Texas is planning to execute Kosoul Chanthakoummane, a 41 year old man, who was convicted of a 2006 murder in a model home in Collin County, at 6pm on Wednesday.
Kosoul Chanthakoummane who stabbed a real estate agent more than 30 times using a home decor piece is set to be executed by lethal injection.
Prosecutors say Kosoul Chanthakoummane entered the model home and then beat Walker with a wooden plant stand and stabbed her before stealing her Rolex watch and a silver ring, which were never found.
DNA evidence showed Chanthakoummane’s blood was found in various places inside the model home, including under Walker’s fingernails.
Walker had been a top-seller for home builder D.R. Horton. She had two children.
Chanthakoummane admitted that he was in the model home, but says he only entered to get a drink of water.
He maintains his innocence in Walker’s death.
“I am innocent,” Chanthakoummane said in a letter filed in federal court in March.
His attorneys had asked the Texas Court of Criminal Appeals to stay his execution, challenging the DNA evidence, which was previously described by the appeals court as the “linchpin of the state’s case.” The appeals court this week denied the request. Eric Allen, one of Chanthakoummane’s attorneys, said he hadn’t decided if he would file a final appeal with the U.S. Supreme Court.
His attorneys had argued new science raises the possibility Chanthakoummane’s DNA could have been transferred to Walker’s fingernails without any direct contact between the two.
