Updated: Monday, July 17, 2017 9:59 am EDT

Kosoul Chanthakoummane's execution was scheduled to occur at 6 pm CDT, on Wednesday, July 19, 2017, at the Walls Unit of the Huntsville State Penitentiary in Huntsville, Texas. His execution has been stayed. Thirty-six-year-old Kosoul is convicted of the murder of 40-year-old Sarah Ann Walker on July 8, 2006, in Mckinney, Texas. Kosoul has spent the last nine years of his life on Texas’ death row.

His execution has been stayed by a state appellate court. Kosoul’s case has been sent back to trail court for review of the use of alleged discredited forensic sciences.

Kosoul spent time in juvenile facilities growing up for robbery. He also had attacked a friend, causing six fractured ribs, and a concussion, in addition to other injuries. Kosoul had previously been convicted of aggravated robbery and kidnapping in North Carolina, where he had served time, after which, he had been paroled to Texas to live with relatives. At the time of Sarah’s murder, he was wanted for a parole violation. While in Texas, he worked as a delivery man and a warehouse man.

On July 8, 2006, Mamie Sharpless, a real estate agent received a call from a man claiming to be “Chan Lee.” He wanted to look at a townhouse listed in the Craig Ranch neighborhood of McKinney, Texas. Mamie said that the man told her he had just moved to Texas from North Carolina. Mamie agreed to meet with the man between 11:30 am and noon.


Mamie and her husband arrived at the agreed meeting place and waited in the vehicle for “Chan” to arrive. A short time later, a man in a white Ford Mustang drove by and parked in front of a model home hear the listed townhome. The couple approached the car and asked the man if he was Chan, as he matched the description given over the phone. The man said he was not Chan. According to testimony at Kosoul Chanthakoummane’s trial, the man in the vehicle was Chanthakoummane. Chan never showed up.


While Mamie was showing the townhome to another potential buyer, Mamie’s husband observed Sarah Walker, another real estate agent arrive and enter the model home where she worked. After Mamie finished her showing, she and her husband went to Sarah’s model home. The entered around 1:10 pm and found it “ransacked,” with a large pool of blood in the dining room. A trail of blood led to the kitchen, where they discovered Sarah’s body.


An autopsy would later determine that Sarah had been struck over the head several times and that she attempted to defend herself. The attack was powerful enough to break her nose and fracture her teeth. Sarah was then stabbed 33 times, ten of which penetrated vital organs. Sarah also had a bite mark on her neck. A new Rolex watch and a ring were taken off her body.


DNA showed that some of the blood at the crime scene belonged to Chanthakoummane. When police questioned Chanthakoummane, he claimed that he had broken down in front of the model home and entered to get a drink of water, but was unable to turn on the facet. He claimed that “old cuts” on his hands “from work” could explain why his blood was at the crime scene. Additionally, a dentist matched the bite mark on Sarah’s neck to Chanthakoummane bite, although an expert for the prosecution rejected that conclusion.


Please pray for peace and healing for the family of Sarah Walker. Please pray for strength for the family of Kosoul Chanthakoummane. Please pray that if Kosoul is innocent, lacks the competency to be executed or should not be executed for any other reason, that evidence is presented prior to his execution. Please pray that Kosoul may come to find peace through a personal relationship with Jesus Christ, if he has not already.
