TULSA, Okla. (AP) — An Oklahoma prosecutor says he isn't surprised or disappointed that a jury convicted a white former police officer of manslaughter instead of murder in his fourth trial for killing his daughter's black boyfriend. Tulsa County District Attorney Steve Kunzweiler said he's just relieved there was a conviction after former Tulsa officer Shannon Kepler's three previous murder trials ended with hung juries. "I'm just grateful that the jury gave us some finality with this verdict," Kunzweiler said. The jury convicted Kepler of first-degree manslaughter in the 2014 off-duty fatal shooting of 19-year-old Jeremey Lake, who had just started dating Kepler's then-18-year-old daughter, Lisa Kepler.
