A Sedgwick County jury has convicted a Wichita man of killing his wife.
The jury deliberated about an hour Thursday before finding 56-year-old Guy Palmer guilty of second-degree murder in the death of his 61-year-old wife, Debra Palmer.
Testimony at the trial, which began this week, showed Palmer stabbed his wife six times in December 2012 at their home after his wife told him she was having an affair. Police found Debra Palmer's body after Palmer turned himself into Sedgwick County authorities shortly after her death.
Defense lawyer Quentin Pittman said Palmer stabbed his wife during the heat of passion, but prosecutors argued the killing was premeditated.
Palmer is scheduled to be sentenced Dec. 5.
