In January 2007, Brad Reay was convicted of killing his wife by stabbing her more than three dozen times and slashing her throat.
He enlisted his twin brother in a failed attempt to frame his wife's lover for the murder.
At trial, he tried to convince the jury that his young daughter had committed the crime.
On Tuesday, Aug. 27, Reay tried to convince the South Dakota Supreme Court that his trial attorney should have hired experts.
