Man confesses to shooting, killing Millard County, Utah officer during traffic stop. He recants, says passenger in his vehicle shot the officer. (It turns out the passenger was the officer’s brother.) A state court acquits the man of murder, but a federal jury convicts him of the same. (The brother isn’t charged; he dies of an overdose.) Tenth Circuit: Conviction affirmed. No error to withhold evidence of the state court acquittal from the federal jury.
