Former Tulsa Officer Found Guilty On 2 Counts In Federal Murder Trial A federal jury has found former Tulsa Police officer Shannon Kepler guilty of murder in the 2nd degree, assault with a dangerous weapon, and not guilty of murder in the 1st degree. This is the fifth time that Kepler has gone to trial for the case but his first time in federal court. Kepler is accused of killing his daughter's boyfriend Jeremy Lake in 2014. In closing arguments on Monday, prosecutors argued that Kepler planned, prepared, and then shot and killed Lake. Prosecutors say Kepler saw that his daughter was in a new relationship with Lake on Facebook and didn't like it. They say he then he broke police policy by pulling up Lake's criminal history to get his address.
