medium=APCentralRegion TULSA, Okla. (AP) — Three hung juries in the case of a white former Oklahoma police officer charged with fatally shooting his daughter’s black boyfriend had one thing in common besides unwillingness to convict: Each had only one African-American juror. Race has been an undercurrent in ex-Tulsa officer Shannon Kepler’s first-degree murder case, which is headed for a fourth trial. Criminal law experts and U.S. Supreme Court cases point to the importance of racial identity and policing when it comes to jury selection, which is set to start Monday. Kepler, a 24-year veteran of the force, was off duty in August 2014 when he fatally shot 19-year-old Jeremey Lake, who had just started dating Kepler’s daughter. Kepler doesn’t deny pulling the trigger but says he did so only because he thought Lake was armed. No weapon was found on or near Lake’s body.
