The 6th District Court of Appeals in Texarkana has ordered a new trial for a Cass County man convicted of killing his wife.

The Texarkana Gazette reports that the court on Wednesday granted 50-year-old David Len Moulton's request for a new trial.

Moulton was convicted and sentenced to 60 years in prison in 2010 of the 2004 death of Rebecca Moulton. Her body was found in a pond on the couple's property in Atlanta, Texas. A cause of death could not be determined.

The appeals court agreed with arguments by defense attorney Jason Horton that the jury was given an improper instruction. The instruction said jurors could convict Moulton if they determined he asphyxiated his wife by unknown means.
