Russell Ray Bertram was convicted of first-degree murder in 2016. A jury found that he intentionally killed his girlfriend with a shotgun while they were hunting in Gregory County in 2009.
Bertram appeals his conviction on two points. He says the prosecution should not have been allowed to introduce evidence of his infidelity to his girlfriend. And he says the judge should have allowed the jury to know he had taken a polygraph.
The South Dakota Supreme Court heard arguments in the case on Wednesday, Oct. 4. SDPB's Victoria Wicks reports.
