A man convicted of fatally shooting a couple near De Soto in 1996 has had his death penalty overturned for a third time.

The St. Louis Post-Dispatch reports that U.S. District Judge Catherine Perry called the portion of the trial that led up to Carman Deck’s latest death sentence “fundamentally unfair.” She ordered him to serve life in prison without parole for the killings of James and Zelma Long more than 20 years ago.

It’s not yet clear whether the state will appeal.

Two other death sentences also were overturned, including by the U.S. Supreme Court in 2005 because he had been shackled in the presence of jurors.
