PIERRE, S.D. (AP) – South Dakota Attorney General Marty Jackley says former Highmore Police Chief Ken Huber has lost a legal challenge to his conviction for first-degree murder in the shooting death of his wife. Huber was first convicted of murder in 2008 in the death of his wife, Pam. The South Dakota Supreme Court overturned that conviction, but Huber was convicted of first-degree murder in a second trial held in 2011. That trial was held in Huron. In an appeal in circuit court, Huber argued evidence presented at his second trial was unfair and his two defense attorneys Clint Sargent and Micheal Butler were ineffective. Circuit Judge John Brown of Pierre ruled he could find no fault with the evidence or the performance of Huber’s lawyers. Huber contends his pistol fired accidentally when he moved it from a bedroom dresser to a gun safe.
